Nutritional and biochemical characterization of Moraxella species isolated from fishery sources

Creator:: Vernon, Stephen M.
Abstract:: One hundred and fourteen strains of Moraxella species isolated from marine fishery sources were investigated to determine the cause of this organism's predominance in seafood. The nutritional requirements, effect of pH, NaCl concentration, and temperature on growth, utilization of carbohydrates, protein, and lipid, resistance to 12 antibiotics, sensitivity to phenethyl...

The Influence of Vineyard and Winery Nitrogen Supplementation on Chardonnay and Pinot Noir Winemaking and Wine Quality

Creator:: Ruppel, Meghan L.
Abstract:: Nitrogen is a crucial nutrient required by yeast to successfully complete alcoholic fermentation. In particular, the concentration of yeast assimilable nitrogen (YAN) influences fermentation kinetics and the production of a range of volatile aroma compounds, both desirable and undesirable. YAN is naturally present in the grape, but producers can boost...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

Characterization and detection of potential adulterants in apple juice by pattern recognition methods

Creator:: Pilando, Leticia S.
Abstract:: Fruit juice concentrates- hard pear, soft pear, fig, prune, raisin, white grape, and pineapple, and sweeteners-invert beet, invert cane, and high fructose corn syrup (HFCS) were characterized by sugar profiles, nonvolatile acid profiles, UV spectral profiles, and mineral content. These fruit juices and sweeteners were also used to adulterate commercial...

The production of surimi from Pacific whiting (Merluccius productus) and evaluation of kamaboko gels

Creator:: Chang-Lee, Maria Virginia
Abstract:: Yield, proximate composition, and proteolytic activity were determined in each unit operation during production of surimi from Pacific whiting. Preliminary studies involved the addition of protein adjuncts such as egg white (EW), whey protein concentrate (WPC), and soy protein isolate (SPI), at different levels, to kamaboko gels in order to...

Accumulation of dietary polychlorinated biphenyl by rainbow trout (Salmo gairdneri)

Creator:: Lieb, Andrew James
Abstract:: This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...

Application of probiotics and green tea extract in post-harvest processes of Pacific oysters (Crassostrea gigas) for reducing Vibrio parahaemolyticus and extending shelf life

Creator:: Xi, Dunyu
Abstract:: Vibrio parahaemolyticus is a human pathogen which is prevalent in marine environment. Consumption of raw or undercooked seafood contaminated with V. parahaemolyticus can cause foodborne illness. This study investigated the application of probiotics in depuration for reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas) and the utilization of green...

Factors affecting the antimicrobial activity of vitamin K₅

Creator:: Merrifield, Larry Stanford
Abstract:: Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a water soluble analog of vitamin K has been shown to possess an antimicrobial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preservative, and it was the purpose of this study to...

Rapid assay for Bacillus proteinases in raw milk as detected by a simple casein denaturation method

Creator:: Feijoo, Sergio C.
Abstract:: A casein agar diffusion method was developed to detect and quantify pertinent levels of proteinases produced in raw milk supplies by heat resistant Bacillus sporeformers. In order to optimize the required heat treatment conditions of raw milk samples, trials that involved a combination of different temperatures and times were evaluated....

Analytical approach to the quantitative analysis of silicon in plants : its application to plant silica extraction

Creator:: Boone, Carmen E.
Abstract:: The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...
