[9,10-methylene-¹⁴C] sterculic acid metabolism in the rat : urinary metabolites, liver tissue distribution, and induced [omega]-hydroxylase activity

Creator:: Eisele, Thomas Anthony
Abstract:: Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1% of the label was expired as carbon dioxide. The majority of the label was excreted in the urine as short-chain dicarboxylic acids with an intact cyclopropane ring. The major metabolites for...

A comparison of porous polymers used in collecting organic volatiles in foods

Creator:: Boyko, Alayne Linda
Abstract:: Porapak Q, Chromosorb 102, and Tenax GC, three porous polymers commonly used as adsorbents in headspace analyses were investigated. The retention times of various low-boiling compounds relative to water were measured on the collection columns to determine which compounds would be lost during the water removal step employed after sampling...

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...

Acid stabilization of autolyzed fish : storage and nutritional characteristics

Creator:: Culbertson, Jeffry Dean
Abstract:: The effects of ambient temperature storage on the chemical and nutritional characteristics of phosphoric and sorbic acid-stabilized fish autolysates were determined. Variations in sample composition due to autolysis, deboning, and acidification were also evaluated. Autolysates of English sole (Parophrys vetulus), true cod (Gadus macrocephalus), Dover sole (Microstomus pacificus), and orange...

Acute toxicity and carcinogenic activity of ochratoxin in rainbow trout (Salmo gairdneri)

Creator:: Doster, Robert Charles
Resource Type:: Masters Thesis

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...

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...

Alterations in growth, lipid metabolism and P:O ratios in mice fed Sterculia foetida oil

Creator:: Lehman, Michael Wesley
Abstract:: Cyclopropenoid fatty acids (CPFA) are natural components of cottonseed oil, a major food oil in the United States. The ability of CPFA to cause abnormal biochemical and physiological effects when fed to laboratory and farm animals has prompted an investigation of their effects on mice. Between 0.05 and 0.55% CPFA...

Analysis of N-nitrosamines and nitramines in foods and herbicides

Creator:: Hotchkiss, Joseph H.
Resource Type:: Dissertation

Anthocyanin degradation in freeze-dried strawberries and strawberry puree

Creator:: Erlandson, John Arthur
Abstract:: Anthocyanin degradation in freeze-dried strawberry puree was studied under various relative humidity conditions at 37°C. Moisture was found to be the determining factor in the rate of pigment degradation. Storage at relative humidities below 11% provided good pigment retention in this low-moisture product. Enzymatic degradation of the anthocyanin pigment did...
