The potential role of aliphatic gamma- and delta-lactones in beer fruit aroma

Creator:: Hotchko, Rachel Ann
Abstract:: This work set out to examine the potential contribution of five aliphatic lactones, γ-nonalactone, γ-decalactone, γ-dodecalactone, δ-decalactone and δ-dodecalactone to stone fruit aroma in beer. This work consists of three related studies; lactone olfaction thresholds, additive/synergistic aroma effects and a gas-chromatography-mass-spectrophometry method of analysis. First was the determination of these...

Studies in cereal science : arabinoxylans, glutenins, and their interactions; determining optimum water addition in noodle doughs; and quality and nutritional traits in a hard x soft wheat cross

Creator:: Kongraksawech, Teepakorn
Abstract:: The major components of wheat flour are keys to its functionality in processing and product quality. The major components, other than the lipids, are polymers: starch, protein, and non-starchy polysaccharides (NSP). In wheat NSP are primarily arabinoxylans (AX). These components are compartmentalized in the grain but are forced into close...

Science and efficacy of mild sodium hydroxide treatments in enzyme-based wheat straw-to-glucose processing

Creator:: Sophonputtanaphoca, Supaporn
Abstract:: The work described in this dissertation focused on chemistry related to the use of aqueous sodium hydroxide as a treatment in the processing of wheat straw. A major emphasis was the comprehensive evaluation of straw component partitioning due to sodium hydroxide (NaOH) processing. This was evaluated over a range of...

Factors that Influence the Sensory Characteristics of Dry-hopped Beer

Creator:: Vollmer, Daniel M.
Abstract:: When hops are added to beer, varying degrees of hoppy aroma persist in the finished beer as a result of a number of factors. Dry-hopping is a technique whereby hops are added to beer post-fermentation to leverage the maximum aroma potential of the hop essential oils while minimizing bitterness contribution...

Investigating the Quality Dynamics of American Aroma Hops Intended for Dry-Hopping Beer

Creator:: Lafontaine, Scott R.
Abstract:: Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...

Biological preparation of ¹⁴C labeled aflatoxin

Creator:: Schoenhard, Grant Louis
Abstract:: Selected parameters that affect crude toxin production in both primary culture (growing cell culture) and resting culture were examined during efforts to produce sufficient crude toxin for purification. The parameters included carbohydrate and label source and concentration, cell concentration, incubation time and temperature and shaker speed. A higher yield of...

Effect of lactic acid bacteria growth on Brettanomyces bruxellensis growth and production of ethylphenols

Creator:: Chescheir, Stuart C.
Abstract:: The yeast Brettanomyces bruxellensis is the most important wines spoilage yeast encountered during winemaking as it can survive in wine for long periods, requires minimal nutrients for growth, and can be difficult to control. Brettanomyces produces two major spoilage products, the volatile phenols 4-ethylphenol (Band-Aid, medicinal smell) and 4-ethylguaiacol (smoke,...

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...

Flavor development of cheddar cheese under different manufacturing practices

Creator:: Lemus, Freddy Mauricio
Abstract:: Cheddar Cheese samples (good cheese, weak cheese, cheese made with pasteurized milk, cheese made with heat-shocked milk, cheese from production plant A, cheese from production plant B, cheese made with adjunct culture, and cheese made without adjunct culture), were evaluated during the ripening stage. Proteolysis was studied by a fractionation...

Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...
