Use Of Origanum Vulgare Essential Oil To Combat Human Pathogenic Yeasts, Amber Adams
Mahurin Honors College Capstone Experience/Thesis Projects
With the outbreak of autoimmune diseases, pathogenic yeasts have begun to pose a serious medical threat. This threat is compounded as more of these yeasts evolve resistance to existing antifungal drugs. In the ever-widening search for new, effective antifungal treatment, the realm of herbal medicine offers some interesting and potentially valuable alternatives. Origanum vulgare is one herb that has demonstrated broad spectrum antimicrobial activity against bacteria and fungi alike. This study undertook to examine the effects of the essential oil of Origanum vulgare on Candida albicans, Cryptococcus neoformans, Rhodotorula rubrum, and Cryptococcus albidus, with the hypothesis that Essential Oil of …

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 …

Eat Smart. Play Hard™. San Luis Obispo!, a multi-component primary prevention program targeting low-income, Hispanic children 6-8 years, focuses on promoting healthy dietary and physical activity behaviors using an innovative child-adult buddy system approach. The child-adult buddies participate in multiple activities to increase their consumption of fruits and vegetables, and level of physical activity and decrease their consumption of sweetened beverages. The results of the pilot program show high program satisfaction and improvements in dietary and physical activity behaviors. Such programs provide an opportunity to establish and promote healthy behaviors among young children and ultimately prevent overweight development.

We investigated whether lipid extract from a blue-green alga, N. commune, modulates proinflammatory gene expression in RAW 264.7 macrophages. The cells were incubated with N. commune lipid extract (0–100 μg/mL) and subsequently activated by LPS (100 ng/mL). 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 …

Modeling Residence Time Distribution In A Twin-Screw Extruder As A Series Of Ideal Steady-State Flow Reactors, Ajay Kumar, Girish M. Ganjyal, David D. Jones, Milford Hanna
Department of Food Science and Technology: Faculty Publications
Knowledge about and control of residence time distribution (RTD) is critical for determining optimal conditions in an extrusion process. In this paper, previously proposed models for RTD have been summarized and compared with the experimental data. The best-fit model was found to be a plug flow in series with a finite number of constantly stirred tank reactors having dead volume fractions. Parameters of the best-fit model were predicted from input variables (moisture content, screw speed, nozzle diameter and barrel temperature). Predicted RTD from the input variables had a r 2> 0.96. Experiments were conducted using a full factorial design with …

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 …

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.

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 …

Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
To maximize rice quality, it is essential to quantify the various factors that affect milling properties of rice. Rice aging, a process during which rice undergoes a series of chemical and physicochemical changes, affects head rice yield (HRY) and the rate at which HRY changes with degree of milling (DOM). This study examined effects of storage duration (0, 2, and 4 months) and storage temperature (4, 21, and 35°C) on milling properties of ‘Wells’ (long-grain) and ‘Jupiter’ (medium-grain) rice cultivars. In general, HRY increased with storage duration, most significantly for Wells cultivar. Millability curves were developed by plotting HRY vs. …

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 …
