Potato Cultivar Differences Associated With Mealiness, Diane R. McComber, Harry T. Horner, Mark A. Chamberlin, David F. Cox 2016 Iowa State University

Potato Cultivar Differences Associated With Mealiness, Diane R. Mccomber, Harry T. Horner, Mark A. Chamberlin, David F. Cox

Harry Horner

Russet Burbank, Norchip, Pontiac, and LaSoda potato cultivars were examined for the parameters mealy and waxy. Russet Burbank was judged dry, hard and particulate, typifying mealiness. Using phase contrast microscopy and scanning electron microscopy, raw mealy cells were determined to be larger and more irregularly shaped than cells from waxy cultivars. Mealy cooked cells were engorged with gelatinized starch, cell walls were more polarized, and cell shapes were better retained after mashing, when compared to waxy cells. NMR-T2 bound water readings from Russet Burbank and Pontiac samples did not differ from each other. Starch granule sizes and shapes varied by ...

Nutrition & Health Sciences Dissertations & Theses

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 ...

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

Abstract

Over 30% of adults in the US are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n=4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in randomized, crossover design with a one-week washout period. Each test day EE, appetite, and cravings were assessed at ...

The Archaeology Of Appetites, Molly S. Schonert

SEWSA 2016 Intersectionality in the New Millennium: An Assessment of Culture, Power, and Society

Through use of examining how food is produced, stored, distributed and consumed, one can take a glimpse into the past, present and even future of this planet–to better understand the complexity of human identity and the social practices or roles that define an individual, community or society. So this begins an exploration of the archaeology of food as a gendered commodity throughout our evolutionary past, emphasizing the infinite ways in which foodway practices exceeds the nutritional value of what our ancestors, family, friends and ourselves consume(d) on a daily basis. Foodways practices is an invaluable tool in any ...

GW Research Days 2016 - Present

Epidemiologic studies report associations between artificial sweetener (ASW) consumption and metabolic abnormalities, yet well-designed human intervention studies in humans are limited. Given that ASW contain no or few calories, one potential mechanism through which ASW may influence metabolic risk is through altering the gut microbiota. As alterations in the gut microbiota are known to be implicated in the development of metabolic disease, the purpose of this study was to investigate the effects of one week of three times daily diet soda (with ASW) consumption on the gut microbiota in healthy college students. We hypothesized that participants randomized to consume diet ...

Evaluation Of Vacuum Packaging On The Physical Properties, Solubility, And Storage Space Of Dairy Powders, Hadi Eshpari 2015 California Polytechnic State University – San Luis Obispo

Evaluation Of Vacuum Packaging On The Physical Properties, Solubility, And Storage Space Of Dairy Powders, Hadi Eshpari

Hadi Eshpari

As many of the dairy powders manufactured have to travel long distances to reach their customers, both domestically and internationally, there is considerable interest among dairy powder manufacturers to maintain the quality of their products for relatively long storage periods. Dairy powders can have a long shelf life if packaged and stored properly. Vacuum packaging can be an attractive packaging strategy to maintain the quality of dairy powders and provide added value by improving the efficiency of using the storage space; because of the inherent compactness of these products. Vacuum packaged dry dairy ingredients may also have added ease of ...

Faculty Publications in Food Science and Technology

A prototype on-line acousto-optic tunable filter (AOTF)-based hyperspectral image acquisition system (λ = 450– 900 nm) was developed for tenderness assessment of beef carcasses. Hyperspectral images of ribeye muscle on stationary hanging beef carcasses (n = 338) at 2-day postmortem were acquired in commercial beef slaughter or packing plants. After image acquisition, a strip steak was cut from each carcass, vacuum packaged, aged for 14 days, cooked, and slice shear force tenderness scores were collected by an independent lab. Beef hyperspectral images were mosaicked together and principal component (PC) analysis was conducted to reduce the spectral dimension. Six different textural feature ...
