Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith Nov 2019

Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith

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

There is potential to increase microbiota accessible carbohydrates (MAC) in whole grains through food processing. Therefore, different processing conditions for boiling and extrusion of whole wheat flour were studied for their effect on MAC. Processing conditions had a minimal effect on fermentation response using 2 fecal samples of disparate composition. However, the processing method had an impact on the fermentation of non-digestible carbohydrates and subsequent short chain fatty acids production, but only for a microbiome with high diversity and a predominance of microbes associated with dietary fiber intake. Subsequently, five processing methods: boiling, extrusion, unleavened bread, yeast bread, and sourdough ...


A Comparative Analysis Of The Fermentation Capabilities Of Various Bifidobacterium Strains, Ella Oney Mar 2019

A Comparative Analysis Of The Fermentation Capabilities Of Various Bifidobacterium Strains, Ella Oney

Honors Theses, University of Nebraska-Lincoln

Bifidobacterium is a genus of anaerobic bacteria that are commonly found to inhabit the gastrointestinal tract of many members of the animal kingdom. These microorganisms are adapted to obtain their carbon from the breakdown of complex carbohydrates. Marmosets, a mammal whose gut microbiome is inhabited by high levels of Bifidobacteria, consume gum Arabic as a major part of their diet. The purpose of this experiment is to determine whether Bifidobacterium strains isolated from the guts of marmosets are able to degrade and ferment this complex carbohydrate or one of its main constituents, arabinose. This was accomplished by inoculating isolates of ...


The Use Of Grape By-Products As A Nutrient Rich Cattle Feed, Zachary Christman Mar 2018

The Use Of Grape By-Products As A Nutrient Rich Cattle Feed, Zachary Christman

Theses, Dissertations, and Student Research in Agronomy and Horticulture

In this article you will learn about how to use the grape stems, skins and pulp that are generated by the wine industry. Ruminant animals such as cattle can digest this inexpensive yet nutrient rich material. The complete process from wine press to cattle feed is covered in this article. The historical background of using grape by-products and methods to preserve this food source is also presented.


Food-Derived Bioactive Peptides In Human Health: Challenges And Opportunities, Subhadeep Chakrabarti, Snigdha Guha, Kaustav Majumder Jan 2018

Food-Derived Bioactive Peptides In Human Health: Challenges And Opportunities, Subhadeep Chakrabarti, Snigdha Guha, Kaustav Majumder

Faculty Publications in Food Science and Technology

Recent scientific evidence suggests that food proteins not only serve as nutrients, but can also modulate the body’s physiological functions. These physiological functions are primarily regulated by some peptides that are encrypted in the native protein sequences. These bioactive peptides can exert health beneficial properties and thus are considered as a lead compound for the development of nutraceuticals or functional foods. In the past fewdecades, awide range of food-derived bioactive peptide sequences have been identified, with multiple health beneficial activities. However, the commercial application of these bioactive peptides has been delayed because of the absence of appropriate and scalable ...


Growing Yeast For Livestock, Zachary Christman Jan 2017

Growing Yeast For Livestock, Zachary Christman

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Over 500,000 tons of organic materials such as food scraps are disposed of each year in Wisconsin. A large percentage of this material could be composted or turned into useful products.5 The purpose of this article is to educate farmers and organizations on how to turn food waste into a high value food source for livestock. Yeast can be grown at any time of the year without the large inputs of agricultural chemicals and machinery that is common with other feed production methods. A yeast growing facility can be scalable to any size the producer wants such as ...
