Research outputs 2014 to 2021

The safety of oats for people with celiac disease remains unresolved. While oats have attractive nutritional properties that can improve the quality and palatability of the restrictive, low fiber gluten-free diet, rigorous feeding studies to address their safety in celiac disease are needed. Assessing the oat prolamin proteins (avenins) in isolation and controlling for gluten contamination and other oat components such as fiber that can cause non-specific effects and symptoms is crucial. Further, the avenin should contain all reported immunogenic T cell epitopes, and be deliverable at a dose that enables biological responses to be correlated with clinical effects. To …

Consumer Perceptions Of Labeling Claims On Poultry Products, Sarah Townley

Agricultural Education, Communications and Technology Undergraduate Honors Theses

An increasing number of consumers wants more knowledge of how the food they eat is produced, and specifically, how animals used in the production of their food are raised. One method consumers use to become more aware of production practices behind the food they purchase and consume is simply reading food labels. Labeling claims can be defined as textual, pictorial, graphic, or symbolic representation that either explicitly states or implies that a food product has a specific set of properties supported by a certification process. The purpose of this study is to gather data regarding consumer knowledge and understanding of …

Fuller Together: An Understanding Of The Nexus Between Disability And Food Security, Zach Curinga

Public Health, Food Studies, and Nutrition

American society is currently structured to function for those individuals bestowed with inherent abilities. As such, it ignores access to participate socially and culturally for those who are disabled. There is a trend that elected representatives often limit access of the socio-cultural rights of others who are unlike themselves, interpreted by their own personal, non-disabled, socioeconomic experience. This trend is the root of the problem for those who are disabled: they cannot access and participate in society fully, which makes them often disregarded by their representatives who do not face their same barriers.

In this thesis, I apply a human …

Agro-Industrial Lignocellulosic Biomass: A Sustainable Platform For The Production Of Α-Amylase And Xylanase A, Rajeev Ravindran

Doctoral

Enzymes such as α-amylase and xylanase offer potential for numerous industrial applications such as food, beverage, and animal feed production, detergents, textile, cosmetics and biodiesel production. Economic factors such as achievement of optimum yields and production cost are the main deterrents in the industrial use of these enzymes. Enzymes are generally produced via microbial fermentation using expensive mediums which account for 30 to 40% of the production cost. Food industry wastes such as spent coffee waste (SCW) and Brewers’ spent grain (BSG) are two of the most common food waste products expelled by the food and beverage industry here in …

Development Of A Methodology For Predicting Consumer Acceptance And Preference Toward Beverages, Shilpa Shailesh Samant

Graduate Theses and Dissertations

Consumer behavior toward food/beverages is influenced by multisensory attribute perceptions as well as emotional experiences. Traditional methods of sensory testing lack the ability to capture emotional responses and as a result, measuring food/beverage-evoked emotions remains a research challenge. There were three objectives of this dissertation study. Firstly, this study aimed to develop prediction models of acceptance of and preference for basic taste solutions using sensory attribute intensities and emotional responses. Secondly, this study aimed to extend the findings of the first objective to develop prediction models of commercially-available vegetable juice products in terms of (a) acceptance and preference under blind-tasting …

Efficacy Of Antimicrobial Mitigation On Escherichia Coli Cfu And Growth And Development Of Hydroponic Leafy Greens, Nathan J. Eylands

Graduate Theses and Dissertations

The Food and Drug Administration (FDA) have set new standards that apply to agriculturalists producing crops eaten fresh and/or raw by consumers. This new produce safety rule, known as the Food Safety Modernization Act (FSMA), has established science-based standards for all areas of production in agriculture with regards to microbial contamination. Escherichia coli (E. coli) O157:H7 is a particular bacterium of concern under FSMA guidelines. Grower compliance is mandatory and therefore vital to the continuation of any farm. Greenhouse hydroponic growers have shown advantages in efficiency when compared to conventional farming methodology. Those, however, with recirculating hydroponic systems face unique …

Efficacy Of Natural Compounds With Novel Carrier Systems For Controlling Campylobacter Jejuni In Post-Harvest Poultry, Sandip Shrestha

Graduate Theses and Dissertations

Campylobacter jejuni, a leading cause of bacterial gastroenteritis worldwide, is strongly associated with the consumption and/or mishandling of raw contaminated poultry products. Thus, interventions aiming to reduce C. jejuni counts on poultry products could greatly reduce the incidence of human campylobacteriosis. In the first study, the efficacy of a generally recongnized as safe (GRAS) compound, carvacrol (CR; derived from oregano oil), as an antimicrobial wash treatment to reduce C. jejuni on chicken skin was evaluated. Three delivery systems of CR: suspension, emulsion and nanoemulsion were used. C. jejuni counts were reduced up to 4 log10 cfu/sample by 2% dose of …
