Gas chromatography/olfactometry and descriptive analysis of cold-pressed lemon oil aroma

Creator:: Young, Sheri L.
Abstract:: Lemon oil quality is affected by numerous factors including lemon variety, climate, soil type, extraction method, etc.. Therefore, quality largely depends upon the lemons' origin, and aroma profiles of oils obtained throughout the world have potential to vary considerably. This research was conducted to identify differences in the aroma profiles...

Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

Creator:: Smith, John B.
Abstract:: Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...

Microbial characterization of cassava (Manihot esculenta Crantz) fermentation

Creator:: Ngaba-Mbiakop, Pierre Rolland
Abstract:: Micro-organisms associated with gari, produced in Cameroun, Africa, by the traditional method and that produced in the laboratory, were isolated, identified, and screened for their abilities to produce gari flavor. Gari production, under the controlled conditions was attempted utilizing these isolates and the dairy starter cultures. Some of the volatiles...

Drug resistance, source, and environmental factors that influence fecal coliform levels of Tillamook Bay

Creator:: Kelch, William James
Abstract:: In order to determine the source of bacteria in Tillamook Bay, Oregon, water samples were collected monthly for six months during the rainy season from October 1975 through March 1976 from the bay and its tributaries, the Kilchis, Trask, Tillamook, and Wilson Rivers. Fecal coliform levels of these samples were...

Alteration of certain physiological and biochemical parameters in livers of rainbow trout fed methyl sterculate

Creator:: Struthers, Barbara Oft
Abstract:: The cyclopropene fatty acids, sterculic and malvalic, occur naturally in a major food lipid, cottonseed oil, and have been implicated in several physiological disorders. Rainbow trout in this study were fed semipurified diets containing 200 or 300 ppm methyl sterculate, and the effects on hepatic lipid and glycogen levels, lipid...

Dimethyl disulfide produced in sterile fish muscle by Pseudomonas putrefaciens

Creator:: Rhee, Kie Ho
Abstract:: Sterile fish muscle homogenate was prepared from the individually line caught black rockfish (Sebastes melanops) and inoculated with the pure culture of Pseudomonas putrefaciens strain 17. The inoculated homogenate was incubated at 5°C and the growth and production of volatile sulfur compounds determined by a combined gas-liquid chromatography and mass...

Aflatoxin B₁ metabolism by rainbow trout (Salmo gairdneri)

Creator:: Schoenhard, Grant Louis
Abstract:: Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy confirmed the microsomal...
