Adsorptive Surface Modification Of Cellulose Nanocrystals To Stabilize Nutraceuticals Loaded Lipid Carriers For Food Application, Avinash S. Patel

Electronic Theses and Dissertations

Lipid carriers such as emulsions and liposomes have been widely studied as carriers for different nutraceuticals. However, lipid carriers' physicochemical instability results in the leakage of loaded nutraceuticals and the low solubility into the digestion medium, thus reducing the bioaccessibility. Cellulose nanocrystals (CNC) are nano-sized cellulose derivatives obtained after hydrolysis of cellulosic matrices that possess potential applications in functional foods and nutraceuticals. However, hydrophilicity, anionic surface potential, and poor re-dispersibility limit CNC’s applications. The primary objectives of this research were 1) to modify CNC via adsorbing polyethylene glycol (PEG) to stabilize liposomes and to study its physiochemical stability at different …

Effects Of Salt And Garlic Concentration On The Microbial Safety, Biochemical Properties, And Sensory Acceptance Of Spontaneously Fermented Beet Kvass, Abigail Hing

Electronic Theses and Dissertations

Fermentation is the process by which primarily lactic acid bacteria (LAB), an environmentally ubiquitous group of organisms, convert carbohydrates into several byproducts, including acid, ethanol and/or gas. Often these resulting byproducts create desirable foods with unique flavor attributes and an increased inherent safety due to acidification. Vegetables such as red beetroot are suitable commodities for fermentation, due to abundant nutrient sources to sustain the LAB population. However, sufficient growth of LAB may lead to the production of harmful biogenic amines, specifically histamine and tyramine which can cause an allergic reaction and poisoning at high levels. Additionally, red beetroot is grown …

Microbial Diversity Of The Symbiotic Colony Of Bacteria And Yeast (Scoby) And Its Impact On The Organoleptic Properties Of Kombucha, Danielle L. St-Pierre

Electronic Theses and Dissertations

Kombucha is an effervescent fermented tea beverage that is gaining popularity for its probiotic nature and purported health benefits. The market for kombucha is expected to reach $1.8 billion by the year 2020. The composition of microbes that compose the symbiotic colony of bacteria and yeast (SCOBY) is highly variable with some species commonly found from the Gluconobacter, Acetobacter, Zygosaccharomyces, Saccharomyces, and Schizosaccharomyces genera.

It was hypothesized that different SCOBYs, obtained from different sources would vary in microbial diversity and produce different biochemical and flavor profiles in the resulting beverage over several generations. Kombucha is a fermented …

Attenuating The Antibody Reactivity Of The Shrimp Major Allergen (Tropomyosin) Using Food Processing Methods, Adeseye Lasekan

Electronic Theses and Dissertations

Shrimp is one of the major causes of adverse allergic reactions in both adults and children. Consumers with shrimp allergy have an immune system that is hypersensitive towards certain proteins in shrimp. The immune system of these consumers produces an antibody, immunoglobulin E (IgE), which binds to specific regions on these proteins and activates reactions leading to adverse symptoms. Most shrimp allergic consumers have IgE that binds to a shrimp myofibrillar protein known as tropomyosin. Other than avoidance of shrimp, structural modification of shrimp tropomyosin using food processing methods could influence the capacity of this allergenic protein to bind IgE. …

A Competitive Assessment Of Commercial Elderberry (Sambucus Sp.) Products And The Evaluation Of Copigmentation Within Elderberry Tinctures, Joseph A. Galetti Phd

Electronic Theses and Dissertations

Elderberry (Sambucus sp.) fruit is a healthful food with a variety of reported curative properties and is among the richest sources of anthocyanic pigmentation, which are the primary factors for its commercial use. Although a variety of value-added elderberry products are available to consumers, it is questionable as to which product form contains the highest nutrient levels and color stability characteristics, and represents the best value to consumers. It was the objectives of this research to evaluate a variety of commercial elderberry products, and to develop a value-added elderberry product with enhanced nutrient and color stability.

The first part …

Cultural Diabetes, Keri E. Noll

Electronic Theses and Dissertations

Diabetes has become a cultural problem across America, but particularly in the Midwest and Southern regions. For my film, I explored these two areas and compared the food and exercise culture to one of the healthier regions, the West. Having moved from Indiana to Colorado, I used my own personal experiences to analyze why people in the Midwest struggle with diabetes and obesity at such a higher rate than those nearer to the Pacific Ocean. Through a series of interviews with close friends and observational analysis of each state, I came to learn something very important about health: our food …
