Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly

Graduate Theses and Dissertations

Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Calcium Intake Among Parents And Caregivers Of Children With A Milk Allergy Or Intolerance : A Comparative Analysis, Ilana Dubrovsky-Razam

Theses, Dissertations and Culminating Projects

Food allergies have become a global epidemic, affecting over 10% of the general population and 8% of children worldwide. Eliminating or limiting a food group from the diet can have adverse effects on micronutrient consumption. Milk allergies, for instance, can influence the amount of calcium consumed in the diet, particularly when limiting or excluding milk/milk-containing products from the diet. As milk products tend to be a primary source of dietary calcium, a milk allergy can serve as a barrier to meeting daily calcium needs.

Previous literature has analyzed the influence parents and caregivers have on their children’s diet, however, there …

Development Of An Equation To Correlate Brite Tank Temperature And Pressure To Beverage Carbonation Concentration, Devyn Meyer

Biological and Agricultural Engineering Undergraduate Honors Theses

The Carbo Rock-It™ is an invention created to carbonate beverages at craft breweries. One of the Carbo Rock-It’s main features is that it does not add a significant volume of undissolved gas bubbles to the brite tank in which the beverage is carbonated. This may allow temperature and pressure readings from the brite tank to be used to determine the concentration of dissolved carbon dioxide in the beverage continuously in real time. This eliminates the need for manual samplings, which could save breweries time and allow for more controlled, accurate carbonation. The goal of this project was to develop an …

Knowledge-Informed Data-Driven Modeling Of Microbial Inactivation In Food, Steve Zhang, Firnaaz Ahamed, Hyun-Seob Song

UNL Student Research Days Posters, Graduate

Prevention of the growth of harmful microorganisms in food products is an important requirement for ensuring food safety and quality. Mathematical models to predict the quantitative changes in microbial populations in food to the variations of environmental conditions are useful tools in this regard. Current approaches that use empirical formulation generate arbitrary forms of model equations, impeding systematic analysis towards identifying key factors governing microbial growth and inactivation in food. To address this challenge, we present a data-driven modeling pipeline that enables automatic discovery of model equations (through parsimonious selection of relevant terms in a pre-built library) without having to …
