Egg White Hydrolysate In Hypertension: A Mechanistic Investigation Of Gut Microbiota Dependent And Independent Pathways, Emerson David Nolasco

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …

Cazyme Gene Cluster Diversity In Human Gut Microbiome, Yi Xing

Department of Food Science and Technology: Dissertations, Theses, and Student Research

In gut microbiome research, carbohydrate-active enzyme gene clusters (CGCs) have emerged as key functional units for understanding microbial glycan degradation. Unlike taxonomic or broad pathway annotations, CGCs offer gene-cluster-level resolution and capture substrate-specific microbial functions. However, their diversity and distribution in relation to host metabolic phenotypes, such as obesity, remain poorly characterized. This study tests the hypothesis that the composition and abundance of fiber-targeting CGCs vary between obese and healthy human gut microbiomes, reflecting distinct microbial carbohydrate utilization strategies. To examine this, we constructed a high-quality reference CGC dataset comprising 94,019 clusters from the Unified Human Gastrointestinal Genome and profiled …

Digesting The Details: How Cooking Shapes The Microbiome And Influences Obesity, Tracy Lieu

University Honors Theses

Obesity is a growing global health concern linked to chronic diseases and changes in the gut microbiome. While diet is known to affect gut microbes, less attention has been given to how food processing methods, such as heating, fermentation, and cold processing, change food in ways that influence the gut microbiome and health. This thesis reviews research on how different cooking and preparation techniques affect the availability of nutrients for microbial fermentation and the resulting effects on microbial diversity and metabolism. The findings show that fermentation and cold processing are the most supportive of gut health. These methods help preserve …

Influence Of Physical Properties Of Fat On Product Quality, Shelf-Life And Consumer Acceptance Of Chocolate-Coated Products, Audrey Lidgard

All Graduate Theses and Dissertations, Fall 2023 to Present

In chocolate-coated products, oil migration in fats can lead to chocolate softening, filling hardening, discoloration, and lower consumer acceptance. This study examined three different fats (soy- palm-, and palm-kernel (PK) based), crystallized under different conditions (cooling rate and use of high intensity ultrasound (HIU)) to examine how the crystallization conditions impact the physical properties of confectionery products. These conditions produced fats with high and low oil binding capacities (OBCs); the ability of crystal networks to entrap liquid oil. Model systems were created to examine measurable quality degradation and consumer acceptance of chocolates placed in contact with the fats; one with …

Understanding The Impact Of Colloidal Calcium Phosphate On The Ph Variation In Cheddar Cheese During Early Stages Of Aging, Rachel Lindstrom

All Graduate Theses and Dissertations, Fall 2023 to Present

The Cheddar cheese industry has recently observed variation in the pH of their cheese during the early stage of storage. This variation may be due to the addition of the faster acid producing thermophilic starter culture Streptococcus thermophilus which was recently introduced into the Cheddar cheese making process. This starter culture may impact the calcium buffering properties of the cheese due to more retention of the insoluble calcium (INSOL Ca) within the cheese. To investigate this problem, we studied how insoluble calcium affects cheeses with pH ranging from 4.8 to 6.6 and found that INSOL Ca was positively correlated with …

Food Safety, Livestock Health, And Productivity Of A Layer Farm Following Implementation Of A Certified Haccp System In Japan, Hiroshi Akaike, Makoto Nagai, Tomomitsu Alexandre Okatani, Sumalee Boonmar, Yukio Morita

The Thai Journal of Veterinary Medicine

This study examined the safety and productivity of a layer farm over a 3-year period following the implementation of a farm Hazard Analysis and Critical Control Points (HACCP) system in 2019. The critical control point was “automatic egg collection” and no deviations from critical limits were observed, indicating the eggs were safe. In addition, the egg production rate increased and the feed conversion rate decreased. In contrast, the viability after the introduction of a farm HACCP system, in which the replenishment of new hens was discontinued after forced molting, showed an increasing trend. These results suggest that the HACCP system …

Extraction Method Effects On Structural Properties And Functional Characteristics Of Dietary Fiber Extracted From Ginseng Residue, Xiaoyu Feng, Kashif Ameer, Karna Ramachandraiah, Guihun Jiang

School of Medicine Faculty Publications

In this research, the dietary fibers (DFs) from ginseng residue were extracted by employing three different extraction methods (alkaline: AL, acidic: AC, enzymatic: EN). The extracted DFs were characterized in terms of their structural and functional properties. The results clearly showed that, regardless of the extraction methods, all DF samples exhibited representative infrared spectral features. The DF extracted by AC (citric acid) had more porous structures with a looser configuration, in conjunction with high apparent viscosity, whereas the DF extracted by EN (α-amylase and protease) exhibited higher thermal stability. Moreover, the monosaccharide composition of the DF samples was significantly influenced …
