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 …

Pharmaceutical Sciences Faculty Publications

Although the effects of nano-sized titania (nTiO₂) on hatching events (change in hatching time and total hatching) in zebrafish have been reported, additional consequences of nTiO₂ exposure (i.e., the effects of nTiO₂-induced changes in hatching events and morphometric parameters on embryo-larvae development and survivability) have not been reported. To address this knowledge gap, embryos 4 h postfertilization were exposed to nTiO₂ (0, 0.01, 10, and 1000 μg/mL) for 220 h. Hatching rate (58, 82, and 106 h postexposure [hpe]), survival rate (8 times from 34 to 202 hpe), and 21 morphometric characteristics (8 times …

Assessment Of Salmonella Enterica Biofilms And Expression Differences Among Serovars, Zhaohao Shi

Graduate Theses and Dissertations

Biofilms are communities of microorganisms associated by a matrix of extracellular polymers. In this state, microorganisms occupy an ecological niche distinct from their free-floating, planktonic counterparts. Also, biofilm bacteria become biologically unique as they form communities and lose motility. The acquisition of these physiological attributes enables the biofilm to persist through harsh environmental conditions, including antimicrobial induced stress and to resist sanitization efforts. Because of these features, biofilms can rapidly disseminate across numerous surfaces and as they establish, become challenging to remove. This is a particular issue for the food industry as processing plants offer favorable conditions for biofilm formation …

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 …

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 …

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 …

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 …

Microbiota Metabolic Product Deoxycholic Acid Prevents Campylobacter Jejuni Chicken Colonization Through Modulating Ceca Anaerobes, Bilal Ali Alrubaye

Graduate Theses and Dissertations

Campylobacter jejuni is a prevalent infectious enteritis mainly foodborne from chickens. Despite of reducing C. jejuni food contamination dramatically decreases campylobacteriosis, few effective approaches are available for the bacterial reduction in chickens. The aim of this study was to use microbial metabolic product deoxycholic acid (DCA) to reduce C. jejuni chicken colonization. Broiler chicks were fed 0 or 1.5 g/kg DCA, lithocholic acid (LCA), or urodeoxycholic acid (UDCA) in diets or orally gavaged with cholic acid (CA, 1.5g/kg body weight). Birds were also transplanted with DCA modulated anaerobes (DCA-Anearo) or aerobes (DCA-Aero). Birds were infected with 109 CFU/bird human clinical …

Energy And Water Assessment And Plausibility Of Reuse Of Spent Caustic Solution In A Midwest Fluid Milk Processing Plant, Carly Rain Adams

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The Food Energy and Water Nexus (FEW Nexus) is the inseparable connection linking these resources. The concept of the FEW Nexus within the food industry addresses the connection of water and energy as key members of food production. The steady increase in population and the increase in food demand are directly related, therefore, the need for water and energy. Immediately taking on this critical challenge will lead to tangible impacts on the water and energy crisis facing the food system. To reduce the distance between process productivity and resource efficiency it must first be determined, within food processing, where water …
