Protein Enriched Bread Using Spent Wine Yeast, Zachary Christman

Applied Science Program: Theses

Yeast is a common byproduct of wine production. Wine yeast may be used as a food source. It does not contain bitter and astringent compounds such as those present in spent yeast from making beer The use of nutritional yeast and yeast extract for protein enrichment of bread are presented in this article.

Optimizing Soil Nutrient Management To Improve Dry Edible Bean Yield And Protein Quality, Emily Jundt

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

Soil nutrient management is of the utmost importance to ensure crop yields are maximized to feed the world’s growing population. Micro and macronutrient deficiencies can be detrimental to plant growth and cause a drastic reduction in yield. Optimization of nutrient management needs extensive research. Nutrients such as nitrogen increase crop yield, even in legumes capable of using a large amount of nitrogen (N) via biological N fixation. Iron (Fe) fertilizers are also crucial for legumes as they are susceptible to Fe deficiency induced chlorosis.

Dry edible beans (Phaseolus vulgaris) are leguminous plants and excellent dietary protein sources. Great …

Krill Protein Fortified Extrudates: A Pilot Study, Avery S. Fleeharty

Graduate Theses, Dissertations, and Problem Reports

Antarctic krill (Euphausiacea superba) is an abundant and sustainable but underutilized natural resource with well-studied protein isolation methodology using Isoelectric solubilization-precipitation (ISP). The resulting krill protein isolate (KPI) has high yield and sufficient impurity removal in addition to desirable nutritional and functional properties but has yet to be used in food systems. Extrusion is a versatile and scalable food processing method with many benefits; thus, the aim of this study was to determine the impact of KPI as an additive in extrusion processing with the eventual goal of introducing it to human and animal food systems. KPI was …

Evaluating The Efficacy Of Germination And Fermentation In Producing Biologically Active Peptides From Pulses, Ashley Newton

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

Recently, there has been a profound increase in demand of plant-based proteins, especially pulse proteins. However, pulses contain high concentrations of antinutritional factors that hinder the digestibility of proteins. Processing techniques such as enzymatic hydrolysis, microbial fermentation, and physical processing modulate nutritional quality and functionality of pulses. Processing also releases peptides from parent proteins that exhibit health-beneficial bioactivity against various disease risk factors. In this study, germination, gastrointestinal digestion, and microbial fermentation were evaluated to determine the nutritional quality and release of bioactive peptides during and after processing.
