Effects Of Fermented Soybean Products On The Human Gut Microbiome, Microbial Metabolism, And Host Physiology, Shannon Moncier

Biology Dissertations

Fermented soybean products (FSPs) contain soybean-derived substrates, fermentation-associated microorganisms, and bioactive compounds that may interact with the human gut microbiome and host physiology. However, despite the growing interest in FSPs, longitudinal human studies specifically evaluating traditional Korean-FSPs (K-FSPs), particularly among United States-based populations, remain limited. The objective of this work was to evaluate the effects of three K-FSPs, including Cheonggukjang, Gochujang, and Doenjang, on host physiological responses, gut microbial community structure, predicted microbial functional potential, and fecal butyrate responses in healthy adults. Three independent dietary intervention cohorts were conducted using FSP formulations produced either by traditional artisan methods (Product A) …

Are Midwest Region Extension Professionals Prepared To Answer Food Safety Questions About Various Meat Products?, Esther Vanoverbeke, Byron D. Chaves

Nebraska Beef Cattle Reports

Summary with Implications

Forty-eight million consumers in the U.S. get a foodborne illness each year; 128,000 are hospitalized and 3,000 die. Approximately one-third of those illnesses are related to animal-based foods, including meat. With meat-like alternatives being more readily available, it is critical to ensure these foods are handled appropriately to reduce foodborne illnesses. This project evaluated the food safety knowledge of extension professionals related to plant-based products and meat alternatives. A survey was distributed via the North Central Region Extension Center to Extension professionals (N=52). Most respondents, 58%, neither agreed or disagreed that plant-based meats/meat alternatives are microbiologically riskier …

Not Biological, But Built: Structural And Metabolic Pathways Driving Black Maternal Health Disparities In The United States, Alexandra I. Umegboh

CMC Senior Theses

Black infants in the United States are more than twice as likely to die before their first birthday than white infants, a disparity often attributed to genetics, behavior, or individual health choices. However, this idea is challenged by a key contradiction: African immigrant women consistently experience better birth outcomes than U.S.-born Black women despite being similarly racialized. This thesis investigates the origins of this reproductive advantage and the factors contributing to its decline over time. By drawing on epidemiological data, metabolic health research, and literature on African diasporic healing traditions, it argues that the “healthy immigrant effect” is not biological, …

Application Of High-Pressure Processing Lightens The Color Of Cow Tenderloins, Kara A. Reynolds, Leila G. Venzor, Ashley A. Hahn, Grace C. Johnson, Jordan C. Wicks, Mary-Grace C. Danao, Ranjith Ramanathan, Gary A. Sullivan

Nebraska Beef Cattle Reports

Summary with Implications

This study evaluated the impact of high-pressure processing (HPP) on color, oxidative stability, and tenderness of tenderloins (psoas major) from cull cows to determine if HPP could enhance their marketability. Forty cull cow tenderloins were treated at two different HPP pressures and two different holding times, then assessed for instrumental and visual color, lipid oxidation, and Warner-Bratzler shear force during a 7-day stimulated shelf period. HPP increased initial lightness, especially at the highest pressure and longest holding time and improved redness initially. However, redness declined, and discoloration increased over the 7-day period, particularly after processing at higher …

Using High-Pressure Processing To Improve Dark-Cutting Beef Color In Tenderloins, Ashley A. Hahn, Leila G. Venzor, Shelley A. Curry, Grace C. Johnson, Mary-Grace C. Danao, Ranjith Ramanathan, Gary A. Sullivan, Jordan C. Wicks

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a quality defect that negatively impacts consumer appeal and affects the carcass value for both producers and meat processors. These economic losses stem from poor visual appearance and reduced consumer appeal in the retail setting. Notably, different muscles within a carcass exhibit varying degrees of color stability which can influence how dark-cutting manifests across cuts. Therefore, this study aimed to examine the effect of high-pressure processing (HPP) on dark-cutting color-labile muscle. Dark-cutting and normal tenderloins were collected and portioned into two equal sections. Dark-cutting tenderloins were assigned one of 3 treatments: No HPP, 300 …

Defining The Parameters Of High-Pressure Processing To Improve The Quality Of Dark-Cutting Beef, Ashley A. Hahn, Leila G. Venzor, Shelley A. Curry, Grace C. Johnson, Mary-Grace C. Danao, Ranjith Ramanathan, Jordan C. Wicks, Gary A. Sullivan

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a result of preharvest stress and devalues the resulting carcass. High-pressure processing (HPP) has been recently identified as a potential strategy to improve the undesirable appearance of dark-cutting beef. Dark-cutting beef strip loins were collected from a local processing facility, sectioned, and assigned an HPP pressure (300 or 450 MPa) and holding time (0, 1, 30, 60, or 90 s). Overall, HPP increased the lightness and redness of dark-cutting beef, particularly the longer the pressure was held at both pressure levels. Additionally, negative effects such as increased meat discoloration, decreased tenderness, and increased rancidity …

Food Science Faculty Publications and Presentations

This study investigated the optimization and fabrication of soy protein isolate (SPI)-green microalga (MA) 3D-printed films. For optimizing 3D printing, the effects of MA concentration, nozzle size (0.52-0.81 mm), and speed (10-20 mm/s) were examined. The printed films were then dried, and color, mechanical properties, water vapor permeability, structure, and antioxidant activity were analyzed. All the formulations showed shear-thinning behavior and rapid recovery. The concentration of 3 % MA, nozzle size of 0.72 mm, and printing speed of 20 mm/s were selected as the optimized conditions for the best 3D printability. Compared with the control, their elongation at break decreased …

Association Of Serotonin And Ergot Alkaloids On Tissue Partitioning And Contractile Response Of Bovine Blood Vessels, Eriton E. L. Valente, David L. Harmon, John May, Huihua Ji, Ronald J. Trotta, James L. Klotz

Animal and Food Sciences Faculty Publications

Ergot alkaloids can bind serotonin (5-HT) receptors interfering with many physiological functions. However, the mechanism has not been completely established. The objective was to evaluate whether the association of 5-HT and the ergot alkaloid, ergovaline, in a 24-h pre-incubation can affect vascular tissue partitioning and contractile responses. Cross-sections of saphenous veins from five steers were used. In the tissue partitioning experiment, the treatments were the combination of three levels of ergovaline (2.01 × 10⁻⁸ M, 2.01 × 10⁻⁷ M and 2.01 × 10⁻⁶ M) with three levels of 5-HT and a control (5 × 10⁻⁸ M, …

Quantitative Assessment Of Roasted Coffee Freshness Over Time Using Multi-Parameter Analysis, Maya Fetzer

Honors Theses

Roasted coffee undergoes continuous chemical and physical degradation after roasting, yet industry freshness standards remain empirically defined rather than grounded in measurable parameters. This study developed a multi-parameter framework for quantifying roasted coffee freshness by integrating gas-phase and solid-phase analysis, backed by human sensory evaluation, across three roast levels — light (City+), medium (Full City), and dark (Vienna) — over a four-month storage period. CO2 off-gassing was monitored continuously for 30 day, gas chromatography-mass spectrometry (GC-MS) tracked volatile compound changes in headspace gas, and Fourier transform infrared-diffuse reflectance spectroscopy (FTIR-DRIFTS) quantified oxidation-associated functional group changes, and microindentation assessed bean stiffness. …

Manuka Honey Modulates Oxidative Stress In Neuro2-A Cells Through Mitochondrial Regulation, Rachel Abramovici

Honors Undergraduate Theses

Manuka honey is known for its vital usage in wound healing, being an agonist towards fighting infections, and is an acting antioxidant [32]. Its main constituents are flavonoids and phenolic compounds, with methyl syringate (MSYR) being a major active ingredient. The specific compounds responsible for these antioxidant effects, particularly in the CNS, remain unclear. It is hypothesized that pre-treatment of mouse neuroblastoma cells with MSYR followed by hydrogen peroxide exposure will activate the AMPK/SIRT1/PGC-1a pathway, due to MSYR’s phenolic structure, and thus reduce oxidative stress and improve mitochondrial biogenesis. Hydrogen peroxide is a standard reactive oxygen species (ROS) treatment to …

Interaction Of The Gram-Positive Human Pathogen Staphylococcus Aureus With Host Lipids, Sharanya Paul

Theses and Dissertations

Staphylococcus aureus is a prominent pathogen that is known to incorporate straight-chain unsaturated fatty acids (SCUFAs) into its lipids in addition to the normally biosynthesized branched-chain fatty acids (BCFAs) and straight-chain fatty acids (SCFAs). Furthermore, it has recently been shown that the incorporation of oleic acid into S. aureus lipids significantly enhanced the growth of the organism at low temperatures due to the greater fluidity imparted to the membrane. Together with others in the Wilkinson and Dahl laboratory, I have shown that low-temperature growth is enhanced by various SCUFAs, including the human antimicrobial fatty acids sapienic acid, linoleic acid, and …

Assessing Fisheries Dependence Of Coastal Communities In Managed Mangrove Forests In Latin America, Ariel Alexander Quintanilla Magana

Open Access Dissertations

Fisheries dependency refers to the action of a person, community, or society linking their social, cultural, and economic actions to different ecosystem services (ES) for covering their food system with essential marine species, developing a governance system to conserve these fishing areas, their local ecological knowledge, and guaranteeing food security in the coastal areas. In Latin America, most fishing activities are practiced within three nautical miles of the shoreline, estuaries, lagoons, and mangrove forest channels, using small vessels and traditional gear such as hooks, trammel nets, and gill nets. Some coastal communities have developed their subsistence and livelihood activities in …
