Effects Of 50:50 Proportion Bull:Cow Blend Levels And Incorporation Of Finely Textured Beef On The Color Of Precooked Ground Beef Patties, Colton Allen Althaber
Effects Of 50:50 Proportion Bull:Cow Blend Levels And Incorporation Of Finely Textured Beef On The Color Of Precooked Ground Beef Patties, Colton Allen Althaber
Graduate Theses and Dissertations
Variation in internal cooked color of ground beef is an economic concern for the ground beef market. Persistent pink color in hamburger patties can lead consumers to the perception of an undercooked product. Therefore, the objective of this study was to characterize the effects of bull:cow blend proportions, with or without finely textured beef (FTB), and cookery method on internal color of precooked ground beef patties. Batches (9.1 kg) of 85% lean ground beef were manufactured with 0, 33, 67, or 100% 50:50 bull:cow blend (remainder of lean was 100, 67, 33, or 0% Select-grade knuckles, respectively) mixed with 2 …

The Physicochemical Properties Of Soy Protein Hydrolysate And Its Formulation And Stability With Encapsulated Probiotic, John Stricklin Edwards
Graduate Theses and Dissertations
Soy protein isolate (SPI) and probiotics can serve as a functional ingredient and beneficial supplement, respectively, to food formulations, but few studies focus on the compatibility of these two ingredients. The objective of this study was to prepare soy protein isolate (SPI) from defatted soybean flour and identify an optimal hydrolysis protocol to create soy protein hydrolysates (SPH) with improved solubility and functional properties and achieve an optimum encapsulation technique for probiotics and to determine the in vitro viability of encapsulated probiotic cells with SPH in a gastrointestinal environment. The SPI was prepared using an alkaline extraction procedure for solubility …
Impacts Of Size Fractionation And Processing On Functional Characteristics Of Broken Rice Kernels, Rebecca Mawusi Bruce
Impacts Of Size Fractionation And Processing On Functional Characteristics Of Broken Rice Kernels, Rebecca Mawusi Bruce
Graduate Theses and Dissertations
Rice flour generated from broken rice (brokens) has inconsistencies in functional properties. This may be due to differences in size and composition of brokens used for the flour. It is postulated that size classification of brokens can improve flour functionality. This study sought to investigate the effect of size fractionation of brokens on the functional or pasting properties of resulting rice flour. Broken rice was generated from six cultivars of freshly harvested rough rice that were dried at 25◦C in the laboratory. The brokens were classified into large, medium and small, using US sieve size 10, 12 and 20 respectively. …
Impact Of Sanitizers On Salmonella Enterica Contamination And Microbial Populations Of Poultry Processing Reuse Water, Andrew Micciche
Impact Of Sanitizers On Salmonella Enterica Contamination And Microbial Populations Of Poultry Processing Reuse Water, Andrew Micciche
Graduate Theses and Dissertations
As human populations increase in numbers, access to clean, fresh water is becoming increasingly difficult to balance between agricultural and municipal demands. Water scarcity is a limiting factor of food production in many countries, whether they are emerging or established economies. In conventional poultry processing systems, access to water is particularly critical for the maintenance and disinfection of processing areas, as well as in processing operations such as scalding, chilling, and carcass washing. The need for sustainable alternatives to single-use water supplies is becoming increasingly more urgent, and as a result, the implementation of water reuse in poultry processing plants …
Effects Of Germination Conditions Of Brown Rice In Relation To Flour Physicochemical Properties And Bread Qualities, Wipada Wunthunyarat
Effects Of Germination Conditions Of Brown Rice In Relation To Flour Physicochemical Properties And Bread Qualities, Wipada Wunthunyarat
Graduate Theses and Dissertations
Gluten-free products from rice are gaining popularity among consumers because of its hypoallergenic characteristic. The absence of gluten results in inferior bread qualities such as hard texture, reduced volume and shorter shelf-life, which can be improved by the addition of external hydrolytic enzymes. Hydrolytic enzymes are activated during germination to stimulate plant growth, and hence these enzymes may function similarly to the external enzymes to improve gluten-free bread from brown rice. Therefore, the objective of this work was to investigate the activities of amylases and protease in germinated brown rice (GBR) from long-grain and short-grain rices under different germination conditions …

Potential Antimicrobials For Controlling Listeria Monocytogenes In Frankfurters, Aaron Rashad Bodie
Potential Antimicrobials For Controlling Listeria Monocytogenes In Frankfurters, Aaron Rashad Bodie
Graduate Theses and Dissertations
Listeria monocytogenes is a pathogenic microorganism that causes Listeriosis. Listeriosis is a highly mortal disease with approximately 20% mortality rate. Listeria is psychrophilic, therefore it is able to survive in the refrigerator. This affects foods at cool storage such as fresh produce and RTE meats. To ensure the safety of RTE meat, post processing treatments are used such as vacuum packing, edible films, dip and treatment. One-way RTE can be treated is with the use of antimicrobials. However, in the past chemical substances were used. Currently, consumers want more natural and organic preservatives to combat health problems from toxic components …
Implications Of Rice Cultivar Selection To Optimize Returns From Crop Insurance, David Ethan Branscum
Implications Of Rice Cultivar Selection To Optimize Returns From Crop Insurance, David Ethan Branscum
Graduate Theses and Dissertations
Rice production differs from most other field crops by distinct differences in yields across cultivars and rice producers being paid for yield after post-harvest milling. Using eleven years (2003-2013) of Arkansas harvest data from performance trials in six different locations, hybrids have 19% higher paddy yields and head rice yield rate 1.7% lower than conventional cultivars. Given the 2014 Farm Bill’s emphasis on crop insurance as a risk management tool for producers, these variations in yield among cultivars have significant implications for rice producers. Comparing national level, crop insurance data on corn, soybeans and rice indicates rice producers strongly prefer …
Concentration Of Hot Water Extracts Of Anthocyanins Obtained From Muscadine Grape Pomace Using Membrane-Osmotic Distillation, Chuqiao Mai
Food Science Undergraduate Honors Theses
Anthocyanins are well known for their health-promoting benefits. The goal of this study was to evaluate a distillation-based membrane technology to concentrate aqueous anthocyanins extracted from muscadine grape pomace using polypropylene (PP) or ethylene chlorotrifluoroethylene (ECTFE) membranes. A hot water extraction method was utilized to extract the anthocyanins from the pomace. A pre-experimental run using DI water as feed was conducted to optimize the NaCl brine concentration for osmotic distillation and it was determined that 4M was the optimal concentration. The aqueous anthocyanins extraction was filtrated through a series of filter of different pore sizes before the distillation process. Membrane …
