This experiment evaluated the effects of dietary normal oleic extruded expelled (NO-EE), normal oleic full-fat (NO-FF), or HO-FF SBM on live performance, carcass and parts yield, and breast fatty acid composition. Diets were formulated to be isoenergetic and isonitrogenous. A total of 540 Ross-708 male broilers were raised on floor pens with 18 broilers/pen and ten replicates/treatment. Data were analyzed in a completely randomized design. Chickens were fed with a starter (0 – 14 d), grower (15 – 35 d), or a finisher diet (36 – 47 d) up to 47 d. Chickens were weighed at 7, 14, 35, and 47 d. At 48 d, four broilers per pen were processed. Breast samples were collected and evaluated for quality and fatty acid content. Broilers fed diets with NO-EE were heavier (P < 0.05) than chickens fed diets with full-fat SBM (NO-FF and HO-FF) at d 7, 14, 35 while feed conversion ratio (FCR) of NO-EE was best (P < 0.05) at 7 d and 47 d. Carcass yield was also higher for broilers fed NO-EE than the other treatments. Diet did not affect parts yield, breast meat color, cooking, drip loss, white stripping, or SM quality parameters. More breast fillets without wooden breast (score 1) were observed (P < 0.05) for NO-FF than the other two treatments. The breast meat fatty acid profile (g fatty acid/ 100 g of all fatty acids) was significantly affected (P < 0.001) by diet. Broilers fed the HO-FF SBM diet had 54 to 86% more oleic acid, 72.5% to 2.2 times less linoleic acid, and reduced stearic and palmitic acid levels in the breast meat than NO-FF and NO-EE. In conclusion, feeding HO-FF to broilers enriched the oleic acid content of their breast meat while reducing the saturated fatty acid content relative to the NO-FF and NO-EE treatment groups.}, number={3}, journal={POULTRY SCIENCE}, author={Ali, Muhammad and Joseph, Michael and Alfaro-Wisaquillo, Maria Camila and Quintana-Ospina, Gustavo Adolfo and Patino, Danny and Vu, Thien and Dean, Lisa L. and Fallen, Ben and Mian, Rouf and Taliercio, Earl and et al.}, year={2024}, month={Mar} } @article{maharjan_rahimi_harding_vu_malheiros_oviedo-rondon_mian_joseph_dean_anderson_et al._2023, title={Effects of full-fat high-oleic soybean meal in layer diets on nutrient digestibility and egg quality parameters of a white laying hen strain}, volume={102}, ISSN={["1525-3171"]}, url={https://doi.org/10.1016/j.psj.2023.102486}, DOI={10.1016/j.psj.2023.102486}, abstractNote={This study was conducted to understand the impact of including full fat high-oleic soybean meal in layer hen diets on nutrient digestibility and added nutritional value in eggs. Forty-eight layers (∼36 wk old) were randomly assigned to one of 4 isonitrogenous (18.5% crude protein) treatment diets with 12 replicate birds per treatment in a 3-wk study. Treatments were 1) solvent extracted defatted soybean meal + corn diet, 2) dry extruded defatted soybean meal + corn, 3) full-fat soybean meal + corn, 4) high-oleic full-fat soybean meal + corn diet. Apparent ileal digestibility of crude fat (CF) and crude protein (CP) were determined using celite (∼2%) as an indigestible marker. Tibia strength and egg quality parameters (egg weight, shell strength, Haugh unit, shell color, and yolk color) were recorded during the study. Fatty acid profiles, including the monounsaturated fatty acid, oleic acid (C18:1, cis), in eggs and adipogenic tissue (liver, muscle, and fat pad) were measured using gas chromatography (GC-FID). Digestibility values of CF ranged from 71 to 84% and CP varied from 67 to 72% for treatment diets, with treatment mean values being no different (P > 0.05) between treatment diets. No differences between treatment diets in tibia strength or egg quality parameters (egg weight, shell strength, and Haugh unit) were observed (P > 0.05) except for yolk color. Similarly, there were no differences in the total lipids in egg yolk (P > 0.05) between treatment diets. However, oleic acid percentage of total lipid in egg and tissue was significantly higher (P < 0.001) in hens given the high-oleic full-fat soybean meal diet than in other treatment groups. No difference was observed in oleic acid percentage of total lipid in egg between the other 3 treatment diets (P > 0.05).

Food manufacturers and consumers have expressed interest in superior flavor experiences suggesting that flavor attributes should play a more prominent role in selection. Flavor attributes were evaluated among a subset of the North Carolina State University (NCSU) peanut germplasm collection to simplify flavor analysis and selection, confirm a recent lack of progress in flavor improvement and identify new sources of flavor improvement in Virginia‐type peanut (Arachis hypogaea L.). Multivariate and principal component analysis identified 11 flavor attributes and five principal components that should facilitate selection of improved peanut flavor. Analysis of historical variety trial data identified a significant deterioration in the roast peanut flavor and a modest improvement in other critical flavor attributes over the last 20 yr.

Utilization of cellobiose and gentiobiose by lactic acid bacteria (LAB) was tested in fermented cucumber juice medium (FCJM), a model system for the bioconversion and postfermentation lacking glucose and fructose. Changes in the fermentation metabolites were followed using HPLC and pH measurements as a function of time. The disaccharides were utilized by L. plantarum, L. pentosus, and L. buchneri in FCJM at pH 4.7 ± 0.1, representative of the active fermentation period, and converted to lactic acid. The disaccharides were not utilized in FCJM at pH 3.7 ± 0.1, representative of the end of fermentation. While L. brevis was unable to utilize cellobiose efficiently in FCJM, they were able to remove gentiobiose at pH 4.7 ± 0.1. Some strain level differences in cellobiose utilization were observed. It is concluded that the disaccharides are absent in the fresh cucumber and the typical fermentation. The LAB prevalent in the bioconversion utilizes cellobiose and gentiobiose, if available, at pH 4.7 ± 0.1.

The goal of this study was to identify the mechanisms of resistance by examining the role of plant volatile organic compounds (VOCs) and free amino acids (FAAs) among 16 soybean varieties. Choice and no-choice cage experiments identified several soybean varieties that demonstrated antixenosis as well as antibiosis. However, resistance varied over time in certain soybean varieties, such as N02-7002 and PI567352B. Mean nymph number from choice experiments had positive correlations with the FAAs asparagine, tryptophan, alanine, phenylanaline, and serine; negative correlation with leucine and threonine. Four plant volatiles, hexanal, 2-pentylfuran, beta-cyclocitral, and cis-9-hexadecenal, were positively correlated with subsequent nymph development, whereas n-hexadecenoic acid was negatively correlated with nymph number only, in adult choice cage experiments. This study contributes to understanding the mechanisms of HPR through associations with plant VOCs and FAAs in relation to M. cribraria development and provides useful knowledge for developing soybean varieties for M. cribraria management.}, number={4}, journal={Environmental Entomology}, publisher={Oxford University Press (OUP)}, author={Lahiri, S and Reisig, D D and Dean, Lisa L and Reay-Jones, F P F and Greene, J K and Carter, T E, Jr and Mian, R and Fallen, B D}, editor={Naranjo, StevenEditor}, year={2020}, month={Jul}, pages={876–885} } @article{klevorn_dean_johanningsmeier_2019, title={Metabolite Profiles of Raw Peanut Seeds Reveal Differences between Market-Types}, volume={84}, ISSN={["1750-3841"]}, DOI={10.1111/1750-3841.14450}, abstractNote={AbstractPeanuts (Arachis hypogaea L.) are prized for their flavor and popular worldwide as food or as food ingredients. The raw peanut seed contains the precursor compounds to roasted peanut flavor and has the potential to be manipulated through traditional breeding methods. However, little is known about the metabolome of the raw seeds. Comprehensive metabolite profiles of both raw runner and Virginia‐type peanuts were determined. Using a system incorporating several methodologies including (RP)/UPLC‐MS/MS and HILIC/UPLC‐MS/MS, along with quantitation of fatty acids, free amino acids, and tocopherols, 365 metabolites were identified and of these, 52 were significantly different between market types (P < 0.05). Higher levels of gamma‐glutamylalanine, oxylipins, purine metabolites, and alpha‐ketoglutarate derived members of the glutamate family of amino acids defined the Virginia‐type, while runner‐type peanuts were differentiated by their ethylmalonate and eicosenoate content. This study presents a comprehensive analysis of the raw peanut seed, providing knowledge of the range of small molecules present in peanuts. The new information presented here will enable future research for peanut quality improvement.Practical ApplicationPeanuts are widely used as snack foods and as food ingredients. Knowledge of the secondary metabolite compounds in raw peanuts is needed to determine their importance in peanut flavor and nutritional quality. This report used a nontargeted analytical approach for the identification of these types of compounds in peanuts for the first time. These data were supplemented with quantitative analysis of free amino acids and tocopherols and discussed as potential flavor precursors and health promoting compounds.}, number={3}, journal={JOURNAL OF FOOD SCIENCE}, author={Klevorn, Claire M. and Dean, Lisa L. and Johanningsmeier, Suzanne D.}, year={2019}, month={Mar}, pages={397–405} } @article{christman_dean_allen_godinez_toomer_2019, title={Peanut skin phenolic extract attenuates hyperglycemic responses in vivo and in vitro}, volume={14}, ISSN={["1932-6203"]}, DOI={10.1371/journal.pone.0214591}, abstractNote={Diabetes affects at least 285 million people globally, and this number continues to increase. Clinical complications include impaired glucose metabolism, hyperglycemia, dyslipidemia, atherosclerosis and non-alcoholic fatty liver disease. Evidence has shown that natural phenolics play a protective effect on both the development and management of type 2 diabetes. This study evaluated effects of the extract from peanut skins containing polyphenols on induced- hyperglycemia using in vivo and in vitro methods. A human hepatocellular liver carcinoma cell line (HepG2) was used to investigate the effect of the peanut skin extract on cell viability after exposure to high glucose concentrations. In vivo, the effect of peanut skin extract on an oral glucose tolerance was investigated in human subjects. Fifteen participants aged 21–32 underwent an oral glucose tolerance test with five treatments: 1) 50-gram glucose solution (reference); 2). 50-gram glucose solution, followed by 12 mg of vegi-capsulated maltodextrin; 3) 50-gram glucose solution, followed by 120 mg of vegi-capsulated maltodextrin-encapsulated peanut skin extract; 4). 50-gram glucose solution, followed by 28 grams of unfortified coated peanuts; 5) 50-gram glucose solution, followed by 28 grams of chili lime coated peanuts fortified with encapsulated peanut skin extract. Glucose levels were measured using a continuous monitor. Peanut skin extract was found to attenuate the decrease in cell viability in high glucose treated HepG2 cells, showing a protective effect against hyperglycemia induced cell death. No difference in the glycemic response area under the curve between any treatments using the tolerance test, but the treatment of the peanut skin extract with the glucose reference resulted in a significantly lower peak blood glucose response at 45 minutes, indicating that it was effective at reducing the glycemic response. The present study shows that the phenolic extract of peanut skins has an antidiabetic effect, further confirming their value as a functional food ingredient.}, number={3}, journal={PLOS ONE}, author={Christman, Lindsey M. and Dean, Lisa L. and Allen, Jonathan C. and Godinez, Sofia Feng and Toomer, Ondulla T.}, year={2019}, month={Mar} } @article{eickholt_carter_taliercio_dickey_dean_delheimer_li_2019, title={Registration of USDA-Max x Soja Core Set-1: Recovering 99% of Wild Soybean Genome from PI 366122 in 17 Agronomic Interspecific Germplasm Lines}, volume={13}, ISSN={["1940-3496"]}, DOI={10.3198/jpr2017.09.0059crg}, abstractNote={USDA‐Max × Soja Core Set‐1 (USDA‐MxS‐CS1‐1 to USDA‐MxS‐CS1‐17 [Reg.

Samples were analyzed for percent fat, percent solids, total protein, lactose, amino acids, and thiamine.Results:Percent fat, percent solids, and lactose were similar between raw, HP, and SS samples. Total protein was statistically increased in SS samples when compared to raw (P = 0.005) and HP (P < 0.001) samples, but protein differences were not clinically relevant (raw = 15.1 mg/mL, HP = 14.8 mg/mL, and SS = 15.8 mg/mL). Lysine was the only amino acid impacted by processing, and its destruction increased as heat increased (raw = 0.85 mg/100 mL, HP = 0.77 mg/100 mL, SS = 0.68 mg/100 mL). Total thiamine was significantly decreased in SS samples (0.14 mg/L; P < 0.01) when compared with raw samples (0.24 mg/L) and HP samples (0.26 mg/L).Conclusions:Macronutrient content is relatively unaffected by processing; Holder pasteurization and retort processing maintain similar fat, lactose, and total protein levels. Lysine and thiamine were significantly decreased by retort processing, but not by Holder pasteurization.

Thermal modifications of the epidermal and parenchyma cells were observed in the scanning electron microscopic images for processed peanuts, compared to raw peanuts. Peanut microstructure was most extensively damaged by blister frying, followed by deep frying, and then dry roasting. The moisture content decreased with increased surface color, due to more moisture loss with longer heat processing time. For light roasting, blister fried peanuts had significantly higher moisture contents than the deep fried and dry roasted peanuts, while for medium and dark roasting, blister fried had lower moistures than the other two. Descriptive sensory analysis was able to distinguish the flavor and texture profiles of peanuts prepared by different roasting methods. In storage testing throughout 16 weeks, peroxide value measurements indicated the blister fried peanuts had the longest shelf life, followed by the dry roasted, and then the deep fried.

The leaves from the peanut plants of the cultivated variety, Bailey and the perennial varieties, Arblick, Arbrook, and Amarillo were freeze dried, essential oils were extracted by distillation and the chemical compositions were determined using gas chromatography and gas chromatography-mass spectrometry. Oil yield from the A. hypogaea leaves was 0.0063 % (w/w). The major components were 1-octen-3-ol (12.4 %), heneicosane (11.7 %), nonanal (10.9 %), 4-vinylguaiacol (6.4 %) and phytol (7.4 %). The yield from A. glabrata and A. pintoi leaves ranged from 0.0044 % to 0.0061 % (w/w) with the major components in common among the three varieties tested 1-octen-3-ol (40.5-44.9 %), β-linalool (5.0-8.9 %) and 4-vinylguaiacol (1.4-8.6 %).}, number={3}, journal={JOURNAL OF ESSENTIAL OIL BEARING PLANTS}, author={Constanza, Karen and Tallury, Shyamalrau and Whaley, Jeffrey and Sanders, Timothy and Dean, Lisa}, year={2015}, month={May}, pages={605–612} } @article{yang_meng_breidt_dean_arritt_2015, title={Effects of Acetic Acid and Arginine on pH Elevation and Growth of Bacillus licheniformis in an Acidified Cucumber Juice Medium}, volume={78}, ISSN={["1944-9097"]}, DOI={10.4315/0362-028x.jfp-14-478}, abstractNote={Bacillus licheniformis has been shown to cause pH elevation in tomato products having an initial pH below 4.6 and metabiotic effects that can lead to the growth of pathogenic bacteria. Because of this, the organism poses a potential risk to acidified vegetable products; however, little is known about the growth and metabolism of this organism in these products. To clarify the mechanisms of pH change and growth of B. licheniformis in vegetable broth under acidic conditions, a cucumber juice medium representative of a noninhibitory vegetable broth was used to monitor changes in pH, cell growth, and catabolism of sugars and amino acids. For initial pH values between pH 4.1 to 6.0, pH changes resulted from both fermentation of sugar (lowering pH) and ammonia production (raising pH). An initial pH elevation occurred, with starting pH values of pH 4.1 to 4.9 under both aerobic and anaerobic conditions, and was apparently mediated by the arginine deiminase reaction of B. licheniformis. This initial pH elevation was prevented if 5 mM or greater acetic acid was present in the brine at the same pH. In laboratory media, under favorable conditions for growth, data indicated that growth of the organism was inhibited at pH 4.6 with protonated acetic acid concentrations of 10 to 20 mM, corresponding to 25 to 50 mM total acetic acid; however, growth inhibition required greater than 300 mM citric acid (10-fold excess of the amount in processed tomato products) products under similar conditions. The data indicate that growth and pH increase by B. licheniformis may be inhibited by the acetic acid present in most commercial acidified vegetable products but not by the citric acid in many tomato products.}, number={4}, journal={JOURNAL OF FOOD PROTECTION}, author={Yang, Zhenquan and Meng, Xia and Breidt, Frederick, Jr. and Dean, Lisa L. and Arritt, Fletcher M.}, year={2015}, month={Apr}, pages={728–737} } @article{iasmin_dean_ducoste_2016, title={Quantifying fat, oil, and grease deposit formation kinetics}, volume={88}, ISSN={["0043-1354"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-84947483809&partnerID=MN8TOARS}, DOI={10.1016/j.watres.2015.11.009}, abstractNote={Fat, oil, and grease (FOG) deposits formed in sanitary sewers are calcium-based saponified solids that are responsible for a significant number of nationwide sanitary sewer overflows (SSOs) across United States.

The results of this study displayed quick reactions of a fraction of fats with calcium ions to form calcium based saponified solids. Results further showed that increased palmitic fatty acid content in source fats, the magnitude of the pH, and temperature significantly affect the FOG deposit formation and saponification rates. The experimental data of the kinetics were compared with two empirical models: a) Cotte saponification model and b) Foubert crystallization model and a mass-action based mechanistic model that included alkali driven hydrolysis of triglycerides. Results showed that the mass action based mechanistic model was able to predict changes in the rate of formation of saponified solids under the different experimental conditions compared to both empirical models. The mass-action based saponification model also revealed that the hydrolysis of Beef Tallow was slower compared to liquid Canola fat resulting in smaller quantities of saponified solids.

The objective of this study was to quantify the factors that may affect the formation of FOG deposits and their chemical and rheological properties. These factors included the types of fats used in FSEs, environmental conditions (i.e. pH and temperature), and the source of calcium in sewer systems. The results of this study showed that calcium content in the calcium based salts seemed to depend on the solubility limit of the calcium source and influenced by pH and temperature conditions. The fatty acid profile of the calcium-based fatty acid salts produced under alkali driven hydrolysis were identical to the profile of the fat source and did not match the profile of field FOG deposits, which displayed a high fraction of palmitic, a long chain saturated fatty acid. It is hypothesized that selective microbial metabolism of fats and/or biologically induced hydrogenation may contribute to the FOG deposit makeup in sewer system. Therefore, selective removal of palmitic in pretreatment processes may be necessary prior to the discharge of FSE wastes into the sewer collection system.}, journal={WATER RESEARCH}, author={Iasmin, Mahbuba and Dean, Lisa O. and Lappi, Simon E. and Ducoste, Joel J.}, year={2014}, month={Feb}, pages={92–102} } @article{isleib_milla-lewis_pattee_copeland_zuleta_shew_hollowell_sanders_dean_hendrix_et al._2015, title={Registration of ‘Sugg’ peanut}, volume={9}, ISSN={["1940-3496"]}, DOI={10.3198/jpr2013.09.0059crc}, abstractNote={‘Sugg’ (Reg.

We report the first formation of FOG deposits on a concrete surface under laboratory conditions that mimic the formation of deposits in sewer systems. Results showed that calcium, the dominant metal in FOG deposits, can be released from concrete surfaces under low pH conditions and contribute to the formation process. Small amounts of additional oil to grease interceptor effluent substantially facilitated the air/water or pipe surface/water interfacial reaction between free fatty acids and calcium to produce surface FOG deposits. Tests of different fatty acids revealed that more viscous FOG deposit solids were formed on concrete surfaces, and concrete corrosion was accelerated, in the presence of unsaturated FFAs versus saturated FFAs.

Standard industry practice is to roast peanuts to a specific surface color (Hunter L‐value) for a given application; however, equivalent surface colors can be attained using different roast temperature/time combinations, which could affect product quality. To investigate this potential, runner peanuts from a single lot were systematically roasted using 5 roast temperatures (147, 157, 167, 177, and 187 °C) and to Hunter L‐values of 53 ± 1, 48.5 ± 1, and 43 ± 1, corresponding to light, medium, and dark roasts, respectively. Moisture contents (MC) ranged from 0.41% to 1.70% after roasting. At equivalent roast temperatures, MC decreased as peanuts became darker; however, for a given color, MC decreased with decreasing roast temperature due to longer roast times required for specified color formation. Initial total tocopherol contents of expressed oils ranged from 164 to 559 μg/g oil. Peanuts roasted at lower temperatures and darker colors had higher tocopherol contents. Glucose content was roast color and temperature dependent, while fructose was only temperature dependent. Soluble protein was lower at darker roast colors, and when averaged across temperatures, was highest when samples were roasted at 187 °C. Lysine content decreased with increasing roast color but was not dependent on temperature. MC strongly correlated with several components including tocopherols (R2 = 0.67), soluble protein (R2 = 0.80), and peak force upon compression (R2 = 0.64). The variation in characteristics related to roast conditions is sufficient to suggest influences on final product shelf life and consumer acceptability.Practical Application:  Peanuts are typically dry roasted to a specified surface color for a given food application; however, it is possible to obtain equivalent colors using different temperatures. This simple observation led to the overall goal of this research which was to determine if peanuts roasted to equivalent surface colors using different temperatures are equivalent from a quality perspective. Several compositional and textural measurements important to product quality differed based on the temperature used to achieve a given roast color. Overall, this study suggests there is good potential to optimize peanut quality by simply adjusting the time/temperature profiles during roasting.}, number={12}, journal={JOURNAL OF FOOD SCIENCE}, author={McDaniel, Kristin A. and White, Brittany L. and Dean, Lisa L. and Sanders, Timothy H. and Davis, Jack P.}, year={2012}, month={Dec}, pages={C1292–C1298} } @article{kane_davis_oakes_dean_sanders_2012, title={VALUE-ADDED PROCESSING OF PEANUT MEAL: ENZYMATIC HYDROLYSIS TO IMPROVE FUNCTIONAL AND NUTRITIONAL PROPERTIES OF WATER SOLUBLE EXTRACTS}, volume={36}, ISSN={["1745-4514"]}, DOI={10.1111/j.1745-4514.2011.00566.x}, abstractNote={Value-added applications are needed for peanut meal, which is the high-protein by-product of commercial peanut oil production. Peanut meal dispersions were hydrolyzed with alcalase, flavourzyme and pepsin in an effort to improve functional and nutritional properties of the resulting water soluble extracts. Degree of hydrolysis (DH) ranged from 20 to 60% for alcalase, 10 to 20% for pepsin and 10 to 70% for flavourzyme from 3 to 240 min. Low molecular weight peptides (<14 kDa) and unique banding patterns reflected the different proteolytic activities of each enzyme as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Total soluble solids and soluble nitrogen increased a minimum of 30 and 110%, respectively, for all hydrolysates after 4-h hydrolysis. Differences in air/water adsorption responses of hydrolysates were a function of protease specificity. Antioxidant capacities of all hydrolysates were greater than unhydrolyzed controls and correlated linearly (R2 = 0.87) with DH, whereas antioxidant capacities of hydrolysates were minimally dependent on bicinchoninic acid protein solubility or relative amino acid distribution. PRACTICAL APPLICATIONS Peanut meal is the high-protein by-product of commercial peanut oil production. While an excellent source of protein, aflatoxin contamination currently limits applications of peanut meal to feed markets. Recently described efforts to sequester aflatoxin from peanut meal during processing have proven successful, potentially allowing for processing of this material into value-added components including aflatoxin-free protein/peptide concentrates. Accordingly, the current manuscript focuses on the potential for enzymatic hydrolysis (three different proteases are compared) to improve functional and nutritional properties of peanut meal during processing. Enzymatic hydrolysis substantially increases solubility and antioxidant capacities of peanut meal hydrolysates. A potential mechanism for increased antioxidant capacity with increasing hydrolysis is discussed. These and other chemical/functional data within the manuscript directly apply to strategies for value-added processing of peanut meal.}, number={5}, journal={JOURNAL OF FOOD BIOCHEMISTRY}, author={Kane, Lauren E. and Davis, Jack P. and Oakes, Aaron J. and Dean, Lisa L. and Sanders, Timothy H.}, year={2012}, month={Oct}, pages={520–531} } @article{he_iasmin_dean_lappi_ducoste_reyes_2011, title={Evidence for Fat, Oil, and Grease (FOG) Deposit Formation Mechanisms in Sewer Lines}, volume={45}, ISSN={["1520-5851"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-79956022597&partnerID=MN8TOARS}, DOI={10.1021/es2001997}, abstractNote={The presence of hardened and insoluble fats, oil, and grease (FOG) deposits in sewer lines is a major cause of line blockages leading to sanitary sewer overflows (SSOs).

In this study, FOG deposits were formed under laboratory conditions from the reaction between free fatty acids and calcium chloride.

Results of FTIR analysis showed that the FOG deposits are metallic salts of fatty acid as revealed by comparisons with FOG deposits collected from sewer lines and pure calcium soaps.

Benzoyl peroxide (BP), a whey bleaching agent, degrades to benzoic acid (BA) and may elevate BA concentrations in dried whey products. No legal limit exists in the United States for BP use in whey, but international concerns exist. The objectives of this study were to determine the effect of hydrogen peroxide (HP) or BP bleaching on the flavor of 34% WPC (WPC34) and to evaluate residual BA in commercial and experimental WPC bleached with and without BP. Cheddar whey was manufactured in duplicate. Pasteurized fat-separated whey was subjected to hot bleaching with either HP at 500 mg/kg, BP at 50 or 100 mg/kg, or no bleach. Whey was ultrafiltered and spray dried into WPC34. Color [L*(lightness), a* (red-green), and b* (yellow-blue)] measurements and norbixin extractions were conducted to compare bleaching efficacy. Descriptive sensory and instrumental volatile analyses were used to evaluate bleaching effects on flavor. Benzoic acid was extracted from experimental and commercial WPC34 and 80% WPC (WPC80) and quantified by HPLC. The b* value and norbixin concentration of BP-bleached WPC34 were lower than HP-bleached and control WPC34. Hydrogen peroxide-bleached WPC34 displayed higher cardboard flavor and had higher volatile lipid oxidation products than BP-bleached or control WPC34. Benzoyl peroxide-bleached WPC34 had higher BA concentrations than unbleached and HP-bleached WPC34 and BA concentrations were also higher in BP-bleached WPC80 compared with unbleached and HP-bleached WPC80, with smaller differences than those observed in WPC34. Benzoic acid extraction from permeate showed that WPC80 permeate contained more BA than did WPC34 permeate. Benzoyl peroxide is more effective in color removal of whey and results in fewer flavor side effects compared with HP and residual BA is decreased by ultrafiltration and diafiltration.}, number={9}, journal={JOURNAL OF DAIRY SCIENCE}, author={Listiyani, M.

Our objective was to compare concentrations of inositol and metabolites associated with phytic acid and raffinosaccharide synthesis in developing seed of CX1834‐derived and normal lines. Plants were cultured with complete nutrient solutions in growth chambers with 650 to 700 μmol m−2 s−1 of photosynthetically active radiation and a 26/22°C day/night temperature. Seed inositol concentrations were high (60 to 90 mmol kg−1 seed dry wt.) at 20 d after flowering (DAF) and decreased 95% by maturity in both normal and low phytic acid lines. In two of three experiments, low phytic acid lines had significantly (p ≤ 0.05) greater seed inositol concentrations than normal lines at the first two sampling dates, but differences at maturity were not significant. Seeds of low phytic acid and normal lines had statistically similar concentrations (p > 0.05) of partially phosphorylated inositol intermediate (inositol triphosphate [IP3]), stachyose, raffinose, and phytase activity throughout development.
