Structure and conformation of red radish (Raphanus sativus L.) anthocyanins and their effect on color and pigment stability

Creator:: Giusti Hundskopf, Maria Monica
Abstract:: Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone and chloroform and isolated using C-18 resin. Chemical structure and conformation of major pigments were elucidated by 1-D and 2-D NMR, Mass Spectroscopy, HPLC, and spectral analyses. Two novel di-acylated anthocyanins, pelargonidin 3-0-[2-0-(β-D-glucopyranosyl)-(6-0- trans-p-coumaroyl-...

Effect of whey concentrate crystallization parameters on lactose crystal forms

Creator:: Nonnemacher, Melissa L.
Abstract:: Effects of whey concentrate crystallization parameters of temperature, pH, and length of time of crystallization on lactose crystal forms and amount of lactose crystallized were investigated. Effect of crystallization parameters on freeze-dried powder quality was also investigated. Lactose crystal forms were observed in x-ray crystal diffraction patterns of freeze-dried whey...

Mesurol (methiocarb) residues in grapes and wine and their possible effects on fermentation and wine quality

Creator:: Miller, Frederick Kenton
Abstract:: Wines were made from Pinot Noir and White Riesling grapes which had received field application rates of 2 and 4 lb./acre of the experimental bird repellent Mesurol (methiocarb or 3, 5 dimethyl- 4(methylthio)phenylmethylcarbamate). In addition, Pinot Noir must and press juice and White Riesling press juice were fortified with 15...

Efficacy of electrolyzed oxidizing water and ozonated water for microbialdecontamination of fresh strawberries (Fragaria x ananassa)

Creator:: Udompijitkul, Pathima
Abstract:: The objectives of this project were to evaluate the efficacies of electrolyzed oxidizing (EO) and ozonated waters as antimicrobial agents for enhancing the microbiological safety of fresh strawberries (Fragaria x ananassa). The influence of sodium chloride (NaCl) concentrations used for preparing EO water was evaluated on their bactericidal activities against...

Prevalence and Characterization of Listeria spp. Recovered from Pacific Northwest Produce Handling and Processing Facilities

Creator:: Jorgensen, John
Abstract:: Foodborne illness in the United States continues to be a complex and recurring issue despite our increased understanding of the pathogenic microorganisms responsible. Foodborne illness outbreaks and product recalls linked to pathogenic bacteria have been more frequent in the produce industry (e.g. fruits and vegetables) in the last ten years....

Pineapple juice : phenolic composition and enzymatic browning inhibition

Creator:: Wen, Ling
Abstract:: The phenolic profile of pineapple juice was analyzed by reverse-phase HPLC/Diode Array Detector, and 9 major peaks accounting for 70% of total peak area were characterized. None of these peaks are represented by the pineapple phenolics reported to be present by previous workers. Most of the major peaks are not...

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...

Further Optimization of Controlled Depuration for Eliminating Vibrio parahaemolyticus from Raw Oysters for Safe Consumption

Creator:: Ming, Ziwen
Abstract:: Vibrio parahaemolyticus infections in the United Stated have been linked to consumption of raw shellfish, particularly oysters, with symptoms of headache, abdominal pain, nausea, diarrhea, vomiting. Depuration, as a post-harvest process, has a long history of being applied in shellfish industry to reduce sewage bacteria. In order to reduce the...

Survival of Listeria monocytogenes, Salmonella spp., and Staphylococcus aureus in raw yellowfin tuna during refrigerated and frozen storage

Creator:: Mou, Jing
Abstract:: The consumption of seafood in the United States has increased rapidly in recent years due to high quality protein and health benefits of seafood. Seafood can be a carrier for bacteria normally distributed in the marine environment and, in some cases, can be contaminated by human pathogens. Therefore, there is...

Clostridium perfringens spores : inactivation, germination, and formation

Creator:: Udompijitkul, Pathima
Abstract:: The enterotoxin-producing Clostridium perfringens type A isolates are responsible for the third most common foodborne illness in the United States and can also cause non-foodborne human gastrointestinal (GI) diseases such as antibiotic- associated and sporadic diarrheas. Three important factors contribute to the ability of C. perfringens to cause GI diseases,...
