Influence Of Dietary Polyphenols On Carbohydrate Intestinal Digestion And Absorption, Sydney E. Moser

Open Access Dissertations

Both epidemiological and clinical evidence support the notion that polyphenol rich foods and beverages may modify glycemic response, glucose homeostasis and subsequent risk of Type-2 diabetes. In vitro evidence typically derived from experiments with pure phenolics and phenolic rich extracts have pointed to this benefit being associated with two potential mechanisms: (1) the ability of specific polyphenolics to inhibit carbohydrate digestion (amylase and glucosidase) and (2) polyphenolic inhibition of intestinal glucose transport. While the high potential of these activities is evident, little is actually known regarding the extent to which these benefits are extendable to the actual food matrix these …

Rice Consumption And Effects Of Rice Cake, Seolgitteok, On Human Health, Ellen Joy Pottgen

Graduate Theses and Dissertations

The prevalence of colorectal cancer (CRC) has been increasing in recent years worldwide. In the United States, it is ranked the second leading cause of cancer death. Risks of CRC increase with age and are associated with several lifestyle factors such as diet, drinking and smoking habits, and levels of physical activity. There is an abundance of scientific literature demonstrating the protective roles of several dietary components including fibers and polyphenolic compounds. These compounds have been shown to be able to positively modulate gastrointestinal ecology by increasing the production of short-chain fatty acids (SCFA) and promoting the population of beneficial …

Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Black beans contain high phenolic contents that are considered potent antioxidants. Relatively little is known about their ability to inhibit the carbohydrate-hydrolyzing enzymes α-amylase and α-glucosidase from releasing glucose from starch and/or disaccharides. The objective of this project was to determine the optimum procedures for extracting total phenols (TP), total flavonoids (TF) and total condensed tannins (TCT) from black beans (Phaseolus vulgaris), and then to determine the ability of the phenolic rich extracts to inhibit α-amylase and α-glucosidase. Due to their high phenolic levels, it was hypothesized that black beans would be an effective inhibitor of α-amylase and α-glucosidase, which …

The Effect Of Protein Quantity And Quality At Breakfast On Energy Metabolism, Appetite And Metabolic Health, Brianna Lynne Neumann

Graduate Theses and Dissertations

Obesity is a global health concern and, within the United States, the current obesity rate is 36% and projected to double within the next two decades. Obesity is linked to many chronic diseases such as cancer, heart disease and type 2 diabetes. In young females, weight gain (5-11 kg) between the ages of 20-30 years increases the risk of developing type 2 diabetes and cardiovascular disorders later in life. The cause of obesity is multifactorial in nature, however fundamentally weight gain occurs when energy intake is greater than energy expended (i.e. calories in > calories out). Therefore, identifying and validating nutritional …

Crystallization Behavior Of Waxes, Sarbojeet Jana

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Partially hydrogenated oil (PHO) has no longer GRAS status. However, PHO is one of the important ingredients in bakery and confectionary industry and therefore the food industry is seeking for an alternative fat to replace PHO. Waxes have shown promise to fulfill that demand because of its easy availability and cheap in price. Waxes with high melting points (> 40 °C) help in the crystallization process when mixed with low melting point oils. A crystalline network is formed in this wax/oil crystallization process where liquid oil is entrapped in wax crystal network. A new material is formed which is neither …

The Effect Of Monetary Reward And Food Type On Motivation Of Untrained Sensory Panelists In Triangle Tests, Jessilee Noel Loucks

Theses and Dissertations

Although human panelists provide unparalleled data, they are prone to bias, which is a primary concern of sensory scientists. Motivational bias is of concern because it determines how much effort a panelist will exert to be consistent, find a difference, or use appropriate descriptors when taking a test. For central location tests, money has become a common motivational device to compensate panelists for their time and effort. Studies have documented that money can change results in sensory testing but have not measured the impact on motivation. Additionally, little research has been conducted on the effect of the test food itself …
