The effect of wine matrix on the analysis of volatile sulfur compounds by solid-phase microextraction-GC-PFPD

Creator:: Davis, Peter M.
Abstract:: Constituents of the wine matrix, including ethanol, affect adsorption of sulfur volatiles on solid-phase microextraction (SPME) fibers, which can impact sensitivity and accuracy of volatile sulfur analysis in wine. Several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl...

Effect of temperature cycling on the production of aflatoxin by Aspergillus flavus

Creator:: Stutz, Howard Kent
Abstract:: The effect of cycling temperatures on production of aflatoxin by Aspergillus flavus (V3734-10) when grown upon various substrates was studied. The parameters of temperature and time were selected to simulate environmental conditions in Oregon during harvest of filberts and walnuts. The heat input required for aflatoxin synthesis in terms of...

The growth of Salmonella typhimurium, Staphylococcus aureus, and Bacillus cereus in bakery products as related to the food distribution system

Creator:: Guy, Vicki H.
Abstract:: Current retail food distribution practices, microbial quality of bakery products, and the potential for growth of food borne pathogens (Staphylococcus aureus, Salmonella typhimurium, and Bacillus cereus) were examined using pumpkin pie as a model. The pumpkin pies, as obtained from the retail outlets, showed contamination with food pathogens. The aerobic...

Immunological and physiochemical characterization of fish myosins

Creator:: Reed, Zachary H.
Abstract:: Increased sales of surimi seafood, with the majority as crabstick in the United States indicates that surimi based products are becoming more popular. With growing popularity, there is increased competition for market share. Under these circumstances, some companies may be willing to sacrifice product quality in order to facilitate manufacture...

The influence of dietary fatty acids on tissue lipid composition in rainbow trout (Salmo gairdneri)

Creator:: Greene, Diana H.
Abstract:: The effects of different dietary lipids on the growth, nutrition and tissue lipid profiles of rainbow trout raised to market size on a commercially available ration were examined. Rainbow trout of 80 g mean initial weight were fed pellets prepared according to Oregon Moist Pellet specifications for 20 weeks. Salmon...

A filter paper assay for low cellulase activities and the cultivation of Trichoderma reesei on acid whey and sweet whey permeate

Creator:: Nordmark, Tor Soren
Abstract:: The traditional filter paper assay for saccharifying cellulase originally described by M. Mandels et al (1976) has been modified to make possible low activity determinations of Trichoderma cellulases. The enzymatic activity appears to decline during a prolonged incubation period if no precautions have been taken. By means of adding bovine...

The effect of prerigor electrical stimulation of beef muscle on selected bacteria

Creator:: Nygaard, Michael DuWayne
Abstract:: This investigation was designed to study the possible effects of the electrical stimulation of beef muscle on microorganisms present on the meat surface during and after treatment. The effect of electric current on microorganisms in minimal media suspension was also studied. Cell viability before and after electrical treatment or exposure...

Apparent inhibition of Pacific whiting surimi-associated protease by whey protein concentrate

Creator:: Piyachomkwan, Kuakoon
Abstract:: Surimi is a seafood product which is used to manufacture restructured products such as artificial crab and lobster. Surimi is produced from fish fillets by washing to remove sarcoplasmic proteins and increase the concentration of myofibrillar proteins, and mixing with cryoprotectants. A valuable attribute of surimi is its ability to...
