Gilts (49.3 kg of BW) were randomly assigned to a 3 x 2 factorial design, consisting of SF [0% SF, 4% yellow grease (YG), or 4% tallow] and linoleic acid (LA; 1% corn oil or 1% CLA). Animals were slaughtered (113 kg) after a feeding period of 47 d. A trained sensory panel (n = 6 members) developed a flavor profile on commercially cured bacon samples (12 descriptors) and center-cut, boneless, pork loin chops (18 descriptors, using a 14-point, universal intensity scale). Bacon samples from pigs fed 4% SF were considered to have a sweeter flavor (4.07 +/- 0.07) than those fed 0% SF (3.89 +/- 0.07; P < 0.04). The intensity of salty flavor was greater in bacon samples from pigs fed LA (6.18 +/- 0.09) compared with those fed CLA (5.86 +/- 0.10; P < 0.04). The intensity of salty aftertaste of bacon was greater when LA was combined with YG (5.21 +/- 0.14; P < 0.07) or tallow (5.44 +/- 0.14; P < 0.01) than for LA alone (4.85 +/- 0.14, but SF combined with CLA was not different from CLA alone (fat x LA; P < 0.02). Sour flavor intensity tended to be lower in loin samples from pigs fed CLA than for those fed LA (1.60 vs. 1.73 +/- 0.06; P < 0.09). Samples from animals fed 4% tallow tended to have lower (P < 0.09) notes of astringent aftertaste (1.42 +/- 0.08) compared with those fed 0% SF (1.62 +/- 0.09) or 4% YG (1.66 +/- 0.09). Overall, the flavor differences for bacon and loin samples were minimal, with most means differing by 1 point or less on the 14-point intensity scale. The sensory panel results indicate consumer acceptance of bacon and pork products from pigs fed CLA will not likely differ from commodity pork products.}, number={12}, journal={JOURNAL OF ANIMAL SCIENCE}, author={Gatlin, L.

In Exp. 1, 16 pigs (87.8+/-2.13 kg BW) were blocked by sex and weight and assigned randomly within block to one of three vitamin C treatments: 1) control; 2) 1,000 mg/L; or 3) 2,000 mg/L supplemented in the drinking water for a 48-h period. This was then followed by an additional 48-h period without supplemental vitamin C. Vitamin C increased plasma ascorbic acid concentrations (11.6, 19.5, and 23.4 microg/mL for 0, 1,000, and 2,000 mg/L of vitamin C; P < 0.05) within 6 h of supplementation. Plasma ascorbic acid concentrations from treated pigs decreased and did not differ from those of control pigs (13.7, 18.2, and 18.6 microg/mL for 0, 1,000, and 2,000 mg/L of vitamin C; P = 0.30) within 2 h of ending supplementation. No differences in plasma ascorbic acid concentrations were found between the two levels of supplementation. Vitamin C did not affect plasma oxalate or cortisol; however, cortisol tended to increase quadratically (P = 0.077) with vitamin C after 96 h. In Exp. 2, 30 pigs (107.5+/-0.54 kg BW) were blocked by sex and weight and assigned randomly within block to one of three vitamin C treatments: 1) control; 2) 500 mg/L; or 3) 1,000 mg/L supplemented in the drinking water 48 h before slaughter. Pigs were slaughtered 4 to 5 h after vitamin C supplementation ended, and loin samples were collected for meat quality measurements. At the time of slaughter, no differences in plasma ascorbic acid or cortisol were observed, but oxalate tended (P = 0.074) to increase quadratically with increasing vitamin C. Muscle ascorbic acid at slaughter and lactic acid in muscle at 0 and 1.5 h after slaughter were not different; however, lactic acid increased (P = 0.048) quadratically at 24 h after slaughter.

Vitamin C tended (P = 0.086) to increase oxidation in chops on d 0, but not d 4 or 8.

A series of 16 gels of varying structure (particulate or stranded) and lipid composition (0% to 20%) were developed at a constant protein concentration (12% w/v). Stranded gels had higher values for fracture strain, strain hardening, and held‐water. Particulate and stranded gels were similar in fracture stress. Eighteen sensory texture attributes were used to evaluate gels throughout the mastication process that was separated by the following phases: prefracture, 1st bite, chew‐down, and preswallowing. The 1st bite property of firmness and preswallowing properties of number of chews and time to swallow were the only sensory properties associated with lipid content. Fracture stress was correlated with these properties. The remaining 15 texture terms were primarily determined by gel structure type. It appears that gel structure type determines the primary texture properties of WPI emulsion gels. An increase in lipid content increases gel firmness and amount of chews required; however, it did not change the primary texture sensation.}, number={9}, journal={Journal of Food Science}, author={Gwartney, E.

A significant increase in volatile lipid oxidation products, most notably, hexanal, occurred during storage, and a corresponding decline in the free fatty acid linoleic acid was found. The flavor and aroma characteristic, cardboardy, was correlated to the increase in volatile lipid oxidation products and the decline in linoleic acid. Evidence strongly suggested that lipid oxidation was initiated during whey production and escalated during storage and that the starter cultures significantly influenced the level of volatile lipid oxidation products.

Functionality of whey products has been studied extensively. Flavor inconsistency and flavors which may carry through to the finished product can limit whey ingredient applications in dairy and nondairy foods. The goal of this research was to determine the flavor and flavor variability of commercially produced liquid Cheddar cheese whey. Liquid Cheddar cheese whey from five culture blends from two different stirred-curd Cheddar cheese manufacturing facilities was collected. Whey flavor was characterized using instrumental and sensory methods. Wide variation in whey headspace volatiles was observed between different manufacturing facilities (P < 0.05). Hexanal and diacetyl were two key volatiles that varied widely (P < 0.05). FFA profiles determined by solid-phase microextraction and degree of proteolysis of the whey samples were also different (P < 0.05). Differences in whey flavor profiles were also confirmed by descriptive sensory analysis (P < 0.05). Differences in liquid whey flavor were attributed to differences in milk source, processing and handling and starter culture blend. The flavor of liquid Cheddar cheese whey is variable and impacted by milk source and starter culture rotation. Results from this study will aid future studies that address the impact of liquid whey flavor variability on flavor of dried whey ingredients.}, number={2}, journal={JOURNAL OF DAIRY SCIENCE}, author={Whetstine, MEC and Parker, JD and Drake, MA and Larick, DK}, year={2003}, month={Feb}, pages={439–448} } @article{heugten_hasty_see_larick_2003, title={Storage stability of pork from Berkshire and Hampshire sired pigs following dietary supplementation with vitamin E}, volume={14}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-0037353707&partnerID=MN8TOARS}, DOI={10.1111/j.1745-4573.2003.tb00346.x}, abstractNote={ABSTRACT}, number={1}, journal={Journal of Muscle Foods}, author={Heugten, Eric and Hasty, J.

Milks with 2% (wt/wt) total fat (2% CLA, 1% CLA 1% milkfat, 2% milkfat) were made by the addition of cream or CLA triglyceride oil into skim milk followed by HTST pasteurization and homogenization. The effects of adding vitamin E (200 ppm) and rosemary extract (0.1% wt/wt based on fat content) were investigated to prevent lipid oxidation. HTST pasteurization resulted in a significant decrease of the cis-9/trans-11 isomer and other minor CLA isomers. The cis-9/trans-11 isomer concentration remained stable through 2 wk of refrigerated storage. A significant loss of both the cis-9/trans-11 and the cis-10/trans-12 isomers occurred after 3 wk of refrigerated storage. The loss was attributed to lipase activity from excessive microbial growth. No differences were found in hexanal or other common indicators of lipid oxidation between milks with or without added CLA (P > 0.05). Descriptive sensory analysis revealed that milks with 1 or 2% CLA exhibited low intensities of a "grassy/vegetable oil" flavor, not present in control milks. The antioxidant treatments were deemed to be ineffective, under the storage conditions of this study, and did not produce significant differences from the control samples (P > 0.05). CLA-Fortified milk had significantly lower L* and b* values compared with 2% milkfat milk. No significant differences existed in viscosity. Consumer acceptability scores (n = 100) were lower (P < 0.05) for CLA-fortified milks compared to control milks, but the addition of chocolate flavor increased acceptability (P < 0.05).}, number={1}, journal={Journal of Dairy Science}, author={Campbell, W. and Drake, M.

Pigs (49.3 kg) were randomly assigned to six diets (3 x 2 factorial) varying in supplemental fat (none, 4 g/100 g yellow grease or 4 g/100 g tallow) and linoleic acid [1 g/100 g corn oil (CO) or 1 g/100 g CLA (CLA-60)] for 47 d. Both the cis-9, trans-11 and the trans-10, cis-12 isomers of CLA were increased in belly and longissimus fat depots from pigs fed CLA, and that increase was up to 92% greater when CLA was fed with 4 g/100 g supplemental fat (fat source x linoleic acid interaction, P < 0.05). Pigs fed CLA had a greater concentration of 18:0 and less 18:1 cis-9 (P < 0.01) in various fat depots, suggesting a reduction in Delta(9) desaturase activity. The iodine value of belly fat from pigs consuming tallow and CLA combined was reduced to 62.0 from an initial value of 70.4. CLA supplementation also increased belly weights (P < 0.05).

Compared with the 6% tallow diet, LM from pigs fed the 4 or 6% safflower diets contained more pentanal, hexanal, 2-heptanone, trans-2-heptenal, 2-pentyl furan, 2-ethyl-1-hexanol, decanal, and undecanal.(ABSTRACT TRUNCATED AT 250 WORDS)}, number={5}, journal={JOURNAL OF ANIMAL SCIENCE}, author={LARICK, DK and TURNER, BE and SCHOENHERR, WD and COFFEY, MT and PILKINGTON, DH}, year={1992}, month={May}, pages={1397–1403} } @article{larick_turner_1990, title={FLAVOR CHARACTERISTICS OF FORAGE-FED AND GRAIN-FED BEEF AS INFLUENCED BY PHOSPHOLIPID AND FATTY-ACID COMPOSITIONAL DIFFERENCES}, volume={55}, ISSN={["0022-1147"]}, DOI={10.1111/j.1365-2621.1990.tb06751.x}, abstractNote={ABSTRACT}, number={2}, journal={JOURNAL OF FOOD SCIENCE}, author={LARICK, DK and TURNER, BE}, year={1990}, pages={312-&} } @article{larick_turner_1989, title={INFLUENCE OF FINISHING DIET ON THE PHOSPHOLIPID-COMPOSITION AND FATTY-ACID PROFILE OF INDIVIDUAL PHOSPHOLIPIDS IN LEAN MUSCLE OF BEEF-CATTLE}, volume={67}, ISSN={["0021-8812"]}, DOI={10.2527/jas1989.6792282x}, abstractNote={Angus and Angus/Hereford steers were allotted to either confined (all grain) or grain-on-grass feeding facilities. Cattle were slaughtered at an estimated Choice quality grade and pectoralis major muscles were obtained to evaluate the influence of diet and management system on fatty acid (FA) composition of lean. The FA composition of the neutral and polar lipids was evaluated. The polar lipids were separated into individual phospholipids and their FA profiles were examined. Muscle from the grain-on-grass cattle had greater quantities of polyunsaturated fatty acids (PUFA) in the neutral and polar lipids. Neutral lipids were higher in the fatty acids C18:2 and C18:3, whereas the polar lipids were higher in fatty acids C18:2, C18:3, C20:3, C20:4 and C22:5. Phosphatidylethanolamine, phosphatidylcholine + lysophosphatidylethanolamine and lysophosphatidylcholine were the most prevalent phospholipids. Each of these phospholipids had increased levels of C18:2, C18:3, C20:3, C20:4 and C22:5 in muscle from steers on the grain-on-grass treatment. This study confirms that diet can influence me PUFA composition of polar lipids in general and specifically of those phospholipids that previously have been associated with off-flavor and aftertaste in beef.}, number={9}, journal={JOURNAL OF ANIMAL SCIENCE}, author={LARICK, DK and TURNER, BE}, year={1989}, month={Sep}, pages={2282–2293} } @article{larick_turner_koch_crouse_1989, title={INFLUENCE OF PHOSPHOLIPID CONTENT AND FATTY-ACID COMPOSITION OF INDIVIDUAL PHOSPHOLIPIDS IN MUSCLE FROM BISON, HEREFORD AND BRAHMAN STEERS ON FLAVOR}, volume={54}, ISSN={["0022-1147"]}, DOI={10.1111/j.1365-2621.1989.tb04641.x}, abstractNote={ABSTRACT}, number={3}, journal={JOURNAL OF FOOD SCIENCE}, author={LARICK, DK and TURNER, BE and KOCH, RM and CROUSE, JD}, year={1989}, pages={521–526} }
