The Elimination Of Listeria Monocytogenes Biofilms From Stainless Steel Deli Meat Slicer Components By The Use Of Hurdle Technologies, Alexandria Wynne Mertz Dec 2014

The Elimination Of Listeria Monocytogenes Biofilms From Stainless Steel Deli Meat Slicer Components By The Use Of Hurdle Technologies, Alexandria Wynne Mertz

Graduate Theses and Dissertations

Listeria monocytogenes growth is of the greatest concern amongst ready-to-eat foods. The United States Department of Agriculture's Food Safety and Inspection Services determined that deli luncheon meats pose the greatest risk of contamination from L. monocytogenes Industrial meat slicers have many removable parts that are connected with sealers and gaskets, which can become worn over time. These spaces cannot be cleaned adequately, therefore are susceptible to bacterial growth. Planktonic cells form biofilms in order to protect the cell from adverse conditions, like during routine cleaning and sanitation. Once a biofilm is formed, the bacteria are much more difficult to eradicate …


Changes In Monomeric And Polymeric Pigments During Chokeberry Juice Processing, Kail David Wilkes Dec 2014

Changes In Monomeric And Polymeric Pigments During Chokeberry Juice Processing, Kail David Wilkes

Graduate Theses and Dissertations

Chokeberry consumption has been increasing due to research exposing great potential of health-promoting compounds. However, chokeberries are highly astringent and are typically consumed in processed forms in which product heating is applied. Processing chokeberries has been reported to degrade bioactive compounds, thus limiting the potential for consumers to obtain their health-promoting benefits. The purpose of this research was to examine the effects of chokeberry juice processing and storage on anthocyanin, flavonol, proanthocyanidin, hydroxycinamic acid, and polymeric pigment content, as well as percent polymeric color. In addition, new analytical methodologies were explored to better understand possible outcomes of polymeric pigments due …


Effect Of Limit-Fed Co-Product Feedstuffs On Production, Digestion, Fermentation And Rumen Function In Beef Cattle, William Brandon Smith May 2014

Effect Of Limit-Fed Co-Product Feedstuffs On Production, Digestion, Fermentation And Rumen Function In Beef Cattle, William Brandon Smith

Graduate Theses and Dissertations

In terms of energy density, the cost of shipping hay is often not justified in yr where adverse conditions limit available forage. Our objective was to determine if co-product feedstuffs could be used to meet the energy demands for cows in late pregnancy. Eighty-six crossbred cows (527 ± 0.8 kg BW) in late gestation were stratified by BW, BCS and age and allocated randomly to 1 of 6 groups held on 2-ha dormant bermudagrass pastures for 68 d. Three groups were offered bermudagrass hay ad libitum (HAY) and three groups were offered 6.4 kg of soybean hulls (LSH) daily and …


Milling And Functional Properties Of Co-Mingled Rice Cultivars, Nikhil N. Basutkar May 2014

Milling And Functional Properties Of Co-Mingled Rice Cultivars, Nikhil N. Basutkar

Graduate Theses and Dissertations

Differences have been observed in the milling and functional properties of different rice cultivars, particularly between hybrid and pureline cultivars. Co-mingling of rice cultivars commonly occurs during harvest, storage and drying operations. Thus, there is a need to study the effect of co-mingling on the milling and functional properties of rice cultivars. Two long-grain, hybrid (H) cultivars CL XL745 and CL XL729 and two long-grain, pureline (P) cultivars CL 151 and Wells were used to prepare CL XL745/CL 151 (H/P), CL XL745/CL XL729 (H/H) and Wells/CL 151 (P/P) co-mingles, mixed in various proportions. Milled rice yield (MRY), head rice yield …


Stability Of Nano-Encapsulated Rice Bran Derived Bioactive Pentapeptide In Apple Juice, Fatima Mohammed Alessa May 2014

Stability Of Nano-Encapsulated Rice Bran Derived Bioactive Pentapeptide In Apple Juice, Fatima Mohammed Alessa

Graduate Theses and Dissertations

Cereal grains and their components derived Bioactive compounds such as rice bran can promote health and can be derived from Rice bran contains 12-20 % protein and could be a good source for extracting bioactive peptides. A pentapeptide with a secqunce of amino acids Glu-Gln-Arg-Pro-Arg (EQRPR) has been prepared from heat stablized defatted rice bran (HDRB) and has demonstrated anti-cancer proprerties in-vitro. This bioactive pentapeptide can thus be used as a nutraceutical by incorporating it into a suitable food system. Fruit juces can be vehicles to incorporate this pentapeptide. Fruit juices contribute to about 60% of the consumed beverages in …


College Students’ Perceptions Regarding Sensory Aspects Of Conventionally Produced And Unconventionally Produced Foods: Implications For Marketing To The Millennial Generation, Christina Crowder, Catherine W. Shoulders, K. Jill Rucker Jan 2014

College Students’ Perceptions Regarding Sensory Aspects Of Conventionally Produced And Unconventionally Produced Foods: Implications For Marketing To The Millennial Generation, Christina Crowder, Catherine W. Shoulders, K. Jill Rucker

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Consumers vote every day on which products line the shelves of grocery stores, co-ops, and niche markets. Public unrest with regard to the environmental, animal welfare, food purity, and human health impacts of agricultural production practices have led to the rise of unconventionally produced (UP) food products. While the sales of UP foods is increasing, studies regarding the qualities of such products that impact consumer purchases have yielded inconsistent results. This study examined students’ perceptions of sensory aspects of conventionally produced (CP) and UP foods to better understand how sensory aspects impact decisions to purchase. Students reported consistent perceptions regarding …
