Descriptive analysis of Pinot noir juice and wine qualities

Creator:: Ludwig-Williams, Nancy
Abstract:: The overall purpose of this study was to develop sensory evaluation methodology whereby wine quality can be predicted from juice quality. Descriptive analysis was used by a trained panel to describe Pinot noir juice and wine from three sources. From each source, one wine and four juice samples (a control...

Financial recordkeeping practices of self-employed dietetic practitioners

Creator:: Cox, Nancy R.
Abstract:: The practice of dietetics has changed over the past several years to include an increasing number of dietitians working in private practice. The 1986 census of The American Dietetic Association identified 2,383 (4.3%) of the membership as active in the Consulting Nutritionist in Private Practice group. Private practice opportunities have...

Initial velocity analyses of milling effects on rates of enzyme-catalyzed saccharification of native wheat straw

Creator:: Nguyen, Quynh M.
Abstract:: There is considerable interest in developing environmentally friendly processes for the economical conversion of biomass plant material to biofuels, bioproducts and biomaterials. One approach to such a conversion process is to make use of enzymes for the conversion of plant polysaccharides to simple sugars; the simple sugars could then be...

Textural and electrical properties of Pacific whiting surimi under ohmic heating

Creator:: Yongsawatdigul, Jirawat
Abstract:: Feasibility of ohmic heating to overcome gel-weakening in Pacific whiting surimi was investigated. An ohmic heating apparatus was developed using two rhodium-coated stainless steel electrodes inside a polyvinyl chloride (PVC) tube, a variable transformer, and voltage and current transducers. Rapid heating associated with the ohmic process quickly inactivated endogenous proteinase(s),...

Characteristics of Northern squawfish (Ptychocheilus oregonensis) and feasibility for utilization as human food

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

Characterization of Vibrio parahaemolyticus isolated from Oregon and Washington coastal water and development of improved methods for Vibrio parahaemolyticus detection

Creator:: Duan, Jingyun
Abstract:: Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....

The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

Creator:: Valsta, Liisa M.
Abstract:: In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

Characterization of Pacific whiting protease and food-grade inhibitors for surimi production

Creator:: Weerasinghe, Vasana C.
Abstract:: Cathepsin B was the most active cysteine proteinase in the Pacific whiting (Merluccius productus) fish fillet, and cathepsin L in surimi when the activities of the most active cysteine proteinases (cathepsin L, B, and H) were compared. Cathepsin L showed maximum activity at 55°C in both fish fillet and surimi,...

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...

Identification of bacteria crucial to histamine formation and monitoring their occurrence and histamine accumulation in scombroid fish

Creator:: Kim, Shin-Hee
Abstract:: Bacterial histamine formation in mackerel and albacore was studied by inducing histamine in the muscles under controlled storage conditions. The optimum temperature for histamine formation was 25°C. The highest level of histamine detected was 283 mg/100 g in the 2-day stored mackerel; and 67.1 mg/100 g in the 6-day stored...
