Enhanced Lipid Stability In Whole Wheat Flour By Lipase Inactivation And Antioxidant Retention, Devin J. Rose, Lynn V. Ogden, Michael L. Dunn, Oscar A. Pike

Faculty Publications

The purpose of this study was to determine the effectiveness of dry heat, steam, and microwave treatments in decreasing lipase activity, while retaining antioxidant activity, to stabilize whole wheat flour against lipid degradation during storage. Bran was heat-treated in 230-g batches using four levels (exposure times) for each of the three treatment methods. Lipase activity and antioxidant activity were quantified for all treatment combinations. None of the treatments significantly decreased antioxidant activity; the levels determined to be optimal, inasmuch as further heating did not significantly decrease lipase activity, were 25 min of dry heat, 60 sec of microwave (1000W), and …

Quantitative real-time PCR analysis showed that mRNA abundance of proinflammatory mediators, including TNF-α, COX-2, IL-1β, IL-6, and iNOS, was significantly reduced by N. commune lipid extract in a dose-dependent manner. Secretion of TNF-α and IL-1β into cell culture medium was also significantly decreased by N. commune lipid extract. Thin-layer chromatography-densitometry analysis showed that N. commune …

Loco Labels And Marketing Madness: Improving How Consumers Interpret Information In The American Food Economy, Margaret Sova Mccabe

Law Faculty Scholarship

America's current food labeling scheme, as illustrated by the example of salt, is flawed when examined from the consumer and public health perspective. While the Food, Drug, and Cosmetic Act has sound scientific standards, those standards as currently applied to labels do not efficiently signal health information to consumers. Without better information on labels, consumers will continue to make poor choices at the grocery store. However, there are promising new ways to label. Both the United Kingdom and the domestic supermarket chain Hannaford’s have implemented simple health labeling on food packaging or grocery shelves to improve the amount and location …

An Hsus Report: Food Safety Concerns With The Slaughter Of Downed Cattle, The Humane Society Of The United States

Impact of Animal Agriculture

Nonambulatory cattle may be at higher risk of harboring foodborne pathogens such as E. coli O157:H7, Salmonella, and, very rarely, the infectious agent that causes bovine spongiform encephalopathy, colloquially known as “mad cow disease.” The exclusion of nonambulatory cattle from slaughter for human consumption may strengthen the safety of the food supply and is a prudent measure already in place throughout the European Union.

Voluntary Exercise Inhibits Intestinal Tumorigenesis In Apc(Min/+) Mice And Azoxymethane/Dextran Sulfate Sodium-Treated Mice., Jihyeung Ju, Bonnie Nolan, Michelle Cheh, Mousumi Bose, Yong Lin, George C. Wagner, Chung S. Yang

Department of Nutrition and Food Studies Scholarship and Creative Works

BACKGROUND: Epidemiological studies suggest that physical activity reduces the risk of colon cancer in humans. Results from animal studies, however, are inconclusive. The present study investigated the effects of voluntary exercise on intestinal tumor formation in two different animal models, Apc(Min/+) mice and azoxymethane (AOM)/dextran sulfate sodium (DSS)-treated mice. METHODS: In Experiments 1 and 2, five-week old female Apc(Min/+) mice were either housed in regular cages or cages equipped with a running wheel for 6 weeks (for mice maintained on the AIN93G diet; Experiment 1) or 9 weeks (for mice on a high-fat diet; Experiment 2). In Experiment 3, male …

Engine Performance Test Of Cottonseed Oil Biodiesel, Xiaohu Fan, Xi Wang, Feng Chen, Daniel P. Geller, Peter J. Wan

Publications

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8%, CO2 by 11.1% and NOx by 10%, though there was no significantly statistical difference at p<0.05. The engine test also showed a slightly higher amount of consumption and less tendency of coke formation from COME than the No. 2 diesel fuel. The oxidative stability study showed COME with acceptable stability. COME exhibited friendly environmental benefits and acceptable stability, demonstrating its feasibility as an alternative fuel.

Effect Of Food Deprivation On The Metabolic Profile Of Llamas (Lama Glama) In The Letanias Experimental Station - Viacha, Edwin Eddy Ali Quisbert

Theses and Dissertations

In the highlands, where regular agriculture and livestock are not viable, raising camelids is the only means of subsistence for rural families. While grazing during the dry season in the high Andean region, llamas face serious nutritional deficiencies due to limited forage availability. This study was done at the experimental station of the Benson Agriculture and Food Institute located in the community of Letanias which is in the municipality of Viacha. The objective was to determine the effect of food deprivation on the metabolic profile of blood plasma (concentration of urea-nitrogen, total protein, albumin, and creatinine) as well as the …

Effect Of Micronutrient Fortification On Nutritional And Other Properties Of Nixtamal Tortillas, K. E. Burton, Frost M. Steele, Laura K. Jefferies, Oscar A. Pike, Michael L. Dunn

Faculty Publications

Nixtamalization is the process of steeping dried corn in hot water with calcium hydroxide (lime) with subsequent removal of all or most of the pericarp through washing. The resulting product is called nixtamal. Approximately 60% of corn tortillas in Mexico are produced from nixtamal, with the remainder prepared from nixtamalized corn flour. Nixtamal was fortified with micronutrient premix containing iron, zinc, folic acid, niacin, riboflavin, and thiamin. Premix composition followed a proposed Mexican regulation for corn flour fortification, adjusted for moisture. Effects of premix on masa adhesiveness, hardness, and pH, as well as tortilla sensory properties, stretchability, rollability, and color …

Subcritical Water And Carbonated Water Extraction Of Anthocyanins From Grape Pomace, Lydia Rice, L. R. Howard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Grape pomace, a by-product of juice and wine processing, is a rich source of anthocyanins, antioxidant compounds that may afford protection against cancer and coronary heart disease. Unfortunately, traditional extraction of these antioxidants involves use of organic solvents, which pose serious safety and disposal problems for industry. Clearly a need exists for “green” extraction technologies—such as use of subcritical water—that eliminate or reduce the amount of organic solvents. In this study, we determined the efficacy of subcritical and carbonated water in extraction of anthocyanins from red grape pomace. Extraction variables including particle size, pomace mass, and temperature were optimized, and …

Quantitative Trait Locus Mapping For Seed Mineral Concentrations In Two Arabidopsis Thaliana Recombinant Inbred Populations, Brian M. Waters, Michael A. Grusak

Department of Agronomy and Horticulture: Faculty Publications

Biofortification of foods, achieved by increasing the concentrations of minerals such as iron (Fe) and zinc (Zn), is a goal of plant scientists. Understanding genes that influence seed mineral concentration in a model plant such as Arabidopsis could help in the development of nutritionally enhanced crop cultivars. Quantitative trait locus (QTL) mapping for seed concentrations of calcium (Ca), copper (Cu), Fe, potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P), sulfur (S), and Zn was performed using two recombinant inbred line (RIL) populations, Columbia (Col) × Landsberg erecta (Ler) and Cape Verde Islands (Cvi) × Ler, grown …

The Effect Of The Food Allergen Labeling And Consumer Protection Act (Falcpa) On The Accidental Food Allergen Ingestion Rate In Adults With Self-Reported Food Allergies, Susan Liebert

Master's Theses and Doctoral Dissertations

Background: The Food Allergen Labeling and Consumer Protection Act (FALCPA) recently required bolded allergens or “contains” statements on food product labels. Very few U.S. studies have looked at the accidental food allergen ingestion rate in adults. Since the emotional and medical costs of allergic reactions can be high, it is important to determine if the FALCPA is helping to reduce the accidental food allergen ingestion rate in adults with self-reported food allergies.

Optimisation Of Steamer Jet-Injection To Extend The Shelf Life Of Fresh-Cut Lettuce, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Gary Henehan, J. Barat, Jesus Maria Frias

Articles

Optimisation of short time blanching (steaming) was investigated using response surface methodology by analysing quality and microbial and nutritional markers over the shelflife of packaged fresh-cut lettuce. Steamer treatment time (5–10 s) and storage (1–10 days) were used as independent factors in order to optimise the process. Longer treatments (>10 s) were not feasible because of extensive damage caused to lettuce tissue. Significantly (p < 0.05) higher values of luminosity (L*), greenness (−a*) and sensory panel scores (fresh appearance, general acceptability and absence of browning) were obtained with samples treated for longer times with the steamer. Activity of browning-related enzymes present in photosynthetic tissue decreased in all the cases, however, longer treatment time (7.5–10 s) was needed with vascular tissues to reduce to similar activity values. These differences could be explained by the variation in tissue thickness. The longest steam treatment (10 s) reduced and maintained significantly (p < 0.05) lower mesophilic load than shorter treatments (5–8.5 s). However, significant (p < 0.05) decreases in vitamin C and carotenoids were observed in samples treated with longer treatments. Steamer treatment of 10 s could be considered the optimum time for maintaining the shelflife (mainly texture and browning) of fresh-cut lettuce for 7–10 days in optimum conditions.

Use Of Neutral Electrolysed Water (Ew) For Quality Maintenance And Shelf-Life Extension Of Minimally Processed Lettuce, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Jesus Maria Frias, Gary Henehan, José Barat

Articles

Experiments were conducted to determine the effectiveness of different treatments based on the use of neutral electrolysed water (EW) on fresh-cut lettuce. EW was diluted to obtain different free chlorine concentrations (120, 60 and 12 ppm) and compared with standard washing treatment of 120 ppm chlorine solution. Shelf-life quality and safety markers were studied at the beginning and at the end of the 7-day storage at 4 ºC. The use of EW decreased the respiration rate of the samples which might be related with the observed reduction in microbial spoilage. The use of EW also increased the activity of a …

Regional Body Composition In College-Aged Caucasians From Anthropometric Measures, Robert T. Davidson, Cameron B. Ritchie

Faculty Publications

Quantitating fat and lean tissue in isolated body regions may be helpful or required in obesity and health-outcomes research. However, current methods of regional body composition measurement require specialized, expensive equipment such as that used in computed tomography or dual energy x-ray absorptiometry (DEXA). Simple body size or circumference measurement relationships to body composition have been developed but are limited to whole-body applications. We investigated relationships between body size measurements and regional body composition. Methods Using DEXA technology we determined the fat and lean tissue composition for six regions of the body in predominantly Caucasian, college-aged men (n = 32) …
