Single-Laboratory Validation For The Detection Of Salmonella Enterica In Meat Analog Products, Amanda Tabb
Food Science (MS) Theses
Meat analogs are becoming increasingly popular for health, environmental, and ethical reasons. However, these products are at risk for contamination with Salmonella enterica. Therefore, it is important to ensure that detection methods for S. enterica in meat analog products are effective. Currently, the Bacteriological Analytical Manual (BAM) chapter on Salmonella detection calls for pre-enrichment of meat analogs using lactose broth (LB) with added surfactants, Tergitol Anionic 7 or Triton X-100. However, it remains to be determined whether surfactants are necessary for pre-enrichment of meat analogs. Following pre-enrichment, screening with VIDAS is typically performed. While VIDAS is an effective screening method, …

Kinetic And Mass Spectrometric Characterization Of Anti-Greening Mechanisms Of Cysteine And Glutathione In Chlorogenic Acid-Lysine Solutions, Charles Taylor Drucker
Food Science (MS) Theses
Effective decolorization methods mitigating green compound formation from alkaline chlorogenic acid-amino acid reactions can facilitate greater consumption of chlorogenic acid-rich products. While thiols show promise as decolorization agents to replace sulfites, their application has not been optimized. In this work, cysteine and glutathione were probed for their varying kinetic effects on the onset of chlorogenic acid-lysine induced greening. A six-parameter model developed from a reparametrized Weibull cumulative distribution function accurately captured the time- and thiol concentration-dependence of greening in chlorogenic acid-lysine-thiol solutions at pH 8.0 and 9.0, illustrating the pH-dependence of each thiol’s effectiveness at lowering terminal greening magnitude as …

Use Of Protective Lactic Acid Bacteria Adjunct Cultures To Decrease The Incidence Of Gas Defects In Cheddar Cheese, Rhees T. Crompton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Gas production in cheese making is becoming increasingly prevalent in the dairy industry. This gas is produced by microbes that are naturally found in the cheese, and when they metabolize sugar or other sources of energy, they can produce gas. This gas causes slits and cracks in the cheese, which causes the cheese to be worth less and causes issues during slicing and shredding. There are many microbes that cause unwanted gas in cheese, this research focuses on four know gas producers and five other protective microbes that use the same energy sources or have the ability to inhibit the …

Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Graduate Theses and Dissertations
Porous starch produced by enzyme hydrolysis has attracted much attention for its adsorption and delivery properties. Porous starch has been successfully prepared from A-type starch, but not from B-type and C-type starches, which is partly attributed to the surface and crystalline structure. The present study aimed to characterize the role of the crystalline structure and the structure-function relationship impacting the susceptibility of starch with different crystalline polymorphs to amylase digestion. The starches were subjected to chemical modification (acid hydrolysis or surface gelatinization), physical modification (heat-moisture treatment, HMT, or high-pressure processing, HPP) or their combinations prior to amylase digestion, and the …

Potential Control Of Invasive Mesquite Through Improving The Consumer’S Understanding Of Liquid Smoke Applications., Seth W. Ellsworth
Graduate Theses and Dissertations
Mesquite trees continue to invade forests and range lands in many countries across the world. The cost to remove these trees is staggering. In Texas, landowners spent $25 million over a 10- year period to clear 300,000 ha of mesquite trees, a fraction of the 22 million ha of Texas land affected by this invasion. Estimates are that the mesquite continues to negatively impact one to two percent of additional land in selected counties each year in Texas. However, the problem is not unique to Texas, but rather to the 44 species of mesquite trees, belonging to the genus Prosopis …
