Donating Safe And Wholesome Food, Brian Nummer, Paula Scott

All Current Publications

Americans dispose of millions of pounds of tons of food, and the U.S. Department of Agriculture estimates that 11.8 percent of American households, or about 15 million, had difficulty providing enough food for all their family members (Coleman-Jensen et al., 2018). Much of the food disposed into landfills is wholesome and edible. This fact sheet outlines how a potential food donor can get started and get food into the hands of the needy.

The Thermal And Physical Properties Of Beef From Three Usda-Quality Grades Cooked To Multiple Degrees Of Doneness, Jessica Mcclellan Hadfield Aug 2019

The Thermal And Physical Properties Of Beef From Three Usda-Quality Grades Cooked To Multiple Degrees Of Doneness, Jessica Mcclellan Hadfield

All Graduate Theses and Dissertations

The objective of this study was to determine the influence of quality grade (QG) and degree-of-doneness (DOD) on thermophysical properties of beef strip steaks. The “Prime” eating experience must be marketed to compete with cheaper protein sources, and so palatability is a major concern with beef products. Thermal and physical properties help shed light on the impacts various components have on beef palatability, mainly tenderness and juiciness. Warner-Bratzler shear force (WBSF) and the textural property of springiness are both influenced by a combination of QG and DOD. This is also true for viscoelasticity and the degradation of myosin and sarcoplasmic ...

Growth Characteristics Of Lactobacillus Wasatchensis And Its Detection And Enumeration Using Quantitative Polymerase Chain Reaction, Isaac Brockbank Bowen

All Graduate Theses and Dissertations

There are numerous challenges encountered during the manufacturing and storage of cheese by both the large-scale and artesian producers. One such challenge has been the formation of late gassy defect, which occurs when gas is produced by certain lactic acid bacteria found in the cheese block during storage and aging over a three month time period. Negative consequences of late gas production are slits and cracks in the cheese block and puffy cheese packaging, which cause significant financial losses for manufacturers along with poor consumer acceptance.

Lactobacillus wasatchensis is one such lactic acid bacterium shown to produce gas during cheese ...

Whole Cell Cross-Linking To Discover Host-Microbe Protein Cognate Receptor/Ligand Pairs, Bart C. Weimer, Poyin Chen, Prerak T. Desai, Dong Chen, Jigna Shah Jul 2018

Whole Cell Cross-Linking To Discover Host-Microbe Protein Cognate Receptor/Ligand Pairs, Bart C. Weimer, Poyin Chen, Prerak T. Desai, Dong Chen, Jigna Shah

Biological Engineering Faculty Publications

Bacterial surface ligands mediate interactions with the host cell during association that determines the specific outcome for the host–microbe association. The association begins with receptors on the host cell binding ligands on the microbial cell to form a partnership that initiates responses in both cells. Methods to determine the specific cognate partnerships are lacking. Determining these molecular interactions between the host and microbial surfaces are difficult, yet crucial in defining biologically important events that are triggered during association of the microbiome, and critical in defining the initiating signal from the host membrane that results in pathology or commensal association ...

Applied Sciences, Technology and Education Faculty Publications

Worldwide, food waste is one of the prime issues threatening food security and the Kingdom of Saudi Arabia (KSA) is not an exception. With 427 kg of food wasted per capita per year, the country ranks among the top food wasters. Ironically, the Kingdom has limited arable lands and scarce water resources to support mass-scale agriculture and to feed its increasing population, KSA relies heavily on imports and subsidized food to meet needs. Yet, food is wasted at restaurants, caterers, cafeterias and, especially, by households such that food waste is the single-largest component of the landfills. The review article is ...

Characterization Of Lactose Fatty Acid Esters For Their Microbial Growth Inhibitory Activity And Emulsification Properties, Seung-Min Lee

All Graduate Theses and Dissertations

Sugar esters, substances made from bonding fatty acid tails to a sugar head, can play a number of key roles in food systems from antimicrobial agents to emulsifiers. These unique and very useful properties result from their water-loving and water-avoiding ends. Lactose, a sugar found in milk, based esters are important, as they are environmentally friendly and inexpensive, however, they are not very well understood. I created four different types of lactose esters: lactose monooctanoate (LMO), lactose monodecanoate (LMD), lactose monolaurate (LML) and lactose monomyristate (LMM), and then compared them to each other to see which would be the best ...


Effect Of High Intensity Ultrasound On The Crystallization Behavior Of Interesterified Fats, Jeta Vijay Kadamne May 2018

Effect Of High Intensity Ultrasound On The Crystallization Behavior Of Interesterified Fats, Jeta Vijay Kadamne

All Graduate Theses and Dissertations

The process of partial hydrogenation produces trans fats and the fats that undergo this process are called partially hydrogenated fats (PHF). Clinical studies have shown a strong association between PHF and coronary heart diseases. In 2015 The U.S. Food and Drug Administration removed the Generally recognized as safe or "GRAS" status of PHF. These fats were used in confectionary, margarines, shortenings, doughnuts, cookies, cakes, etc. The PHF serve a function in food by providing a higher shelf life and a desired harder structure due to their higher melting point. Hence, the food industry is currently looking for PHF alternatives ...
