“Red Light, Yellow Light!”: Evaluating the Anti-Listerial Potential of Bacillus Isolate Metabolites Using a High-Throughput Chromogenic Assay”

Creator:: Johnson, Taylor S.
Abstract:: Listeria monocytogenes contamination continues to pose challenges for the food industry and there is demand for effective methods of food preservation and protection that can also be considered clean label. A promising source of antilisterial compounds may be sourced from bacteria that produce novel byproducts. Ribosomally synthesized and post-translationally modified...

Bovine Kappa-Casein Glycomacropeptide: Its Effects on the Microbiome, Inflammation and the Potential in Irritable Bowel Syndrome Management

Creator:: Qu, Yunyao
Abstract:: Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder experienced by 10–15% of the global population, manifesting as chronic abdominal pain, bloating and inconsistent bowel habits. The search for effective treatments remains ongoing. One promising contender in this realm is kappa-casein glycomacropeptide (GMP), a milk-derived peptide. Its potential benefits stem...

Immunomodulatory Actions of Bovine Whey Protein Isolates, Glycomacropeptide, and Their Digests: Insights from Macrophage and Human Studies

Creator:: Olsen, Wyatt
Abstract:: Whey protein isolate (WPI) and glycomacropeptide (GMP) have shown potential immunomodulatory properties. In this study, we investigated their effects on pro-inflammatory cytokine secretion using both in vitro and in vivo models. In LPS-stimulated THP-1-derived macrophages, digested WPI and GMP reduced cytokine expression, while whole GMP increased secretion. The in human...

Anti-obesity and Metabolic Health Impact of Pacific Dulse (Devaleraea mollis) and Nori (Pyropia spp.) Seaweeds in Western Diet-Induced Obese C57BL/6J Mice

Creator:: Zhou, Leyi
Abstract:: Seaweeds have gained tremendous recognition as a highly nutritious and sustainable crop. The diverse components of seaweeds are known to exhibit a wide range of bioactivities, including anti-inflammatory, anti-diabetic, and cardiovascular health benefits. One such promising seaweed is Pacific dulse (Devaleraea mollis). While it holds great cultivating potential on the...

Effects of Whey Protein Consumption on Inflammatory Biomarker Levels in Healthy Older Adults

Creator:: Adler, Samuel
Abstract:: Whey protein’s potential for bioactivity is well documented, but there is disagreement on the extent to which it may modulate the immune system towards decreased inflammation. Decreased inflammation is generally perceived as a beneficial bioactivity in foods as excessive chronic inflammation is linked to morbidity and mortality. This thesis first...

Tropical Fruit Aroma in Chardonnay: Impact of Fermentation Techniques on Volatile Ester and Thiol Concentrations, Tropical Fruit Aroma Perception, Preference, and Emotional Response

Creator:: Lucas, Chase J.
Abstract:: Tropical fruit aromas are prominent in wines like Sauvignon Blanc, one of the most abundant white wines in the United States. With high consumer interest for these aromas, it has become increasingly important to understand the factors that influence the desired tropical fruit aromas in white wines. Understanding the causes...

Identification of Bitter Peptides in Aged Cheddar Cheese

Creator:: Kuhfeld, Russell
Abstract:: Bitterness is a common flavor attribute of aged cheese, but excessive levels are a flaw leading to consumer rejection. Bitterness in cheese has been primarily associated with milk casein-derived peptides of medium size (500–3,000 Da) and relative hydrophobicity. Herein, we demonstrate a novel approach for the identification of bitter peptides...

Cleaning and Sanitizing Surfaces on Produce Farms: Optimizing What, How, and When

Creator:: Ohman, Erik
Abstract:: Production of fresh produce takes place outdoors, and therefore, is exposed to many routes of contamination (e.g., soil, contaminated water, manure, etc.) by human pathogens. Although precautions are taken to reduce this risk, pathogens can be regularly introduced to produce handling facilities. To manage the risk of cross-contamination from potentially...

Elucidating the Patterns of Cooccurrence, Spatial Structuring, and Impact on Fermentation Metabolism in Kombucha Microbial Communities

Creator:: Harrison, Keisha Rose
Abstract:: This dissertation investigates the microbial diversity and factors influencing the assembly of microbial communities in kombucha production, using a combination of 1H Nuclear Magnetic Resonance Spectroscopy, 16S and ITS rRNA metabarcoding, and traditional culture-based microbiological methods. It also explores the diversity of kombucha starter cultures through shotgun sequencing and metabarcoding...

An Exploration of Cheese Safety Parameters and Aging as Mitigation Strategy for Foodborne Pathogens in Cheese

Creator:: Riesgaard, Brandon
Abstract:: Pasteurization is an effective method of reducing risks associated with foodborne pathogens in raw milk. Cheese made from raw milk has a higher potential to harbor harmful bacterial pathogens. However, some cheesemakers prefer to use unpasteurized milk to preserve the natural microflora present in the raw milk and to prevent...
