Investigation Of Yield And Quality Of Grafted Heirloom And Hybrid Tomatoes, Stephen T. Flomo

Masters Theses & Specialist Projects

Tomatoes (Lycopersicon esculentum Mill) are one of the most popular vegetable crops grown for fresh market and processing in the U.S. Grafting involves the uniting of a shoot or bud scion with a rootstock to form a compound plant, mainly for managing soil-borne diseases and increasing crop yield. The objectives were to examine the effects of reciprocal and self grafts on tomato fruits, number of fruits, weight, and quality of the cultivars, ‘Cherokee Purple’, ‘Mister Stripey’, ‘Crista’, and ‘Maxifort’. Grafted seedlings were planted at WKU Farm on raised beds, protected with red or black plastic mulch under drip …

Effect Of Refrigerated Vacuum Storage On The Shelf Life Of Comingled Broccoli, Cauliflower, And Carrots, Ashley Spokowski

All Theses

The objective of this research was to study the interaction of comingled vegetables (broccoli, cauliflower, and carrots) in a refrigerated 30% vacuum system at various temperatures for 15 days. The vegetables were trimmed, washed, and randomly separated into 200 gram lots. They were placed into vacuum chambers and sealed. Each chamber was labeled with a temperature, sampling day, and treatment identification (vacuum vs non-vacuum). Samples were stored refrigerated set at 3, 7, and 11¡C. Samples were evaluated at (0, 5, 10, and 15 days). Analytical testing included; microbial population, texture, color, and gas headspace composition. There was no evidence that …

Changes In Microbiological, Physicochemical, Biochemical And Therapeutical Characteristics Of Yoghurt Upon The Addition Of Selected Medicinal Herbs., Afsaneh Najarian

Student Works (2010-2019)

The effects of herbs on the changes in probiotic growth and metabolism in yoghurt during storage were studied. Angelica sinensis, Codonopsis pilosula, Illicium verum, Lycium barbarum, Momorsdica grosvenori and Psidium gujava water-extracts were co-incubated with pasteurized full cream milk containing Lactobacillus acidophilus, Bifidobacterium, Streptococcus thermophilus and L.casei as starter culture. The addition of herbal water extracts stimulated Lactobacillus sp. growth in P. guajava–yoghurt (126.3±26.3 × 106 CFUml-1) only on day 0 and in L. barbarum–yoghurt from 0 to 3 days (109.3±21.5 to 112.7±28.8×106 CFUml-1 respectively) of refrigerated storage. The growth of S. thermophilus were recorded higher than plain yoghurt for …

Impact Of After-School Nutrition Workshops In A Public Library Setting, Marjorie Freedman, Audrey Nickell

Faculty Publications

Objective: To determine if after-school nutrition workshops conducted in public libraries were related to lasting changes in food choice.Methods: “Snack Smart” workshops, based on Social Cognitive Theory, were conducted in 8 branch libraries (49 ethnically diverse children, ages 9 to 14) to assess changes in consumption of targeted food items by pretest, posttest, and follow-up food frequency questionnaires. Results were analyzed using the Friedman test for repeated measures and Wilcoxon signed rank test.Results: Intake of milk, vegetables, and water significantly increased at 3-week posttest (P < .05), but only water intake showed a significant change from pretest to follow-up 3 months later.Conclusions and Implications: This low-intensity program did not produce lasting behavior change, as measured by changes in food frequency at 3 months post- intervention. The study supports the need to critically evaluate out-of-school nutrition programs for lasting impact.

Comparative Performance Of Fluorometry And High Performance Liquid Chromatography In The Detection Of Aflatoxin M1 In Two Commercial Cheeses, Gustavo Peña

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aflatoxin M1 (AFM₁) is frequently found in milk and dairy products. It is a metabolite formed in cows from aflatoxin B1 (AFB₁), contained in animal feeds. In cheese production AFM₁ distributes between curds and whey. In this study, cows were fed 64 µg/AFB₁/d for the high treatment, and 5 µg/AFB₁/d for the low treatment, to obtain milk contaminated with AFM1 over the 0.5 µg/L and under 0.05 µg/L restrictions, respectively. Cheese was manufactured with milk contaminated with AFM₁ at 0.8 and 0.03 ìg/kg by the higher and lower …

Financial Feasibility Of High Performance Low Rise Steel Buildings, Yolanda Maria Baez Batista

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Comparative performance evaluation including life cycle cost is currently being conducted on a series of conventional and base-isolated case study buildings. Alternative design approaches and their influence in cost were to be evaluated. This investigation is intended to contribute in the development of isolated structures by allowing engineers to communicate the cost of higher performance systems to their clients. The reported effort is part of a larger cost-benefit study for isolated steel buildings, and the purpose of this thesis is to compare initial investment of 3-story conventional and isolated steel buildings and determine how isolation affects the cost of the …

An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra

UNLV Theses, Dissertations, Professional Papers, and Capstones

Imported candies from Latin America pose a danger to children because of the potential for those candies to contain harmful levels of lead. This study sought to identify characteristics of imported candies that typically display higher concentrations of lead. This study also explored the Integrated Exposure Uptake Biokinetic model developed by the EPA. Using lead exposure data specific to Clark County, Nevada, the IEUBK model was used to estimate the amounts of candy a child would have to consume in order to raise his blood lead level to over 10µg/dL (the federal allowable limit).

The results showed that candies with …

Dynamic Predictive Model For The Growth Of Salmonella Spp. In Liquid Whole Egg And Risk Evaluation Of Egg White Hydrolysates Manufacturing Process For Spore Formers: Bacillus Cereus And Clostridium Perfringens, Aikansh Singh

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

A dynamic model for the growth of Salmonella spp. in liquid whole egg under continuously varying temperature was developed and validated. A primary model (Baranyi model) was fitted to each temperature growth data and corresponding maximum growth rates were estimated. Pseudo-R² values were greater than 0.97 for primary models. The maximum growth rates obtained from each primary model were then plotted against temperature and modeled using the modified Ratkowsky model. The pseudo-R² and root mean square error were 0.99 and 0.06 h^-1, respectively for the secondary model. A dynamic model for the prediction of Salmonella spp. …

DEVELOPMENT OF FOURIER TRANSFORM MID-INFRARED SPECTROSCOPY AS A METABOLOMIC TECHNIQUE FOR CHARACTERIZING THE PROTECTIVE PROPERTIES OF GRAIN SORGHUM AGAINST OXIDATION

Emily D. Sitorius, M.S. University of Nebraska, 2010 Advisor: Vicki L. Schlegel

Cellular oxidative damage has been linked to many chronic diseases including Alzheimer’s, diabetes, and cancer. Recent studies have shown that foods rich in antioxidants (i.e., grain sorghum) can protect against oxidative stress and thus reduce the risk of disease. However, a significant gap in knowledge exists in that dietary antioxidants are usually characterized by methods that determine free radical and reactive oxygen species’ scavenging capacity that are not …

Effects Of Feeding Distillers' Grains On Beef Quality, Amilton S. De Mello Jr.

Department of Animal Science: Dissertations, Theses, and Student Research

This research was conducted to understand the effects of feeding finishing diets containing distillers grains on beef quality. In the first and second studies, feeding wet distillers grains plus solubles (WDGS) increased proportions of PUFA, omega 6, omega 6/omega3, and trans fatty acids when compared to corn (P ≤ 0.05). Lipid oxidation was higher in muscles from animals fed WDGS when compared to corn (P ≤ 0.05). The third study examined the effects of feeding levels up to 50% of modified distillers grains plus solubles (MDGS) on fatty acid composition in beef. Linear increase (P ≤ 0.05) …
