An Investigation Of The Prevalence Of Disordered Eating Behaviors In Dietetic Students, Brandi Elizabeth Hicks

Theses, Dissertations and Capstones

Eating disorders are a debilitating mental illness that affects young people including those in the field of dietetics. Literature suggests that dietetic students have a higher prevalence of eating disorders than other students. Seventy-seven college student in Southern West Virginia enrolled in either dietetics or another major were included in a sample to determine if dietetic students have higher prevalence of disordered eating attitudes and behaviors. The participants completed a survey that included a general information section, a 26-item questionnaire concerning eating attitudes, and a behavioral information section. Upon completion of data collection, the survey was coded, and data was …

Fisheries Occasional Publication No. 31 - Feeding Lupins To Fish: A Review Of The Nutritional And Biological Value Of Lupins In Aquaculture Feeds, Brett Glencross

Fisheries Occasional Publications

Lupins are the harvested seed of species from the Lupinus genus, a group within the leguminous bean and pea family Fabaceae. Legumes are particularly valuable agricultural crops because of their capacity to provide a grain crop and also fix and return nitrogen to soils and improve the soil value for further cropping. The oilseeds, soybeans and peanuts are also leguminous plants, though traditionally they have been cropped for their oil value, whereas lupins, are cropped for both their protein and nitrogen fixing value (Gladstones, 1998; Perry et al., 1998).

The three key commercial species of lupins are L. angustifolius (Narrow-leafed …

Tyrosine And Phenylalanine Catabolism Bylactobacillus Cheese Flavor Adjuncts, S. Gummalla, Jeff Broadbent

Nutrition, Dietetics, and Food Sciences Faculty Publications

Bacterial metabolism of Tyr and Phe has been associated with the formation of aromatic compounds that impart barny-utensil and floral off-flavors in cheese. In an effort to identify possible mechanisms for the origin of these compounds in Cheddar cheese, we investigated Tyr and Phe catabolism by Lactobacillus casei and Lactobacillus helveticus cheese flavor adjuncts under simulated Cheddar cheese-ripening (pH 5.2, 4% NaCl, 15°C, no sugar) conditions. Enzyme assays of cell-free extracts indicated that L. casei strains catabolize Tyr and Phe by successive, constitutively expressed transamination and dehydrogenation reactions. Similar results were obtained with L. helveticus strains, except that the dehydrogenase …

Reversibility Of The Temperature-Dependent Opacity Of Nonfat Mozzarella Cheese, R. I. Dave, Donald J. Mcmahon, Jeff Broadbent, C. J. Oberg

Nutrition, Dietetics, and Food Sciences Faculty Publications

Salted and unsalted nonfat mozzarella cheese was made by direct acidification and stored at 4 degrees C over 60 d. Changes in cheese opacity were measured by using reflectance L* values while the cheese was heated from 10 to 90 degrees C, then cooled to 10 degrees C, and reheated to 90 degrees C. A characteristic opacity transition temperature (T(OP)) was obtained for each cheese. Both salt content and storage time influenced T(OP). Opacity during heating, cooling, and reheating formed a hysteresis. At d 1, the unsalted cheese became opaque when heated to 20 degrees C, but the salted cheese …

Hybridization Of Dna By Sequential Immobilization Of Oligonucleotides At The Air-Water Interface, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Anand Gole, K. N. Ganesh

Faculty Works

The hybridization of DNA by sequential electrostatic and hydrogen-bonding immobilization of single-stranded complementary oligonucleotides at the air-water interface with cationic Langmuir monolayers is demonstrated. The complexation of the single-stranded DNA molecules with octadecylamine (ODA) Langmuir monolayers was followed in time by monitoring the pressure-area isotherms. A large (and slow) expansion of the ODA monolayer was observed during each stage of complexation in the following sequence: primary single-stranded DNA followed by complementary single-stranded DNA followed by the intercalator, ethidium bromide. Langmuir-Blodgett (LB) films of the ODA-DNA complex were formed on different substrates and characterized using quartz-crystal microgravimetry (QCM), Fourier transform infrared …

Determination Of Wax Concentration In Sunflower-Seed Oil, Silvana Martini, M.C. Anon

Nutrition, Dietetics, and Food Sciences Faculty Publications

Isothermal crystallization of waxes was studied by using an optical setup. The induction time of crystallization was assessed as a function of wax concentration. The relationship was found to be a decreasing exponential curve. The wax content of some of the solutions prepared in the laboratory was determined by calculating the crystallization induction time. The values obtained were compared to those from different methods (cold test, microscopic, and turbidimetric methods). The results obtained with the optical setup method are similar to those obtained with other methods for concentrations greater than 100 ppm. An analysis of variance test was used to …

Practicality Of Large Mylar Bags To Store Corn And Beans In Kenya, Byu Food Quality Assurance Laboratory

Faculty Publications

The purpose of this study is to determine the practicality of using extra large zip-lock mylar bags with oxygen absorber packets to store corn and beans in Chyulu, Kenya. Weevil usually gets in the food after about 5 months, so if the oxygen can be maintained at a low level, the corn and beans could be stored for longer than that. The goal is to be able to store the food for 18 months. In order to determine the practicality of using the mylar bags to store corn and beans, the following questions will need to be answered: · Are …

Role Of Lipolysis And Lipogenesis In The Development Of Diet-Induced Obesity, Michael John Davies

Theses and Dissertations in Biomedical Sciences

Obesity is an increasingly common public health problem with approximately one-half of the American adult population overweight and one-quarter considered obese. This alarming trend has led researchers to determine potential causative factors of excess weight gain in humans. However, it is difficult to discern whether perturbations that result in obesity are the cause or simply the result of the obese state. Diet-induced obesity is one of the animal models that allow researchers to address temporal issues. Our laboratory utilizes a diet-induced obesity model in which Sprague-Dawley rats are placed on a purified moderately high fat diet and ultimately diverge into …

The Effect Of Exopolysaccharide-Producing Cultures On The Moisture Retention And Functional Properties Of Low Fat Mozzarella Cheese, David B. Perry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Low fat Mozzarella cheese was made using exopolysaccharide-producing starter cultures consisting of single strains of Streptococcus thermophilus MR-1C and Lactobacillus delbrueckii ssp. bulgaricus MR-1R with or without the addition of mesophilic exopolysaccharide-producing adjunct mixed culture consisting of Lactococcus lactis ssp. lactis and Lactococcus lactis ssp. cremoris. A control cheese was made using a non-exopolysaccharide-producing starter culture consisting of S. thermophilus TA061 and Lactobacillus helveticus LH100. Cheeses were analyzed for moisture, melt, fat, and protein. Cheeses made with the addition of the mesophilic exopolysaccharide-producing adjunct culture showed significant differences in moisture, but not in melting properties when compared to cheeses …

Affinity Purification Of Bovine Lactoferrin And Bovine Transferrin From Using Immobilized Gangliosides, Seung-Hee Nam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine lactoferrin (BLF) and bovine transferrin (BTF) are major-iron transport and regulation proteins found in bovine whey. BLF and BTF must interact with the eukaryotic cell surface to mediate their biological function of iron delivery and cellular functions of inflammatory and immunological modulation. As common components of the eukaryotic cell surface, gangliosides were used for affinity purification of BLF and BTF.

Bovine gangliosides were isolated from fresh buttermilk and covalently immobilized onto controlled-pore glass beads (66 μg/g beads). After the matrix was loaded with whey protein (WPI or WPC), lactoferrin was eluted with 1 M NaCl and identified by N-terminal …
