Impact Of Ultrasonication On Physicochemical Properties And Digestibility Of Sorghum Starch, Zhihong Wang

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Sorghum, a highly nutritious grain, is usually not considered as a main staple in many families because it is not as easy to be digested as other grains such as rice or maize. But recent studies of ultrasonication shed a light on potential utilization of this world’s fifth important cereal other than being raw material source of biofuel or liquor. This experiment was meant to compare the differences between unsonicated and sonicated sorghum starch in terms of their physical chemical properties and digestion ability. Despite their similarities in shapes under microscopes and their thermal properties, but sonicated sorghum starch ...

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 ...


Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane 2018 University of Arkansas, Fayetteville

Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

Obesity prevalence in the United States continues to increase and is associated with health consequences such as type 2 diabetes, hypertension, atherosclerosis, and hyperlipidemia. Among many contributing factors to obesity, fructose may be one of the major reasons as it disrupts the antioxidant system thereby resulting in an accumulation of reactive oxidative species and leading to obese conditions. The enzyme, isocitrate dehydrogenase 2 (IDH2), reduces nicotinamide adenine dinucleotide phosphate from the TCA Cycle, hence might be implicated with not only energy metabolism but also cellular redox homeostasis. Therefore, the hypothesis was that IDH2 deficiency in mice would exacerbate hepatic lipid ...

How To Be The Perfect Asian Wife!, sophia hill 2018 Macalester College

How To Be The Perfect Asian Wife!, Sophia Hill

Art and Art History Honors Projects

“How to be the Perfect Asian Wife” critiques exploitative power systems that assault female bodies of color in intersectional ways. This work explores strategies of healing and resistance through inserting one’s own narrative of flourishing rather than surviving, while reflecting violent realities. Three large drawings mimic pervasive advertisement language and presentation reflecting the oppressive strategies used to contain women of color. Created with charcoal, watercolor, and ink, these 'advertisements' contrast with an interactive rice bag filled with comics of my everyday experiences. These documentations compel viewers to reflect on their own participation in systems of power.

Knowledge Gained From Good Agricultural Practices Courses For Iowa Growers, Angela M. Shaw, Catherine H. Strohbehn, Linda L. Naeve, Paul A. Domoto, Lester A. Wilson

Angela M. Shaw

Good Agricultural Practices (GAP) educational courses provide produce growers with the fundamental information for producing and processing safe produce. To determine the effectiveness of the current 7- hour GAP course provided in Iowa, growers were surveyed before and 7-14 days after the course to determine changes in knowledge and opinions. Results show that growers positively changed their knowledge and opinions on key food safety principles and regulations, which provides evidence that Extension programming is an effective method to educate small growers. Food safety educators should focus their training on practical methods for documentation, sanitation, and facilities.

Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins 2017 University of Arkansas, Fayetteville

Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins

Theses and Dissertations

Upon entering a poultry processing facility, birds are already contaminated with a variety of microorganisms. It is the responsibility of the processor to reduce these numbers to deliver a wholesome product to customers. This is not an easy task as there are ample opportunities for further microbial contamination. Some of these opportunities are obvious. For example, any areas where contaminants could be washed off one bird and onto another are always an area for concern, i.e. the scalder or the chiller. There are numerous opportunities for contamination that are not so obvious. These incidents of contamination are not necessarily ...

Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma

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

Whole grains are a major source of dietary fibers in the human diet that provide specific nutrients to the gut microbiota and thereby plays a major role in modulating microbiota composition and increasing diversity of the gut ecosystem. A common approach of consuming whole grains is in the form of ready-to-eat extruded breakfast cereals. Studies reported herein established that extrusion conditions not only affected the physicochemical properties but also in vitro starch digestibility, β-glucan extractability and in vitro fermentation characteristics of whole grain oats. Moderate screw speed (300 rpm) led to higher slowly digestible starch (SDS) with an accompanying decrease ...
