Sucralose-6-acetate is an intermediate and impurity in the manufacture of sucralose, and recent commercial sucralose samples were found to contain up to 0.67% sucralose-6-acetate. Studies in a rodent model found that sucralose-6-acetate is also present in fecal samples with levels up to 10% relative to sucralose which suggest that sucralose is also acetylated in the intestines. A MultiFlow® assay, a high-throughput genotoxicity screening tool, and a micronucleus (MN) test that detects cytogenetic damage both indicated that sucralose-6-acetate is genotoxic. The mechanism of action was classified as clastogenic (produces DNA strand breaks) using the MultiFlow® assay. The amount of sucralose-6-acetate in a single daily sucralose-sweetened drink might far exceed the threshold of toxicological concern for genotoxicity (TTCgenotox) of 0.15 µg/person/day. The RepliGut® System was employed to expose human intestinal epithelium to sucralose-6-acetate and sucralose, and an RNA-seq analysis was performed to determine gene expression induced by these exposures. Sucralose-6-acetate significantly increased the expression of genes associated with inflammation, oxidative stress, and cancer with greatest expression for the metallothionein 1 G gene (MT1G). Measurements of transepithelial electrical resistance (TEER) and permeability in human transverse colon epithelium indicated that sucralose-6-acetate and sucralose both impaired intestinal barrier integrity. Sucralose-6-acetate also inhibited two members of the cytochrome P450 family (CYP1A2 and CYP2C19). Overall, the toxicological and pharmacokinetic findings for sucralose-6-acetate raise significant health concerns regarding the safety and regulatory status of sucralose itself.}, journal={Journal of Toxicology and Environmental Health, Part B}, publisher={Informa UK Limited}, author={Schiffman, Susan S. and Scholl, Elizabeth H. and Furey, Terrence S. and Nagle, H.

The field of artificial olfaction has recruited and stimulated interdisciplinary research and commercial development for several applications that include malodor measurement, medical diagnostics, food and beverage quality, environment and security. Over the last century, innovative engineers and scientists have been focused on solving a range of problems associated with measurement and control of odor. The IEEE Sensors Journal has published Special Issues on olfaction in 2002 and 2012. Here we continue that coverage. In this article, we summarize early work in the 20 th Century that served as the foundation upon which we have been building our odor-monitoring instrumental and measurement systems. We then examine the current state of the art that has been achieved over the last two decades as we have transitioned into the 21 st Century.

In the conclusions of their paper, they claim that LNCS 1) do not affect gut microbiota at use levels and 2) are safe at levels approved by regulatory agencies. Both of these claims are incorrect. The scientific literature on LNCS clearly indicates that it is inappropriate to draw generalized conclusions regarding effects on gut microbiota and safety issues for compounds that vary widely chemical structure and pharmacokinetics. Scientific studies on the sweetener sucralose, used here as a representative LNCS, indicate that this organochlorine compound unequivocally and irrefutably disrupts the gut microbiome at doses relevant to human use.

Standards provide performance criteria that technical engineers can use to design products to optimize the reliability and safety of new products. For example, standards have played a decisive role in the development of products associated with the senses of vision, audition, and touch. The design of products that perform automated “visual” tasks including unmanned vehicles, autonomous robots, optical tracking systems, and highway traffic monitoring devices has relied heavily on standards as well as technical regulations. Likewise, standards related to the sense of hearing have played a major role in the development of devices and systems that assist or mimic “audition” including cochlear implants, hearing aids, and voice and speech recognition systems. Standards related to the sense of touch have been seminal in the design of robotic arms and prosthetic hands. Unlike the senses of vision, audition, and touch, there are, however, no formal standards for electronic devices called e-noses and e-tongues that are designed to detect and evaluate odors and tastes. The purpose of this opinion piece is to give a brief background on the senses of smell and taste, to describe why standards for e-noses and e-tongues are needed, and to call for IEEE volunteers to participate and collaborate on technical standards development to ensure that machine olfaction and taste provide reliable and reproducible results that are comparable to human smell and taste.}, number={9}, journal={PROCEEDINGS OF THE IEEE}, author={Nagle, H.

Sucralose was administered to 10 rats by gavage daily for 40 days at an average dosage of 80.4 mg/kg/day. The dosages were within the range utilized in historical toxicology studies submitted for regulatory approval in North America, Europe, and Asia. Feces and urine were collected individually from each animal for every 24-hr period during the 40-day dosing period. Analysis of the urine and fecal extracts by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) revealed two new biotransformation products that have not previously been reported. These two metabolites are both acetylated forms of sucralose that are less polar and hence more lipophilic than sucralose itself. These metabolites were present in urine and feces throughout the sucralose dosing period and still detected at low levels in the urine 11 days after discontinuation of sucralose administration and 6 days after sucralose was no longer detected in the urine or feces. The finding of acetylated sucralose metabolites in urine and feces do not support early metabolism studies, on which regulatory approval was based, that claimed ingested sucralose is excreted unchanged (i.e. not metabolized). The historical metabolic studies apparently failed to detect these metabolites in part because investigators used a methanol fraction from feces for analysis along with thin layer chromatography and a low-resolution linear radioactivity analyzer. Further, sucralose was found in adipose tissue in rats two weeks after cessation of the 40-day feeding period even though this compound had disappeared from the urine and feces. Thus, depuration of sucralose which accumulated in fatty tissue requires an extended period of time after discontinuation of chemical ingestion. These new findings of metabolism of sucralose in the gastrointestinal tract (GIT) and its accumulation in adipose tissue were not part of the original regulatory decision process for this agent and indicate that it now may be time to revisit the safety and regulatory status of this organochlorine artificial sweetener.}, number={18}, journal={JOURNAL OF TOXICOLOGY AND ENVIRONMENTAL HEALTH-PART A-CURRENT ISSUES}, author={Bornemann, Volker and Werness, Stephen C. and Buslinger, Lauren and Schiffman, Susan S.}, year={2018}, pages={913–923} }

The approach uses a field asymmetric ion mobility spectrometer and a photoionization detector to measure volatile organic compounds, and a multivariate technique to map sensor data into human ratings.

Sucralose interacts with chemosensors in the alimentary tract that play a role in sweet taste sensation and hormone secretion. In rats, sucralose ingestion was shown to increase the expression of the efflux transporter P-glycoprotein (P-gp) and two cytochrome P-450 (CYP) isozymes in the intestine. P-gp and CYP are key components of the presystemic detoxification system involved in first-pass drug metabolism. The effect of sucralose on first-pass drug metabolism in humans, however, has not yet been determined. In rats, sucralose alters the microbial composition in the gastrointestinal tract (GIT), with relatively greater reduction in beneficial bacteria. Although early studies asserted that sucralose passes through the GIT unchanged, subsequent analysis suggested that some of the ingested sweetener is metabolized in the GIT, as indicated by multiple peaks found in thin-layer radiochromatographic profiles of methanolic fecal extracts after oral sucralose administration. The identity and safety profile of these putative sucralose metabolites are not known at this time. Sucralose and one of its hydrolysis products were found to be mutagenic at elevated concentrations in several testing methods. Cooking with sucralose at high temperatures was reported to generate chloropropanols, a potentially toxic class of compounds. Both human and rodent studies demonstrated that sucralose may alter glucose, insulin, and glucagon-like peptide 1 (GLP-1) levels.

Industrialized animal agriculture creates odorant compounds that are components of a mixture of agents that could trigger symptoms reported by neighbors of livestock operations.ObjectiveWe quantified swine odor episodes reported by neighbors and the relationships of these episodes with environmental measurements.MethodsBetween September 2003 and September 2005, 101 nonsmoking volunteers living within 1.5 mi of industrial swine operations in 16 neighborhoods in eastern North Carolina completed twice-daily odor diaries for approximately 2 weeks. Meteorological conditions, hydrogen sulfide, and particulate matter ≤ 10 μm in aerodynamic diameter (PM10) were monitored in each neighborhood. We used mixed models to partition odor variance within and between people and between neighborhoods, and to quantify relationships between environmental factors and odor.ResultsParticipants reported 1,655 episodes of swine odor. In nine neighborhoods, odor was reported on more than half of study-days. Odor ratings were related to temperature, PM10, and semivolatile PM10 in standard but not mixed models. In mixed models, odor increased 0.15 ± 0.05 units (mean ± SE) for a 1-ppb increase in H2S, and 0.45 ± 0.14 units for a 10-μg/m3 increase in PM10 at wind speeds > 6.75 miles per hour. The odds of reporting a change in daily activities due to odor increased 62% for each unit increase in average odor during the prior 12 hr (t-value = 7.17).ConclusionsThis study indicates that malodor from swine operations is commonly present in these communities and that the odors reported by neighbors are related to objective environmental measurements and interruption of activities of daily life.}, number={10}, journal={Environmental Health Perspectives}, publisher={Environmental Health Perspectives}, author={Wing, Steve and Horton, Rachel Avery and Marshall, Stephen W. and Thu, Kendall and Tajik, Mansoureh and Schinasi, Leah and Schiffman, Susan S.}, year={2008}, month={Oct}, pages={1362–1368} }

The trajectory and spatial distribution of odor emitted at each facility were modeled at 200 and 400 m downwind from each site under two meteorological conditions (daytime and nighttime) using a Eulerian-Lagrangian model. To predict the dispersion of odor downwind, the geographical area containing the odorant sources at each facility was partitioned into 10-m2 grids on the basis of satellite photographs and architectural drawings. Relative odorant concentrations were assigned to each grid point on the basis of intensity measurements made by the trained odor panel at each facility using a 9-point rating scale. The results of the modeling indicated that odor did not extend significantly beyond 400 m downwind of any of the test sites during the daytime when the layer of air above the earth's surface is usually turbulent. However, modeling indicated that odor from all full-scale farms extended beyond 400 m onto neighboring property in the evenings when deep surface cooling through long-wave radiation to space produces a stable (nocturnal) boundary layer. The results also indicated that swine housing, independent of waste management type, plays a significant role in odor downwind, as do odor sources of moderate to moderately high intensity that emanate from a large surface area such as a lagoon. Human odor assessments were utilized for modeling rather than instrument measurements of volatile organic compounds (VOCs), hydrogen sulfide, ammonia, or particulates less than 10 microm in diameter (PM10) because these physical measurements obtained simultaneously with human panel ratings were not found to accurately predict human odor intensity in the field.}, number={9}, journal={JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION}, author={Schiffman, Susan S. and Graham, Brevick G. and Williams, C.

It is emphasized from the outset that sensory losses in critically-ill patients may or may not be related to their current medical condition. The present paper provides an overview of all five senses (vision, hearing, taste, smell and touch) and describes the factors that contribute to sensory losses in critically-ill patients, including medications, medical conditions and treatments and the process of aging itself. Cancer and stroke are two critical illnesses in which profound sensory decrements often occur. Many sensory complaints in patients with cancer are related to alteration in sensory signals caused by damage to the sensory receptors. However, some complaints, such as taste aversions in patients with cancer, are not related to altered sensory physiology per se but to learned aversions that arise during the noxious effects of radiotherapy and chemotherapy. The paper also reviews a study in which the sensory performance (of all five senses) was compared in three groups of elderly subjects: (1) patients who had undergone coronary artery bypass surgery; (2) patients with cardiovascular conditions but with no history of surgery; (3) healthy non-medicated age-matched controls. Performance of patients who had undergone coronary artery bypass surgery was worse than that for the other two groups, with taste and smell losses greater than for the other senses. The study demonstrates that critical illness (e.g. coronary artery bypass surgery) can exacerbate sensory losses in an older cohort.}, number={3}, journal={Proceedings of the Nutrition Society}, publisher={Cambridge University Press (CUP)}, author={Schiffman, Susan S.}, year={2007}, month={Jul}, pages={331–345} }

Specifically, the model was used to simulate the dispersion of odor from a confined animal feeding operation (CAFO) under different meteorological conditions: (1) during daytime when the boundary layer is usually turbulent due to ground-level heating from solar short wave radiation, and (2) during the evening when deep surface cooling through long-wave radiation to space recreates a stable (nocturnal) boundary layer. Aerial photographs were taken of the CAFO, and the geographical area containing the odorant sources was partitioned into 10 m2 grids. Relative odorant concentrations present at each grid point that corresponded to an odor source were measured on site and then entered into a database. The predicted odor dispersion distance was found to be greater at night-time than during daytime and was consistent with field reports from individuals living near the CAFO. The model utilizes single numbers that represent relative concentrations or intensities (e.g. from an electronic nose or human judgments) to simulate downwind dispersion. The advantages of this algorithm over standard Gaussian plume models are that: the velocity variances and covariances among its three components, integral time scale (a measure of eddy coherency), and complex boundary conditions (e.g. complex release points, surface boundary conditions) are explicitly considered.}, number={1}, journal={Sensors and Actuators B: Chemical}, publisher={Elsevier BV}, author={Schiffman, S.S. and McLaughlin, B. and Katul, G.G. and Nagle, H.T.}, year={2005}, month={Apr}, pages={122–127} }

@article{schiffman_williams_2005, title={Science of odor as a potential health issue}, volume={34}, DOI={10.2134/jeq2005.0129a}, abstractNote={Historically, unpleasant odors have been considered warning signs or indicators of potential risks to human health but not necessarily direct triggers of health effects. However, citizen complaints to public health agencies suggest that odors may not simply serve as a warning of potential risks but that odor sensations themselves may cause health symptoms. Mal-odors emitted from large animal production facilities and wastewater treatment plants, for example, elicit complaints of eye, nose, and throat irritation, headache, nausea, diarrhea, hoarseness, sore throat, cough, chest tightness, nasal congestion, palpitations, shortness of breath, stress, drowsiness, and alterations in mood. There are at least three mechanisms by which ambient odors may produce health symptoms. First, symptoms can be induced by exposure to odorants (compounds with odor properties) at levels that also cause irritation or other toxicological effects. That is, irritation--rather than the odor--is the cause of the health symptoms, and odor (the sensation) simply serves as an exposure marker. Second, health symptoms from odorants at non-irritant concentrations can be due to innate (genetically coded) or learned aversions. Third, symptoms may be due to a co-pollutant (such as endotoxin) that is part of an odorant mixture. Objective biomarkers of health symptoms must be obtained, however, to determine if health complaints constitute health effects. One industry that is receiving much attention, worldwide, related to this subject is concentrated animal production agriculture. Sustainability of this industry will likely necessitate the development of new technologies to mitigate odorous aerial emissions. Examples of such "environmentally superior technologies" (EST) developed under the initiative sponsored through agreements between the Attorney General of North Carolina and Smithfield Foods and Premium Standard Farms are described.}, journal={Journal of Environmental Quality}, author={Schiffman, S.S. and Williams, C.M.}, year={2005}, pages={129–138} }

The natural log of slgA concentration and secretion rate declined, on average, 0.058 (0.032) and 0.116 (0.103), respectively, for each incremental 1-unit increase in reported odor from 4 to 9, adjusted for time of day, suggesting reduced levels of sIgA in response to moderate or high odor. Findings support the hypothesized immunosuppressive effect of malodor on mucosal immunity and provide preliminary data useful in understanding health effects related to malodor from industrial hog farming operations.}, number={2}, journal={Archives of Environmental Health: An International Journal}, publisher={Informa UK Limited}, author={Avery, Rachel C. and Wing, Steve and Marshall, Stephen W. and Schiffman, Susan S.}, year={2004}, month={Feb}, pages={101–108} }

The sweet stimuli tested in this study were binary and ternary blends of 14 sweeteners that varied widely in chemical structure. A trained panel evaluated the sweetness intensity over four sips of a given mixture presented at 30 s intervals. The individual components in the binary sweetener combinations were intensity-anchored with 5% sucrose, while the individual sweeteners in the ternary mixtures were intensity-anchored with 3% sucrose (according to formulae developed previously). Each self-mixture was also evaluated (e.g. acesulfame-K-acesulfame-K). The main finding of this study was that mixtures consisting of two or three different sweeteners exhibited less reduction in sweetness intensity over four repeated sips than a single sweetener at an equivalent sweetness level. Furthermore, ternary combinations tended to be slightly more effective than binary combinations at lessening the effect of repeated exposure to a given sweet stimulus. These findings suggest that the decline in sweetness intensity experienced over repeated exposure to a sweet stimulus could be reduced by the blending of sweeteners.}, number={3}, journal={Chemical Senses}, publisher={Oxford University Press (OUP)}, author={Schiffman, S.

The safety of aspartame and its metabolic constituents was established through extensive toxicology studies in laboratory animals, using much greater doses than people could possibly consume. Its safety was further confirmed through studies in several human subpopulations, including healthy infants, children, adolescents, and adults; obese individuals; diabetics; lactating women; and individuals heterozygous (PKUH) for the genetic disease phenylketonuria (PKU) who have a decreased ability to metabolize the essential amino acid, phenylalanine. Several scientific issues continued to be raised after approval, largely as a concern for theoretical toxicity from its metabolic components--the amino acids, aspartate and phenylalanine, and methanol--even though dietary exposure to these components is much greater than from aspartame. Nonetheless, additional research, including evaluations of possible associations between aspartame and headaches, seizures, behavior, cognition, and mood as well as allergic-type reactions and use by potentially sensitive subpopulations, has continued after approval. These findings are reviewed here. The safety testing of aspartame has gone well beyond that required to evaluate the safety of a food additive. When all the research on aspartame, including evaluations in both the premarketing and postmarketing periods, is examined as a whole, it is clear that aspartame is safe, and there are no unresolved questions regarding its safety under conditions of intended use.}, number={2}, journal={Regulatory Toxicology and Pharmacology}, publisher={Elsevier BV}, author={Butchko, Harriett H. and Stargel, W.Wayne and Comer, C.Phil and Mayhew, Dale A. and Benninger, Christian and Blackburn, George L. and de Sonneville, Leo M.J. and Geha, Raif S., (Allergy) and Hertelendy, Zsolt and Koestner, Adalbert and et al.}, year={2002}, month={Apr}, pages={S1–S93} }

The goal of this study was to assess DD patients in the following areas: sensory capacities, decision-making style, and complex reasoning. Ten DD patients and 10 matched normal controls completed the following (1) smell, taste, and vision testing; (2) a probabilistic inference test in which subjects made probability decisions; and (3) a gambling task assessing complex reasoning. No significant difference was found between DD subjects and normals for taste acuity, olfactory acuity, or olfactory discrimination. No difference in visual acuity was noted, but sample size was limited. In addition, DD subjects required significantly less data to make probability decisions than normal controls. Despite using less data, DD subjects were as certain as controls regarding the accuracy of their decisions. As for complex reasoning, DD subjects performed as well as normal controls, but tended to surmise the purpose of the task sooner than normals, a difference that approached significance. In conclusion, these results suggest no differences between DD and normal subjects regarding olfaction, taste, and vision. The reasoning studies suggest that DD subjects may have a “cognitive set” that predisposes them to make conclusions with significantly less data than normals. Further, the study suggests that this reasoning difference generalizes to events outside the DD subjects' delusional realm and can be evoked in an experimental environment.}, number={3}, journal={Comprehensive Psychiatry}, publisher={Elsevier BV}, author={Conway, Charles R. and Bollini, Anna M. and Graham, Brevick G. and Keefe, Richard S.E. and Schiffman, Susan S. and McEvoy, Joseph P.}, year={2002}, month={May}, pages={175–178} }

The incidence of taste and smell disorders will increase significantly over the coming decades due to the rapid growth in the elderly segment of the population. Furthermore, elderly individuals will likely experience taste and smell losses for a greater proportion of their lives due to the increase in life expectancy. Taste and smell disorders in the elderly present a public health challenge because they can increase the risk of malnutrition and food poisoning. Furthermore, taste and smell impairments reduce the quality of life. Deficits in taste or smell perception are a consequence of normal aging, certain disease states (especially Alzheimer's disease), medications, surgical interventions, and/or environmental exposure. Impaired taste and smell perception in the elderly can lead to poor appetite, inappropriate food choices, lower nutrient intake, and impaired nutritional status and immunity. Methods for compensating for taste and smell losses with flavor-enhanced foods is also described to improve appetite, food palatability and/or intake, increase salivary flow and immunity, and reduce oral complaints in both sick and healthy elderly.}, journal={Advances in Food and Nutrition Research}, publisher={Elsevier}, author={Schiffman, Susan S and Zervakis, Jennifer}, year={2002}, pages={247–346} }

To study this question, a unique sample of individuals (n = 33) was studied who were genetically at-risk for AD by virtue of documented multigenerational evidence of the disease (so-called multiplex families). The performance of at-risk individuals was evaluated on various smell, taste, and neuropsychological measures at baseline and 18 months later. Their performance was compared to a control group (n = 32) that was matched in age, gender, education, and race. At baseline the at-risk group performed worse than the control group on the chemosensory measures of phenethyl alcohol smell detection, smell memory, and taste memory, and on a memory measure involving recall of narrative information (Logical Memory I from the Wechsler Memory Scale- Revised). Across both sessions, the at-risk group had lower smell memory scores than the control group. At-risk status was not significantly associated with APOE status. The results of this and other studies suggest that individuals who are genetically at risk for developing AD may perform more poorly on memory and smell measures compared to those not at risk. This effect may be separate from one known genetic risk factor of AD, APOE, and supports that multiple genes are likely responsible for the disease and its associated memory and other neurocognitive symptoms.}, number={3}, journal={Neurobiology of Aging}, publisher={Elsevier BV}, author={Schiffman, S}, year={2002}, month={Jun}, pages={397–404} }

Of these, 203 were found in air samples adsorbed onto Tenax®, 112 were found in air samples adsorbed onto cotton material, and 167 different compounds were identified in the lagoon samples. The compounds identified were diverse, and included many acids, alcohols, aldehydes, amides, amines, aromatics, esters, ethers, fixed gases, halogenated hydrocarbons, hydrocarbons, ketones, nitriles, other nitrogen-containing compounds, phenols, sulfur-containing compounds, steroids, and other compounds. The vast majority of these compounds were present at concentrations below published odor and irritation thresholds. Yet human assessments indicated that odors (and irritant sensations) in the immediate vicinity of the swine houses (and even at distances beyond 1000 ft) were strong. Comparison of the findings from chemical and human assessments points to the importance of the cumulative effects of hundreds of compounds in producing odor and irritation downwind of swine operations. Many GC peaks from the samples were too small to allow identification of the compounds, but their presence may also contribute significantly to the odor and irritation. Several methodological difficulties were associated with the human odor assessments. Odorous air evaluated in the field was simultaneously collected in Tedlar® bags for evaluation in the laboratory; however, intensity ratings in the field were higher than those in the laboratory. This is due to the fact that organic dust (dried fecal material and feed) adheres to Tedlar® bags and the tubing of collection/delivery systems; therefore, only VOCs from the vapor phase (but not the dust) reach the nose of the panelists in sniffing air samples obtained in Tedlar® bags. Future collection and measurement techniques need to be developed that can evaluate odors from dust and vapor phases simultaneously in the laboratory. Dispersion models also need to be developed that account accurately for odor intensities downwind of animal operations. Finally, safety standards for odor exposures need to be determined that consider the risk of simultaneous exposure to hundreds of low level compounds.}, number={3}, journal={Agricultural and Forest Meteorology}, publisher={Elsevier BV}, author={Schiffman, Susan S and Bennett, Jeanette L and Raymer, James H}, year={2001}, month={Jun}, pages={213–240} }

These 19 medications were applied topically to the tongues of unmedicated young and elderly volunteers as well as unmedicated HIV-infected patients to measure the direct effect of the drug on taste receptors. Topical application of drugs to the apical tongue surface was used to mimic the situation in which the drug is secreted into the saliva. The main finding was that the taste qualities of these drugs were perceived as predominantly bitter, metallic, and/or sour, although several did not have a taste. Elderly subjects had higher thresholds than young subjects for one-third of the drugs that were tested. Thresholds for HIV-infected patients were statistically equivalent to young controls; however, HIV-infected patients rated the drugs as more intense at four times above the detection threshold than young subjects. Most of these drugs when applied directly to the tongue also modified the taste intensity of other tastants (e.g., NaCl, citric acid).}, number={4-5}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S and Zervakis, Jennifer and Westall, Holly L and Graham, Brevick G and Metz, Anna and Bennett, Jeanette L and Heald, Alison E}, year={2000}, month={Jun}, pages={413–424} }

The purpose of this study was to evaluate the degree of habituation to sweet-tasting foods and to determine whether there are differences in the rate of habituation between African Americans and European Americans. These two groups were compared because the prevalence of obesity and obesity-related disorders such as diabetes and hypertension is significantly higher among African Americans than among European Americans. Nine different commercial foods and beverages that differed in sweetness intensity and caloric density served as stimuli. Subjects tasted and rated each food once per minute for a 30-min period on scales related to desire for another taste of the same sample and desire for a different taste. The stimuli and portion size for each of the 30 samples were two candy bars (Ultra Slim-Fast Cocoa Almond Crunch Bar, 1/16 of a bar; Natural Nectar Peanut Butter Granola Bar, 1/16 of a bar), three beverages (Nestea Lemon Flavored Instant Tea with NutraSweet, 5 mL; Welch's Grape Juice, 5 mL; Pink Swimmingo Kool-Aid, 5 mL), two gelatin desserts (Cherry Flavored Jell-O Gelatin, 5 g; Cherry Flavored Jell-O Gelatin with NutraSweet, 5 g), one enteral nutrition drink (Vanilla Ensure Plus, 5 mL), and one pudding (Ultra Slim-Fast Chocolate Pudding, 5 g). Subjects consumed the entire portion of each sample. Habituation occurred for seven of the nine foods as judged by a decrease in the desire for another taste of the same food. The degree of habituation for European Americans and African Americans was similar except for the sweetest food (Cherry Flavored Jell-O Gelatin with NutraSweet), for which African Americans showed no habituation. The degree of habituation in both groups was unrelated to caloric density. Overall, young African Americans had a significantly greater desire for another taste of the same food than did young European Americans for seven of the nine foods, and this desire was strongly correlated with the sweetness intensity for young African Americans but not for young European Americans. Furthermore, young African Americans had a greater desire than young European Americans for a different taste for seven of nine foods. The greater desire for intense sweet tastes may be a factor in the elevated incidence of obesity and diabetes in African Americans. In addition, young African Americans had greater perceived stress in this study than did young European Americans. If African Americans use sweet taste to compensate for feelings of stress, this compensation may also contribute to weight gain.}, number={10}, journal={Nutrition}, publisher={Elsevier BV}, author={Schiffman, Susan S and Graham, Brevick G and Sattely-Miller, Elizabeth A and Peterson-Dancy, Measha}, year={2000}, month={Oct}, pages={886–893} }

In both experiments, 192 weanling gilts and barrows were allotted to 24 pens. Pens were randomly assigned to one of six dietary treatments, consisting of control (10 ppm Cu as cupric sulfate, CuSO4), 66 or 225 ppm Cu as CuSO4, or 33, 66, or 100 ppm Cu as cupric citrate (Cucitrate). An antibiotic was included in the diets for Exp. 1, but not Exp. 2. On d 28, fecal samples were randomly obtained from one pig per pen and stored at −20°C until preparation and evaluation by an odor panel. The odor panel consisted of 10 individuals, and each panelist evaluated the odor intensity, irritation intensity, and odor quality of the samples. In Exp. 1, the odor and irritation intensity of the feces were lower (P < .05) from animals consuming diets containing 225 ppm Cu as CuSO4 and 66 or 100 ppm Cu as Cu-citrate compared to the control. The odor quality of the waste from animals consuming diets containing 225 ppm Cu as CuSO4 and 66 or 100 ppm Cu as Cu-citrate was improved (P < .05) compared to the 33 ppm Cu treatment. In Exp. 2, the odor intensity of the feces of pigs receiving diets supplemented with all concentrations of Cu-citrate was lower (P < .05) than that of feces from the control animals. Irritation intensity of the feces was not affected by treatment. Odor quality of waste of pigs supplemented with 225 ppm Cu from CuSO4 and all concentrations of Cu-citrate was improved (P < .05) compared to that of waste of the control pigs. Two gilts and two barrows from each nursery pen in Exp. 1 were continued through the growing-finishing phase on their respective experimental diets. The growing-finishing phase lasted 103 d, and fecal samples were randomly obtained from one pig per pen at the completion of the phase.

The odor quality of the waste was improved (P < .05) in all animals receiving supplemental Cu. These data indicate an improvement in odor characteristics of swine waste with the supplementation of Cu.

The most frequently reported health complaints include eye, nose, and throat irritation, headache, nausea, diarrhea, hoarseness, sore throat, cough, chest tightness, nasal congestion, palpitations, shortness of breath, stress, drowsiness, and alterations in mood. Typically, these symptoms occur at the time of exposure and remit after a short period of time. However, for sensitive individuals such as asthmatic patients, exposure to odors may induce health symptoms that persist for longer periods of time as well as aggravate existing medical conditions. A workshop was held at Duke University on April 16-17, 1998 cosponsored by Duke University, the Environmental Protection Agency (EPA), and National Institute on Deafness and Other Communication Disorders (NIDCD) to assess the current state of knowledge regarding the health effects of ambient odors.

The effect of adaptation of the tongue to HIV medications on other taste stimuli with salty, sweet, sour and bitter qualities was also determined to simulate the presence of drug in the saliva. Four drugs (ritonavir, lamivudine, indinavir and didanosine) produced taste responses in the chorda tympani nerve of the gerbil at 0.625 mM and higher.

In the studies performed here, nine cardiovascular medications (labetalol HCl, captopril, diltiazem HCl, enalapril maleate, hydrochlorothiazide, propranolol HCl, mexiletine HCl, procainamide HCl, and propafenone HCl) were applied to the tongue in human volunteers to measure the direct effect of these drugs on taste receptors. The medications were applied topically to the tongue surface of both young and elderly subjects to mimic the situation in which the drug is secreted into the saliva. Detection thresholds ranged from 0.048 mM (propafenone) to 0.438 mM (procainamide). The detection thresholds of healthy elderly subjects did not significantly differ from young controls. The compounds tested had a predominantly bitter taste with other qualities as well. In addition, topical application of the medications to the tongue affected the taste of one or more taste stimuli, with medications differing in the pattern of taste effects exhibited.

All other tastes have been presumed to be combinations of these basic tastes. This psychophysical concept has been extended to electrophysiological data. That is, the neural code for each basic taste is hypothesized to be coded by a dedicated channel of neurons (the "Labeled-Line" theory); i.e., one group of neurons signals "salty" and another separate group signals "sweet." Numerous psychophysical and electrophysiological findings, however, cannot be accomodated by this quadripartite theory, which limits taste to four basic qualities and four basic neuron types. Rather, the data described in this article suggest that the range of taste is more extensive than four or five basic tastes, and that this breadth of taste quality results initially from the activation of a broad array of ion channels, receptors, and second messengers associated with taste cell membranes. These findings have implications for neural organization and provide support for the "Across-Fiber Pattern" theory in which the neural code for taste is represented by the pattern of activity across all of the neurons, i.e., neurons are not exclusively labeled for a particular sensation but cooperate with the others in the ensemble to encode taste quality.}, number={1-2}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S}, year={2000}, month={Apr}, pages={147–159} }

Na-PMP has been approved for use in confectionary/ frostings, soft candy and snack products in the USA at concentrations up to 150 p.p.m. A trained panel evaluated the effect of Na-PMP on the intensity of the following 15 sweeteners: three sugars (fructose, glucose, sucrose), three terpenoid glycosides (monoammonium glycyrrhizinate, rebaudioside-A, stevioside), two dipeptide derivatives (alitame, aspartame), two N-sulfonylamides (acesulfame-K, sodium saccharin), two polyhydric alcohols (mannitol, sorbitol), 1 dihydrochalcone (neohesperidin dihydrochalcone), one protein (thaumatin) and one sulfamate (sodium cyclamate). Sweeteners were tested at concentrations isosweet with 2.5, 5, 7.5 and 10% sucrose in mixtures with two levels of Na-PMP: 250 and 500 p.p.m. In addition, the 15 sweeteners were tested either immediately or 30 s after a pre-rinse with 500 p.p.m. Na-PMP. In mixtures, Na-PMP at both the 250 and 500 p.p.m. levels significantly blocked sweetness intensity for 12 of the 15 sweeteners. However, when Na-PMP was mixed with three of the 15 sweeteners (monoammonium glycyrrhizinate, neohesperidin dihydrochalcone and thaumatin), there was little reduction in sweetness intensity. Pre-rinsing with Na-PMP both inhibited and enhanced sweetness with the greatest enhancements found for monoammonium glycyrrhizinate, neohesperidin dihydrochalcone and thaumatin, which were not suppressed by Na-PMP in mixtures. The mixture data suggest that Na-PMP is a selective competitive inhibitor of sweet taste. The finding that pre-treatment can produce enhancement may be due to sensitization of sweetener receptors by Na-PMP.}, number={4}, journal={Chemical Senses}, publisher={Oxford University Press (OUP)}, author={Schiffman, S.

Persons who report symptoms from odors generally find problems with many different types of odorous compounds. A review of recent studies suggests that the main complaints of health symptoms from odors are eye, nose, and throat irritation, headache, and drowsiness. Sensory irritation (pungency) can be produced by a broad range of odorous volatile organic compounds from trees, flowers, foods (pepper and ginger) as well as emissions from livestock operations.

Design: Cross-sectional survey. Setting: Tertiary care university medical center clinic. Participants: A total of 207 HIV-infected patients. Main outcome measures: Chemosensory complaint score from taste and smell questionnaire and quality of life scores from the Medical Outcomes Study HIV Health Survey (MOS-HIV). Results: A total of 144 patients (70%) reported chemosensory complaints, 91 (44%) reported both taste and smell complaints, 47 (23%) reported only taste complaints, and six (3%) reported only smell complaints. Many patients complained that drugs interfered with their sense of taste, or that medications tasted bad. Higher chemosensory complaint scores were associated with a greater number of medications taken, tobacco use, and hay fever. Patients with chemosensory complaints had significantly lower scores in all domains of the MOS-HIV than those without complaints. Quality of life as measured by the MOS-HIV was lower in patients with chemosensory complaints even after controlling for number of AIDS diagnoses, number of medications, CD4 cell count, and HIV-1 viral load. Conclusions: Chemosensory complaints were common in the patient population and were associated with a poor quality of life. Medications played an important role in chemosensory complaints.

However, a series of biochemical, electrophysiological, and psychophysical studies suggest that proteinaceous receptors coupled to the G-protein/adenylate cyclase second messenger cascade mediate sweet taste for some compounds. Other second messenger systems (e.g. the phosphatidyl inositol system) as well as ion channels and non-receptor mechanisms may also be involved. There is ample evidence that multiple types of sweet receptors are required to transduce signals for the many chemical classes of compounds that taste sweet: e.g. low molecular weight carbohydrates, aminoacyl sugars, amino acids, peptides, proteins, terpenoids, chlorinated hydrocarbons, halogenated sugars, N-sulfonyl amides, sulfamates, polyketides, anilines, and ureas. Evidence for multiple receptors comes from a variety of studies including: 1) use of sweetness inhibitors (e.g. gymnemic acid or phenoxyalkanoic acid compounds), 2) electrophysiological recordings using modifiers of second messenger systems, 3) cross-adaptation studies, 4) sweetener mixtures that produce synergy, and 5) structure-activity studies combined with molecular modeling.

In this study, salivary IgA was determined by ELISA in samples of 48 persons grouped as "young" (20-30 years old) and "elderly" (60-80 years old). Unstimulated, stabilized morning and afternoon saliva was collected during 7 consecutive days. Saliva flow, total proteins, sIgA concentrations, and sIgA secretion rates were determined. The main finding was that saliva flow and sIgA secretion rate were significantly lower in the elderly than in the young. Salivary IgA secretion rate was found to be independent of total proteins secreted in all samples. There is individual variability within a particular age group.

Twenty volunteers with coffee-sensitivity were studied in a double-blind, 3 period, crossover study examining the effect of three regular (caffeinated) coffees (a coffee from the USA—“A”; a “treated” coffee from Europe—“B”; and an “untreated” coffee from Europe—“C”) before and after a high-fat test meal. The median acid contact times for coffees A, B, and C were 6.5%, 9%, and 10.5%, respectively (A vs. C, p = 0.005). Significantly fewer patients reported any symptoms with coffee A compared with coffee C (p < 0.05). Symptoms were usually more frequent and severe after the test meal. There was a trend toward fewer and less severe symptoms with the treated coffee (B) compared with its untreated counterpart (C). Our conclusions are as follows: (a) Different coffees induce variations in gastroesophageal reflux in coffee-sensitive individuals. (b) Coffee can be treated in a manner which decreases heartburn symptoms by 75% while decreasing acid contact by only 14%. (c) Gastroesophageal reflux and symptoms of coffee sensitivity increase with the concomitant ingestion of food. (d) Symptoms of dyspepsia appear to be influenced by variations in both the coffee itself and characteristics of susceptible individuals.

Damage to taste and smell receptors can impair food intake, nutritional status, and survival. The purpose of this study was to determine the effects of 11 environmental pollutants (nine insecticides and two herbicides) on electrophysiological taste responses in the gerbil. Integrated chorda tympani (CT) recordings were obtained from gerbils to a range of tastants before and after a 4-min application of 1 of 11 environmental pollutants. The taste stimuli were: sodium chloride (100 mM), calcium chloride (300 mM), magnesium chloride (100 mM), HCl (10 mM), potassium chloride (500 mM), monosodium glutamate (MSG) (50 mM), sucrose (100 mM), fructose (300 mM), sodium saccharin (10 mM), quinine HCl (30 mM), and urea (2 M). The nine insecticides included organophosphorous, carbamate, and pyrethroid insecticides. The seven organophosphorous insecticides tested were: acephate, carbofuran, chlorpyrifos, chlorpyrifos oxon, demeton, malathion, and methamidophos. The carbamate insecticide carbaryl and the pyrethroid insecticide fenvalerate were also tested. Two herbicides, paraquat and glyphosate, were tested, and dose-response curves for each of these two herbicides were also determined. All of the 11 insecticides and herbicides had an effect on some of the taste stimuli tested. Application of 10 mM methamidophos exhibited the greatest amount of suppression on the 11 taste solutions.

The pathogenesis of wasting is multifactorial and includes reduced caloric intake as a major contributing mechanism. The perceptions of taste and smell play an important role in stimulating caloric intake and in optimizing nutrient absorption through cephalic phase reflexes. The purpose of this study was to evaluate the degree of losses in taste and smell function that occur in subjects infected with HIV. Taste and smell function was evaluated in 40 HIV infected individuals and 40 healthy control subjects matched for age, sex, race, smoking behavior, and number of years of education. Chemosensory tests administered to subjects included taste and smell detection thresholds, taste and smell memory tests, taste and smell discrimination tests, and taste and smell identification tasks. Significant differences were observed between experimental and control subjects in glutamic acid taste detection threshold (p < 0.001), quinine hydrochloride taste detection threshold (p < 0.001), menthol smell detection threshold (p < 0.001) and in the taste identification task (p = 0.006). Overall the results suggest abnormalities in the peripheral and central nervous systems, and subjective distortion of taste and smell. A significant correlation was not established between CDC classification of HIV infection and taste and smell function, although trends were observed suggesting worsening function with progression of HIV disease. These results document significant taste and smell losses in HIV infected subjects which may be of clinical significance in the development or progression of HIV associated wasting.}, number={2}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Graham, Camilla S. and Graham, Brevick G. and Bartlett, John A. and Heald, Alison E. and Schiffman, Susan S.}, year={1995}, month={Aug}, pages={287–293} }

The purpose of this study was to determine the degree of adaptation of the sweet response for a variety of sweeteners in water and in the presence of two levels of tannic acid. Sweetness intensity ratings were given by a trained panel for 14 sweeteners: three sugars (fructose, glucose, sucrose), two polyhydric alcohols (mannitol, sorbitol), two terpenoid glycosides (rebaudioside-A, stevioside), two dipeptide derivatives (alitame, aspartame), one sulfamate (sodium cyclamate), one protein (thaumatin), two N-sulfonyl amides (acesulfame-K, sodium saccharin), and one dihydrochalcone (neohesperidin dihydrochalcone). Panelists were given four isointense concentrations of each sweetener by itself and in the presence of two concentrations of tannic acid. Each sweetener concentration was tasted and rated four consecutive times with a 30 s interval between each taste and a 2 min interval between each concentration. Within a taste session, a series of concentrations of a given sweetener was presented in ascending order of magnitude. Adaptation was calculated as the decrease in intensity from the first to the fourth sample. The greatest adaptation in water solutions was found for acesulfame-K, Na saccharin, rebaudioside-A, and stevioside. This was followed by the dipeptide sweeteners, alitame and aspartame. The least adaptation occurred with the sugars, polyhydric alcohols, and neohesperidin dihydrochalcone. Adaptation was greater in tannic acid solutions than in water for six sweeteners. Adaptation of sweet taste may result from the desensitization of sweetener receptors analogous to the homologous desensitization found in the beta adrenergic system.}, number={3}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S and Pecore, Suzanne D and Booth, Barbara J and Losee, Michael L and Carr, B.Thomas and Sattely-Miller, Elizabeth and Graham, Brevick G and Warwick, Zoe S}, year={1994}, month={Mar}, pages={547–559} }

Total avoidance of gliadin is the lifelong treatment for such patients. However, wheat gliadins are often present as impurities in industrial starch commonly used in the preparation of different pharmaceutical products. Therefore, some drugs might contain gliadin, which can be dangerous for sensitive patients if taken in large amounts or used permanently. The purpose of this study was to develop a sensitive, reliable assay that is specific for the detection of gliadins in pharmaceutical products. Gliadins were extracted here using sodium dodecyl sulfate rather than 70% ethyl alcohol, which has been the traditional solvent. This gliadin extract was utilized in a dot-blot assay that incorporated an antigliadin antibody developed in rabbit and labeled with peroxidase. 4-Chloro-1-naphthol was used as a peroxidase-specific substrate. Isolated wheat gliadin was used as the positive control. Dilution experiments showed that the lower level of sensitivity for the assay was in the range of 0.0045 mg/ml of gliadin, which is a concentration level lower than that suggested for a gluten-free diet. The assay developed here revealed that 71.2% of 59 prescription and nonprescription drugs tested contained gliadin in the amount detected by our dot-blot assay. The prescription drugs tested were among the top 50 most frequently dispensed in U.S. community pharmacies. The nonprescription drugs were among those that constitute the largest sales in the United States. The results showed that the simple dot-blot assay developed here can be used for pharmaceutical testing performed either by hospital laboratories or by patients themselves.}, number={1}, journal={Journal of Pediatric Gastroenterology and Nutrition}, publisher={Ovid Technologies (Wolters Kluwer Health)}, author={Miletic, Ivanka Dj. and Miletic, Vojislav D. and Sattely-Miller, Elizabeth A. and Schiffman, Susan S.}, year={1994}, month={Jul}, pages={27–33} }

This study analyzes TA binding to lipid membranes and the ensuing aggregation. The optical density of dispersions of phosphatidylcholine (PC) vesicles increased upon the addition of TA and electron micrographs showed that TA caused the vesicles to aggregate and form stacks of tightly packed disks. Solution calorimetry showed that TA bound to PC bilayers with a molar binding enthalpy of -8.3 kcal/mol and zeta potential measurements revealed that TA imparted a small negative charge to PC vesicles. Monolayer studies showed that TA bound to PC with a dissociation constant of 1.5 microM and reduced the dipole potential by up to 250 mV. Both the increase in optical density and decrease in dipole potential produced by TA could be reversed by the addition of polyvinylpyrrolidone, a compound that chelates TA by providing H-bond acceptor groups. NMR, micropipette aspiration, and x-ray diffraction experiments showed that TA incorporated into liquid crystalline PC membranes, increasing the area per lipid molecule and decreasing the bilayer thickness by 2 to 4%. 2H-NMR quadrupole splitting measurements also showed that TA associated with a PC molecule for times much less than 10(-4) s. In gel phase bilayers, TA caused the hydrocarbon chains from apposing monolayers to fully interdigitate. X-ray diffraction measurements of both gel and liquid crystalline dispersions showed that TA, at a critical concentration of about 1 mM, reduced the fluid spacing between adjacent bilayers by 8-10 A. These data place severe constraints on how TA can pack between adjacent bilayers and cause vesicles to adhere. We conclude that TA promotes vesicle aggregation by reducing the fluid spacing between bilayers by the formation of transient interbilayer bridges by inserting its digallic acid residues into the interfacial regions of adjacent bilayers and spanning the interbilayer space.}, number={6}, journal={Biophysical Journal}, publisher={Elsevier BV}, author={Simon, S.A. and Disalvo, E.A. and Gawrisch, K. and Borovyagin, V. and Toone, E. and Schiffman, S.S. and Needham, D. and McIntosh, T.J.}, year={1994}, month={Jun}, pages={1943–1958} }

Detection and recognition thresholds were determined for six bitter compounds (caffeine, denatonium benzoate, magnesium chloride, quinine hydrochloride, sucrose octaacetate, and urea) in the absence and presence of several suprathreshold concentrations of five sweeteners. The sweeteners were: sucrose, aspartame, sodium saccharin, mannitol, and sorbitol. Polycose was also tested along with the sweeteners. The degree to which bitter thresholds were affected by the addition of sweeteners was dependent on the chemical classification of the sweeteners and their concentrations. In general, the natural sweeteners, sucrose, mannitol, and sorbitol, were more effective than the noncaloric sweeteners, aspartame and sodium saccharin, in elevating the detection and recognition thresholds of the bitter compounds. A sweetness intensity approximating that of 6% sucrose (0.175 M sucrose) or greater was required to elevate thresholds. For elderly subjects, sweeteners did not significantly elevate thresholds for denatonium benzoate and sucrose octaacetate. The degree to which sorbitol and sucrose can decrease the perceived bitterness intensity of suprathreshold concentrations of the six bitter compounds was also determined. The concentrations of sweeteners and bitter compounds were selected to be of moderate to high subjective intensity. The levels of sweeteners used in the mixtures were: sucrose (none, 0.946 M, and 2.13 M) and sorbitol (none, 2.1 M, and 3.68 M).

Although chemosensory deficits cannot be reversed, previous studies have shown that the addition of intense flavors to foods can compensate for perceptual losses and improve food palatability and acceptance. In this study, the effect of sustained (3 week) flavor enhancement of typical institutional foods on the diet, health, and well being of 39 elderly (average age 84.6 SE 0.81 years) retirement-home residents was evaluated. For 3 weeks subjects ate an institutional diet (unenhanced). During another 3-week period, the same subjects ate identical foods to which intense flavors were added (enhanced). The 39 subjects were tested in two groups. For group 1 the unenhanced food period preceded the enhanced food period. For group 2, the order was reversed. Food intake was measured every weekday throughout the study, and the nutritional composition of the diet was analyzed. Biochemical measures of health status were obtained at the beginning of the study (baseline) and following both the unenhanced and enhanced periods. These measures included somatomedin-C/insulin-like growth factor I, transferrin, total T- and B-lymphocytes, and routine blood chemistries. Weight, height, midarm circumference, and triceps skinfold thickness were also measured. Handgrip strength and pinch strength were measured in group 1. Three major findings emerged from this study: 1) elderly persons ate more food when it was flavor enhanced, 2) consumption of flavor-enhanced food was associated with improved immune function that was not attributable to altered nutrient intake or biochemical status, and 3) improved grip strength in both hands was evident after 3 weeks' consumption of flavor-enhanced foods.}, number={2}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S. and Warwick, Zoe S.}, year={1993}, month={Jan}, pages={395–402} }

Aspartame and vanilla were used to augment meal palatability, yielding four isocaloric liquid meals: bland-FAT, tasty-FAT, bland-CHO, tasty-CHO. Normal-weight, nondieting young adults consumed each of the meals for breakfast on separate days. The main finding was that tasty versions of high-FAT and high-CHO meals were more satiating than nutritionally identical bland meals, as indicated by a greater decrease in hunger ratings following the tasty meals. Changes in blood glucose and FFA were related to meal nutrient composition, but not to meal sensory properties. High-CHO meals tended to be more satiating than high-FAT meals. Consumption of each of the meals produced a similar decrease in pleasantness ratings of food-related tastes. Intake of carbohydrates was significantly higher at a self-selected lunch 5.25 h following a tasty breakfast. These findings indicate that hunger is decreased to a greater extent by meals flavored with aspartame and vanilla relative to nutritionally identical, unflavored meals.

Citric acid solutions were delivered to a closed, spatially-matched (each test site was 43 mm2) flow chamber attached to the surface of the anterior tongue in 84 subjects. A two-alternative forced choice, modified staircase procedure was used to derive a detection threshold value for citric acid. The same session also included a visual analog rating procedure to scale the taste intensity judgement of five concentrations of citric acid. The taste buds within the chamber were distinguished by methylene blue stain and recorded by videomicroscopy. The sip-and-spit method was used to contrast the spatially-matched condition with whole mouth stimulation. We found that detection threshold values were inversely related to the number of fungiform taste buds, independent of gender or age. Whole-mouth threshold values determined for each subject were always well below the spatially-matched threshold values. In addition, the data demonstrated that subjects were able to scale the dynamic range of citric acid solutions. However, y-intercept approached zero intensity as the number of fungiform papillae decreased. The observed differences in citric acid sensitivity and fungiform taste bud density indicated that taste performance on the anterior tongue in humans varies, in part, with the number of taste buds.}, number={5}, journal={Chemical Senses}, publisher={Oxford University Press (OUP)}, author={Zuniga, John R. and Davis, Steve H. and Englehardt, Robert A. and Miller, Inglis J., Jr and Schiffrman, Susan S. and Phillips, Ceib}, year={1993}, pages={449–460} }

Electrophysiological recordings were made here from the whole chorda tympani nerve in gerbil to understand the interactive effect of astringent-tasting molecules with a broad spectrum of tastants including mono- and divalent salts, bitter compounds, acids, and sweeteners. The astringent tasting compounds were tannic acid (24 mM at pH's 2.9 and 5.5), aluminum ammonium sulfate (30 mM), aluminum potassium sulfate (10 mM) and gallic acid (30 mM). Hydrochloric acid (1 mM, pH 2.9) was also tested to control for acidity, since aqueous solutions of astringent-tasting compounds are acidic. Adaptation of the tongue to tannic acid (24 mM) at both pH 2.9 and 5.5 markedly inhibited responses elicited by salts, acids, sweeteners, and bitter-tasting compounds. The degree of the inhibition at these two pH values is about the same which suggests that tannic acid itself (as opposed to acidity) may produce this inhibition. Chorda tympani responses to sweeteners were completely suppressed by tannic acid; responses to KCl, NH4Cl, and urea were the least suppressed. The aluminum salts also inhibited the chorda tympani responses to all stimuli tested. Gallic acid, which is weakly astringent, had minimal effects on the chorda tympani responses to the test compounds. These data suggest that both tannic acid and the aluminum salts inhibit a variety of transport pathways and receptors in taste cells for a broad spectrum of tastants. The inhibition of some of these pathways may contribute to the astringent taste sensation.}, number={1}, journal={Brain Research}, publisher={Elsevier BV}, author={Schiffman, Susan S. and Suggs, Mark S. and Simon, Sidney A.}, year={1992}, month={Nov}, pages={1–11} }

Lowering the pH from 7.4 to 3.2 decreases ion transport, as measured by the short-circuit current (Isc), when the dorsal surface of the tongue is bathed in 0.5 M NaCl and increases Isc when it is bathed in 0.05 M NaCl, tannic acid (0.1 M) inhibits Isc at both pH 3.2 and 7.4. At 0.05 M NaCl, pH 7.4 tannic acid also inhibits Isc. Thus, inhibition of Isc by tannic acid does not depend upon the pH, meaning that the reduction in transport arises from tannic acid. In the presence of NaCl (at both 0.05 and 0.5 M NaCl), 0.1 M AlK (SO4)2 or 0.1 M AlNH4(SO4)2 also inhibit Isc. For these salts, the decrease in Isc arises from the aluminum ion and not from K+, NH4+, or SO(4-)-. Other less astringent compounds (gallic and tartaric acids) had only slight effects on Isc. The main findings of this study are that both tannic acid and the aluminum salts inhibited ion transport, likely Na+ influx, via amiloride-inhibitable channels in isolated lingual epithelia. Inhibition of such Na+ channels may contribute to astringent taste.}, number={1}, journal={Pharmacology Biochemistry and Behavior}, publisher={Elsevier BV}, author={Simon, S.A. and Hall, W.L. and Schiffman, S.S.}, year={1992}, month={Sep}, pages={271–283} }

There is controversy, however, whether "astringency," with its associated puckering and drying sensations, is a fundamental taste quality or is a tactile sensation. To address this issue, electrophysiological recordings were made from the gerbil chorda tympani nerve and the rat lingual nerve. The chorda tympani nerve transmits taste information from the anterior 2/3 of the tongue, whereas the lingual nerve transmits tactile, thermal and pain sensations from the anterior 2/3 of the tongue. The astringent compounds tested were: tannic acid, tartaric acid, gallic acid, aluminum ammonium sulfate and aluminum potassium sulfate. Tannic acid, tartaric acid, and gallic acids were tested at concentrations up to 120 mM over a pH range from approximately 2 to 6. The aluminum salts were tested at concentrations up to 160 mM only at low pH's. All compounds rapidly (and at lower concentrations, reversibly) stimulate the chorda tympani nerve in a concentration-dependent manner at all pH's tested. The rapidity and reversibility of the chorda tympani responses suggest that astringent-tasting compounds interact directly with taste cells rather than indirectly by precipitating salivary proteins. At pH 6, tannic acid, tartaric acid, and gallic acid all elicit robust chorda tympani responses, implying that the ionized forms of these compounds produce taste sensations. None of these compounds stimulate lingual nerves over the same concentration and pH ranges used in the chorda tympani experiments.(ABSTRACT TRUNCATED AT 250 WORDS)}, number={1}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S. and Suggs, Mark S. and Sostman, L. and Simon, Sidney A.}, year={1992}, month={Jan}, pages={55–63} }

An overview of 40 animal studies which compared growth on high-fat (HF) and high-carbohydrate (HC) solid/powdered diets indicated that the HF diet elicited greater weight gain in 33 out of 40 studies. Enhanced growth on the HF diet was often, but not exclusively, attributable to greater caloric intake. Additional evidence for the growth-enhancing effect of HF diets emerges from "diet option" and "supermarket" feeding studies in rats, and experimental and epidemiological studies in humans. Three principal factors that contribute to the different responses to HF and HC diets are (a) caloric density, (b) sensory properties and palatability, and (c) postabsorptive processing. It is concluded that both calorie intake and metabolic energy expenditure are biased towards weight gain when a HF diet is consumed, and that the high caloric density of high-fat diets plays a primary role in weight gain. Humans may be biologically predisposed to gain weight when a HF diet is consumed.}, number={4}, journal={Neuroscience & Biobehavioral Reviews}, publisher={Elsevier BV}, author={Warwick, Zoe S. and Schiffman, Susan S.}, year={1992}, month={Jan}, pages={585–596} }

Lab chow was diluted with cellulose to produce three foods that differed in caloric density while having identical nutritional composition. High-density (HD) food contained 3.33 kcal/g; mid-density (MD) food contained 2.64 kcal/g; low-density (LD) food contained 2.06 kcal/g. These foods were flavored with nonnutritive powders and were used in four different feeding regimens. For 15 days, group FLAV ate MD with one of 3 flavors added daily in a 3-day rotation. Groups DENS and NOVEL rotated daily among LD, HD, and MD. One of three flavors was added to each food. For group DENS, LD always contained one flavor, MD always contained another flavor, and HD always contained the third flavor. For group NOVEL, flavor-density pairings were not consistent. A control group, CONT, ate only MD with a single flavor. Weight gain was greatest in group NOVEL. Neither density variety nor flavor variety alone enhanced weight gain relative to control. In a subsequent experiment, group NOVEL did not display a preference for a glucose-paired flavor. These results suggest that reduced orosensory control of energy balance induced by uncoupling of flavor-calorie relationships contributes to weight gain.}, number={3}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Warwick, Zoe S. and Schiffman, Susan S.}, year={1991}, month={Sep}, pages={465–470} }

The purpose of the present study was to determine if greater inhibition could be achieved with three potent amiloride analogs that are specific for the epithelial Na+ channel: phenamil, 2',4'-dimethylbenzamil, and 3',4'-dichlorobenzamil. Application of phenamil (100 microM) to the anterior tongue blocked integrated responses to NaCl from the chorda tympani nerve by 98.04%, but had no significant effect on sucrose or NH4Cl. This finding suggests that the epithelial Na+ channel alone transduces the taste of NaCl in gerbil. The residual 30-40% of the response that is not blocked by amiloride can simply be explained by the fact that amiloride is less potent than phenamil. On average, 100 microM phenamil blocked responses to Na+ salts with a variety of anions by 94.2%; 100 microM 2',4'-dimethylbenzamil, by 89.83%; and 100 microM 3',4'-dichlorobenzamil, by 72.56%.

The pattern of responses from the chorda tympani nerve indicates that the taste of NaCl is almost totally accounted for by the epithelial Na+ channel. Phenamil, an amiloride analog which specifically blocks the epithelial Na+ channel at low concentrations, suppressed the taste responses to 0.03 M NaCl by 97%. The pattern of responses also indicates that the Na+/H+ antiporter and the Na+/Ca2+ exchanger do not mediate salt taste in the gerbil. None of the amiloride analogs blocked taste responses to CaCl2, sucrose, or glutamic acid.

This suggests that the vagus nerve is the primary mediator of the cephalic phase response to tastants. There were marked individual differences among dogs in the responses to the ten tastants that were tested.

At hyposmotic concentrations of KCl, potassium ions enter the mucosal membrane through a K+ pathway that is inhibited by 4-aminopyridine and exit at the serosal membrane through a K+ pathway that is inhibited by BaCl2. The inhibition of sodium transport by amiloride and potassium transport by 4-aminopyridine is consistent with previously published electrophysiological recordings from the chorda tympani nerve bundle (CT) and recordings from nucleus of the solitary tract (NST) obtained here. The responses to NaCl are greater than the responses to KCl at equimolar concentrations over the entire concentration range both in epithelial and neural measurements. At hyposmotic concentrations of NaCl the epithelial responses include inward sodium and outward chloride components.

It emphasizes that no sweet receptor has ever been isolated nor are the physicochemical properties of molecules necessary to initiate a sweet sensation well understood. The most prominent theory to date is that a pair of simultaneous hydrogen bonds separated by approximately 3 Å is a necessary condition for sweetness. The investigations that shed light on the nature of sweet receptors derive from a range of disciplines including organic chemistry, biochemistry, neurophysiology, psychology, biophysics, and medicinal chemistry. The chapter discusses the following topics—(1) the chemical structure of sweeteners; (2) biochemical approaches to understanding sweet receptors; (3) the electrophysiological and behavioral approaches in animals; (4) the psychophysical studies in humans including data implicating sodium transport and adenosine receptors in sweet taste; and (5) computer-assisted molecular design—a new approach to design sweeteners.}, journal={The Receptors}, publisher={Elsevier}, author={Schiffman, Susan S. and Hopfinger, Anton J. and Mazur, Robert H.}, year={1986}, pages={315–377} }

The artificial sweetener acesulfam-K, which has a bitter component, was potentiated the most by MX, i.e., approximately 100%. This increase in perceived intensity for acesulfam-K occurred at 10−5 M MX, a concentration known to inhibit adenosine receptors but below that required to inhibit phosphodiesterase.

For example, some enantiomer pairs such as L- and D-serine and L- and D-alanine exhibit similar sweet qualities. Other enantiomer pairs taste quite different from one another, such as L-proline which has a sweet component and D-proline which is bitter. The rank order of the threshold values for the D-forms tends to parallel those for the L-forms; the rank order correlation (Spearman's rho) is 0.87. However, several statistically significant threshold changes were found. Two amino acids with aromatic side chains, tryptophan and phenylalanine, have greatly reduced thresholds in the D-form while asparagine and aspartic acid, along with proline, have considerably higher thresholds in the D-form. In general, it was found that whenever a marked taste difference exists, there is a trend toward a relatively large difference in threshold values between the enantiomers. It was not found, however, that a large difference in threshold was always accompanied by a significant quality difference, or that the particular taste quality of either of the pair was a predictor of the magnitude of the threshold ratio or of which of the two forms had the highest threshold.}, number={1}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, S and Sennewald, K and Gagnon, J}, year={1981}, month={Jul}, pages={51–59} }

The largest relative decline in slope was found for those stimuli with the greatest number of possible AH-B types, suggesting that the possibilities for concerted intermolecular hydrogen bonding may decline with age.

Fourteen stimuli, seven artificial sweeteners varying widely in chemical structure as well as seven sugars, were cross adapted with one another. When a sugar was employed as the adapting stimulus, a consistent reduction in the intensity of the test solution's sweetness was found. However, the result of the cross adaptation when the adapting stimulus was an artificial sweetener was unpredictable; it led not only to a reduction but, in some cases, to an enhancement or no change in the test solution's intensity, depending on its identity. In previous investigations, enhancements have been explained through the existence of a water taste. Since this explanation is insufficient to account for the enhancement effects found in this study, it appears that cross adaptation does not always occur between sweet-tasting compounds.

A multidimensional scaling procedure, INDSCAL, was applied to the similarity measurements, yielding a common two-dimensional space in which flavors rated similar in odor were arranged close to one another in the space; flavors judged dissimilar were located distant from one another. INDSCAL is an individual difference model which provides weights for each subject on each of the dimensions of the common multidimensional space. The weights as well as the arrangements of flavors in multidimensional spaces for individual subjects indicated that the renal patients had sharply reduced ability to judge qualitative odor differences between food flavors. Hedonic ratings were obtained for all subjects on the 14 flavors as well. The direction of preference was similar for both renal patients and controls, with the odor of fruits preferred over meats. However, the median hedonic ratings for the two groups, renals and controls, revealed that renal patients rated thirteen of the fourteen odors more unpleasant than the controls.}, number={2}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan S. and Nash, Michael L. and Dackis, Charles}, year={1978}, month={Aug}, pages={239–242} }

The relationships between the stimuli in the two resultant spaces were quite similar. Since the structure of the space based on similarity judgments was more stable over subjects and seemed to represent more completely the tastes of the stimuli, it was considered more appropriate as a gustatory model. Using the semantic differential descriptions as well as physical continua to designate useful dimensions, it was found that the similarity space based on equi-intensive gustatory stimuli could be accurately represented by three criteria: relative goodness or badness of the taste of the stimuli, molecular weight, and departure of the stimuli from the neutral pH of 7. This model, specific to the concentrations used, shows similarities to previous psychophysical models, especially Henning's, as well as models of stimulus relationships based on neural gustatory data.}, number={4}, journal={Physiology & Behavior}, publisher={Elsevier BV}, author={Schiffman, Susan Stolte and Erickson, Robert P.}, year={1971}, month={Oct}, pages={617–633} }
