Energy And Water Assessment And Plausibility Of Reuse Of Spent Caustic Solution In A Midwest Fluid Milk Processing Plant, Carly Rain Adams Nov 2018

Energy And Water Assessment And Plausibility Of Reuse Of Spent Caustic Solution In A Midwest Fluid Milk Processing Plant, Carly Rain Adams

Dissertations, Theses, & Student Research in Food Science and Technology

The Food Energy and Water Nexus (FEW Nexus) is the inseparable connection linking these resources. The concept of the FEW Nexus within the food industry addresses the connection of water and energy as key members of food production. The steady increase in population and the increase in food demand are directly related, therefore, the need for water and energy. Immediately taking on this critical challenge will lead to tangible impacts on the water and energy crisis facing the food system. To reduce the distance between process productivity and resource efficiency it must first be determined, within food processing, where water ...


Studies On The Physicochemical Characterization Of Flours And Protein Hydrolysates From Common Beans, Hollman Andres Motta Romero Nov 2018

Studies On The Physicochemical Characterization Of Flours And Protein Hydrolysates From Common Beans, Hollman Andres Motta Romero

Dissertations, Theses, & Student Research in Food Science and Technology

Pulses represent a rich source of nutrition and have several potential health benefits such as the reduction of the risk of developing cardiovascular diseases, obesity, and diabetes. Beans from the species Phaseolus vulgaris and Cicer arietinum are important crops raised in some regions of the United States, including Western Nebraska. Nevertheless, the traditional preparation procedures involved in the cooking of these beans are tedious and time-consuming, thus leading to the underutilization of these resources. Therefore, the present work focused on evaluating alternative utilizations of these beans in order to improve their economic value.

One alternative to improve the consumption of ...


A Risk-Based Approach To Evaluate The Impact Of Interventions At Reducing The Risk Of Foodborne Illness Associated With Wheat-Based Products, Luis Sabillon Oct 2018

A Risk-Based Approach To Evaluate The Impact Of Interventions At Reducing The Risk Of Foodborne Illness Associated With Wheat-Based Products, Luis Sabillon

Dissertations, Theses, & Student Research in Food Science and Technology

Pathogens are emerging on previously unrecognized food vehicles, such as wheat flour, which is a widely consumed commodity. Despite its low water activity, wheat-based ingredients and products have been implicated in several foodborne outbreaks over the last few years, resulting not only in the recall of food products but also in consumer illnesses. As a raw agricultural commodity, wheat is exposed to naturally occurring microbiological contamination that may compromise the overall safety of flour and other derived products. To address the increased concern regarding the safety of wheat-based foods, the objectives of the present research study were designed to develop ...


Ability Of Phenolics In Isolation, Components Present In Supina Turf Grass To Remediate Candida Albicans (A72 And Sc5314) Adhesion And Biofilm Formation, Fatima Alessa Aug 2018

Ability Of Phenolics In Isolation, Components Present In Supina Turf Grass To Remediate Candida Albicans (A72 And Sc5314) Adhesion And Biofilm Formation, Fatima Alessa

Dissertations, Theses, & Student Research in Food Science and Technology

Candida albicans inhabits the gastrointestinal tract dormant commensal member but can become an opportunistic pathogen when the host microflora or immune system is compromised. Adhesion to a biological or synthetic surface, followed by a morphological change from the yeast to hyphae phenotype. Biofilm formation is becoming a common occurrence on types of medical devices. Because C. albicans resistant to commonly available anti-fungal drugs is increasing, innovative treatments are critically needed. Phenolic compounds are promising anti-fungal synergists. Supina grass was used as the complex matrix as it is abundant and highly sustainable source of phytochemicals even though grass cuttings are typically ...


Implementation Of Iso/Iec Practices In Small And Academic Laboratories, Eric Layne Oliver Aug 2018

Implementation Of Iso/Iec Practices In Small And Academic Laboratories, Eric Layne Oliver

Dissertations, Theses, & Student Research in Food Science and Technology

Food Manufacturers are facing challenging times due to regulations such as the Food Safety Modernization Act (FSMA) requiring them to provide evidence they are producing safe foods. Food testing laboratories aid in the mitigation of food safety issues providing evidence that a manufacturers food safety system is acceptable. To perform these activities laboratories are required to adhere to certain standards such as ISO/IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories. However, implementation of ISO/IEC 17025 practices is challenging, especially for small and academic laboratories, due to lack of available guidance. A long-term goal of ...


Thermal Inactivation Kinetics Of Salmonella Enterica And Enterococcus Faecium In Ground Black Pepper, Sabrina Vasquez Aug 2018

Thermal Inactivation Kinetics Of Salmonella Enterica And Enterococcus Faecium In Ground Black Pepper, Sabrina Vasquez

Dissertations, Theses, & Student Research in Food Science and Technology

Food safety concerns of low-awfoods have boosted, given the increased number of foodborne illnesses related to these products. Black pepper, among other spices, has been implicated in several outbreaks and recalls in recent years.Salmonella entericahas been identified as the causing agent of outbreaks of contaminated spices. Therefore, increased efforts should be conducted to ensure food safety of spices, including black pepper. Food Safety Modernization Act (FSMA) demands all food processing facilities to conduct proper validations of the decontamination technologies applied to food products. Complete thermal process validations require a deep understanding of the thermal inactivation kinetics ...


Effect Of Processing On In-Vitro Protein Digestibility And Other Nutritional Aspects Of Nebraska Crops, Paridhi Gulati May 2018

Effect Of Processing On In-Vitro Protein Digestibility And Other Nutritional Aspects Of Nebraska Crops, Paridhi Gulati

Dissertations, Theses, & Student Research in Food Science and Technology

Among plant based agricultural products, Nebraska ranks first nationwide in the production of Great Northern beans (GNB), second in proso millet production, and eighth in production of winter wheat. The present research was focused on the effect of processing on nutritive components and in vitroprotein digestibility of these crops with the aim of promoting their human consumption. Proso millet based extrudates had physical properties similar to commonly extruded rice but had lower expansion than corn. GNB extrudates had limited expansion and high bulk density mostly due to high fiber and protein content. Extrusion significantly reduced the anti-nutritional components in ...


Effect Of Gallic And Ferulic Acids On Oxidative Phosphorylation On Candida Albicans (A72 And Sc5314) During The Yeast-To-Hyphae Transition, Rehab Aldahash May 2018

Effect Of Gallic And Ferulic Acids On Oxidative Phosphorylation On Candida Albicans (A72 And Sc5314) During The Yeast-To-Hyphae Transition, Rehab Aldahash

Dissertations, Theses, & Student Research in Food Science and Technology

Candida albicans is a dormant commensal in the mucosa of healthy individuals but can become an opportunistic pathogen when the host microflora is compromised. It has been reported as the most common cause of fungal infection among hospitalized U.S. patients, with elevated mortality rate. Candida species have been reported as resistant to antifungal drugs that increase the application of novel strategies to treat this infection. Among the natural compounds that have most gained attention as potential agents against fungi are phenolic compounds against fungi. C. albicans has the ability to switch phenotype from yeast-to-hyphae cells, with hyphae being the ...
