Ensuring Microbial Safety In Food Product/Process Development: Alternative Processing Of Meat Products And Pathogen Survival In Low-Salt Cheddar Cheese, Subash Shrestha
Ensuring Microbial Safety In Food Product/Process Development: Alternative Processing Of Meat Products And Pathogen Survival In Low-Salt Cheddar Cheese, Subash Shrestha
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Most outbreaks of foodborne illness in the United States occur as a result of improper food-handling and preparation practices in homes or food establishments. The lack of food-safety knowledge is one of the several reasons for this. However, researchers also suggest that food-operators and consumers with adequate food-safety knowledge, attitudes, and intentions do not always follow the food-safety recommendations because not all recommendations are easy to put into practice. Therefore, the first part of this study sought to establish safe alternative processing of meat products that can be easily practiced by food-operators and consumers. In Chapter 3, a novel method …
Evaluation Of Levulinic Acid For Topical Decontamination Of Meat Surfaces, Jeffrey V. Smith
Evaluation Of Levulinic Acid For Topical Decontamination Of Meat Surfaces, Jeffrey V. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Experiments were performed to investigate the effects of wash treatments, consisting of hot water, 2% lactic, 2% acetic, or 2% levulinic acid, for decontamination of pathogenic bacteria previously inoculated onto meat surfaces, to inhibit growth of pathogenic bacteria inoculated onto previously washed meat surfaces, and on the organoleptic quality of sliced turkey roll and beef trim. Acid washes were no more effective at reducing Escherichia coli O157:H7 on beef plate, Listeria monocytogenes on sliced turkey roll, and Salmonella on pork belly than was water wash. Only lactic acid treatment was more effective than water at reducing Salmonella on chicken skin, …
Control Of Listeria Monocytogenes In Ready-To-Eat Meat Containing Levulinate, Lactate, Or Lactate And Diacetate, Rebecca L. Thompson
Control Of Listeria Monocytogenes In Ready-To-Eat Meat Containing Levulinate, Lactate, Or Lactate And Diacetate, Rebecca L. Thompson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Control of the pathogen Listeria monocytogenes in ready-to-eat (RTE) meats is a major concern in the food industry. The objective of this study was to compare the growth of L. monocytogenes on refrigerated RTE meats containing sodium levulinate (4-oxopentanoic acid, a five carbon organic acid with GRAS status), sodium lactate, or a combination of sodium lactate and sodium diacetate. Turkey roll and bologna were prepared to contain (wt/wt) sodium lactate (2%); sodium lactate in combination with sodium diacetate (1.875% sodium lactate, 0.125% sodium diacetate); sodium levulinate (1, 2, or 3%); or no antilisterial additive. Samples were sliced, inoculated with a …
The Contribution Of Meats To Energy And Essential Nutrient Intakes Of Women In The United States, C. Dian Martin
The Contribution Of Meats To Energy And Essential Nutrient Intakes Of Women In The United States, C. Dian Martin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study used the 1987-88 USDA Nationwide Food Consumption Survey to investigate the contribution meat products make to intakes of nutrients at risk of inadequate or excessive consumption by women. The study is unique in that meat nutrients were extracted from mixed dishes, providing a more accurate picture of consumption. Cluster analysis was used to classify nonpregnant, nonlactating women 19 years and older based on their consumption patterns of total meat and individual meats (beef, poultry, processed meats, pork and seafoods) as percent of caloric intake.
Total fat and SFA intakes exceeded National Research Council (NRC) goals regardless of meat …
The Bioavailability Of Iron From Meat, Spinach, Soy Protein Isolate, Meat:Spinach And Meat:Spi Mixtures Fed To Anemic And Healthy Rats, Dejia Zhang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two Experiments were conducted to investigate the effect of iron status and iron source on iron bioavailability using the rat model. Beef was proportionally mixed with spinach (Experiment I) or soy protein isolate (Experiment II) to test if meat enhances the absorption of iron from spinach or SPI. Five diets with the iron from meat:spinach (or SPI) ratios of 100:0, 75:25, 50:50, 25:75 and 0:100 were prepared and fed to rats. FeS04 was used as a reference. Two trials of rats were used in Experiment I. In trial I, half of the rats were made severely iron deficient (Hb 6.3 …
Iron Bioavailability Of Meat:Bread Mixtures And Meat Loaves Fed To Anemic And Healthy Rats, Abdullah M. Thannoun
Iron Bioavailability Of Meat:Bread Mixtures And Meat Loaves Fed To Anemic And Healthy Rats, Abdullah M. Thannoun
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
To study the effect of meat (beef) on dietary iron bioavailability from enriched white bread (EWB) or whole wheat bread (WWB), diets were prepared in which the ratios of beef iron to bread iron were 100:0, 75:25, 50:50, 25:75 or 0:100. Hemoglobin regeneration efficiency (HRE), apparent iron absorption, and dry matter absorption were determined using weanling anemic and healthy male rats.
Meat iron was more available than EWB or WWB. Fortification iron in EWB was less available than the iron naturally present in WWB. At the iron dose given, HRE was similar for both anemic and healthy rats. Although healthy …
Effect Of Processing On Aliphatic Aldehyde Content Of Turkey Meat, Carolyn G. Ponce
Effect Of Processing On Aliphatic Aldehyde Content Of Turkey Meat, Carolyn G. Ponce
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nitrite at the level found in turkey frankfurter formulations vii did not interfere in the hydrazone test as developed by Andrews (1975). The aldehyde levels of frankfurters made principally from MD turkey meat were, on the average, twice as high as the levels in the raw meat. Aldehyde levels generally increased as the frozen storage time of the raw meat increased. There were some variations from this trend due to variation in the fat content of the raw meat. Sixty days was recommended as a maximum frozen storage time. However, because of variation in the fat content from sample to …
A Comparative Gas Chromatographic Study Of Venison And Beef Flavors, K. Prakash Reddy
A Comparative Gas Chromatographic Study Of Venison And Beef Flavors, K. Prakash Reddy
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Venison is an important food item in the diet of the people of the United States. Deer is hunted both as sport and for food. Annually, nearly 180,000 hunters go afield in Utah in search of deer. Over 130,000 animals are killed which amounts to an annual harvest of over 15,000,000 pounds of dressed venison. This contributes about 10 1/2 million dollars to the economy of the state from licenses, lodgings, transportation, and other expenses of hunting.
