Can Grain Be Disinfested In 5-Gal Hdpe Buckets Containing Oxygen Absorber Packets?, Lynn V. Ogden, C. Griffin

Faculty Publications

Effective methods of grain disinfestation include freezing, the use of carbon dioxide gas, and the use of pesticides. Oxygen deprivation has also been shown to be an effective method of disinfestation when the oxygen content is held below 1% for at least 12 days (d). High Density Polyethylene (HDPE) 5 gallon (gal) buckets have become a popular and convenient storage container for dry foods such as wheat, rice and beans. Oxygen absorber packets are an effective way to remove the oxygen in high-barrier sealed containers to prolong the life of many of these foods. It is hypothesized that sealed HDPE …

Total Protein Determination Using Micro Plate Assay, Julie Ruffatti Oct 2010

Total Protein Determination Using Micro Plate Assay, Julie Ruffatti

All Capstone Projects

One of the largest challenges that food manufactures are facing today is the management of food allergens. Allergenic protein in trace amounts, part per million concentrations, will trigger a reaction in some individuals. Food manufacturers need to prevent allergen cross-contamination by performing adequate sanitation after production of an allergenic containing food. Allergen detection kits are used to determine if sufficient protein was removed from the equipment surfaces during sanitation. One kit on the market is the 3M™ Clean- Trace™ Surface Protein (Allergen) swab tests. The test qualitatively detects the presence of protein based on the biuret reaction and will yield …

A “Healthy Pizza Kitchen” Nutrition Education Program At A Children's Health Museum, Marjorie Freedman Sep 2010

A “Healthy Pizza Kitchen” Nutrition Education Program At A Children's Health Museum, Marjorie Freedman

Faculty Publications

For nutrition education to be successful in changing behavior, schools, families, and communities must participate in or provide a variety of diverse, creative, accessible, and culturally appropriate programs. One venue for provision of nutrition education is a health and science education center that has exhibits and special programs not found in an average school. Establishing relationships with these organizations could greatly enhance a school health curriculum.1 Although nutrition information, displays, and programming are often found in these centers, studies examining whether provision of nutrition education in these venues increases knowledge or changes behavior are lacking. The purpose of this study, …

Beta Galactosidose Activity Of Commercial Lactase Samples In Raw And Pasteurized Milk At Refrigerated Temperatures, Trenton W. Horner Aug 2010

Beta Galactosidose Activity Of Commercial Lactase Samples In Raw And Pasteurized Milk At Refrigerated Temperatures, Trenton W. Horner

Theses and Dissertations

Many consumers are unable to enjoy the benefits of milk, due to lactose-intolerance. Lactose-free milk is available, but at about 2 times the cost of regular milk or greater, it may be difficult for consumers to afford. The high cost of lactose-free milk is in part due to the added cost of the lactose hydrolysis process. Hydrolysis at refrigerated temperatures, possibly in the bulk tank or package, could increase the flexibility of the process, and potentially reduce the cost. A rapid β-galactosidase assay was used to determine the relative activity of commercially available lactase samples at different temperatures. Four enzymes …

Barley For Brewing: Characteristic Changes During Malting, Brewing And Applications Of Its By-Products, Mahesh Gupta, Nissreen Abu-Ghannam, Eimear Gallaghar

Articles

Barley is the basic raw material for brewing. Its chemical composition, brewing, and technological indices are highly determinative for the beer quality and the economical efficiency of the brewing process. Barley is rich in protein, carbohydrates, dietary fibers, minerals, and vitamins. The presence of non starch polysaccharides as mixed linkage (1-3),(1-4)-β-D-glucans and arabinoxylans together with the enzymes are responsible for barley modification. Malting is a complex process that involves many enzymes; important ones are α-amylase, β-amylase, α-glucosidase, and limit dextrinase. During the process of malting and brewing, the by-products left after separation of the wort are rich in protein, fibers, …

Ribosomal Biosynthesis Of The Cyclic Peptide Toxins Of Amanita Mushrooms (Invited Review), Jonathan D. Walton, Heather E. Hallen-Adams, Hong Luo Aug 2010

Ribosomal Biosynthesis Of The Cyclic Peptide Toxins Of Amanita Mushrooms (Invited Review), Jonathan D. Walton, Heather E. Hallen-Adams, Hong Luo

Department of Food Science and Technology: Faculty Publications

Some species of mushrooms in the genus Amanita are extremely poisonous and frequently fatal to mammals including humans and dogs. Their extreme toxicity is due to amatoxins such as α- and β-amanitin. Amanita mushrooms also biosynthesize a chemically related group of toxins, the phallotoxins, such as phalloidin. The amatoxins and phallotoxins (collectively known as the Amanita toxins) are bicyclic octa- and heptapeptides, respectively. Both contain an unusual Trp-Cys cross-bridge known as tryptathionine. We have shown that, in Amanita bisporigera, the amatoxins and phallotoxins are synthesized as proproteins on ribosomes and not by nonribosomal peptide synthetases. The proproteins are 34–35 …

The Effects Of High Pressure Processing On Peanut Sauce Inoculated With Salmonella, Tara K. Stiles Aug 2010

The Effects Of High Pressure Processing On Peanut Sauce Inoculated With Salmonella, Tara K. Stiles

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Recent Salmonella outbreaks have prompted the need for new processing options for peanut products. Traditional heating kill-steps have shown to be ineffective in lipid-rich matrices such as peanut products. High pressure processing is one such option for peanut sauce because it has a high water activity, which has proved to be a large contributing factor in microbial lethality due to high pressure processing. Four different formulations of peanut sauce were inoculated with a five strain Salmonella cocktail and high pressure processed. Results indicate that increasing pressure or increasing hold time increases log10 reductions. The Weibull model was fitted to …

Change In Eating Competence In College Students Enrolled In Basic Nutrition Courses, Katrina J. Larsen Jul 2010

Change In Eating Competence In College Students Enrolled In Basic Nutrition Courses, Katrina J. Larsen

Theses and Dissertations

Objective: Determine change in eating competence (EC) and factors related to EC in students enrolled in basic nutrition courses at a major private university. Design: Eating competence was measured by administering the ecSatter Inventory (ecSI) both before and after class intervention. Additional data on eating disorder prevalence, food security, and general demographics were also collected in the same structured survey. Significance identified with p value <0.01. Setting/Participants: This survey was administered to 566 students enrolled in basic nutrition courses at a major private university in the western United States. Analysis: ANOVA was used to determine relationships between ecSI end scores and participant characteristics. ANCOVA was used to determine relationships between change in ecSI scores over time and participant characteristics. Results: Enrollment in NDFS 100 is associated with an overall increase in eating competence (EC). However, students with current eating disorders had a significant decrease in EC during enrollment. Current or past eating disorders and low or very low Food Security Status were associated with lack of EC. Females and younger participants were not eating competent at the course end. Enrollment in NDFS 201 was not associated with significant change in EC. Conclusions: Basic nutrition instruction improves EC among students without eating disorders. Low food security status and presence of an eating disorder may be a barrier to improving EC.

Effect Of Hydrothermal Processing On Colour, Antioxidant And Free Radical Scavenging Capacities Of Edible Irish Brown Seaweeds, Gaurav Rajauria, Amit Jaiswal, Nissreen Abu-Ghannam, Shilpi Gupta

Articles

The effect of heat processing on change in colour (ΔE), level of bioactive compounds and overall antioxidant capacity in raw and heat processed Irish brown seaweeds was investigated. Raw seaweeds were heated at 85, 95, 100, 110 and 121 °C for 15 min in an autoclave and the samples were extracted with 60% methanol. Total phenol (TPC), total tannin (TTC), DPPH• scavenging and metal chelating ability (FIC) were significantly higher (p < 0.05) at 85 °C while the value of ΔE, total flavonoid (TFC), total sugar (TSC), lipid peroxidation and H2O2 scavenging capacity were higher at 95 °C, as compared to raw seaweeds, in all the species studied. Results showed that heat treatment affects not only the content of bioactive compounds in seaweeds but also beneficial biological activity associated with these compounds which can suggest new processing for the application of seaweeds extract as nutraceutical.

Development And Use Of A Physiologically Based Mathematical Model Describing The Relationships And Contributions Of Macronutrients To Weight And Body Composition Changes, Saori Sakita Jul 2010

Development And Use Of A Physiologically Based Mathematical Model Describing The Relationships And Contributions Of Macronutrients To Weight And Body Composition Changes, Saori Sakita

Theses and Dissertations

The effect of the dietary macronutrient composition on weight loss has been a controversial issue for decades. During that time, a high-protein, high-fat, and low-carbohydrate diet has been one of the more popular weight loss diets with the public. We hypothesized that a computer simulation model using STELLA software could help to better understanding the effect of the dietary macronutrient composition on weight loss. We calculated daily total oxidation instead of total energy expenditure as others have done based on the facts that carbohydrate, fat, and protein intake influence carbohydrate, fat, and protein oxidation. In order to create a simple …
