Abstract:: The reactions between sodium nitrite and the polyamines spermidine and spermine were investigated. When reacted at 80°C for 1 hr at pH 3.5 with a 1:3 molar ratio of amine groups to sodium nitrite, five volatile nitrosamines were identified as products in the nitrosation of spermidine. 3HC1, and two volatile...

Abstract:: The purpose of this study was to characterize the nonvolatile, water soluble, bis(hydroxyalkyl)N-nitrosamines produced from the reaction of spermidine and nitrite. The biologically occurring polyamine spermidine was reacted with nitrite in the presence of acid. The reaction products were isolated and converted to trimethylsilyl (TMS) derivatives. The derivatized products were...

Abstract:: A dose related carcinogenic response was established for dimethylnitrosamine administered in the diet of rainbow trout (Salmo gairdneri). An equation was derived for the relationship between dose and hepatocellular carcinoma incidence. From a published dose response study using Porton rats as a test animal, a second equation was derived for...

Abstract:: The formation of 3-hydroxy-N-nitrosopyrrolidine from decarboxylation of 4-hydroxy-N-nitrosoproline was demonstrated in model heating system designed to simulate the conditions of frying bacon. The identification of the nitrosamine was achieved by comparison of its TLC R [subscript f] value, gas chromatographic retention time, and mass spectral fragmentation pattern with those of...

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...

Abstract:: 2, 4-Decadienal was autoxidized by subjecting a purified sample to an atmosphere of pure oxygen for 14 hours. A qualitative analysis of the autoxidative degradation products was made utilizing tandem gas chromatography and mass spectrometry. Additional information was obtained from the determination of the melting point of the DNP-hydrazone derivative...

Abstract:: A rapid gas liquid chromatographic method was adapted to processed Dungeness crab for the determination of basic and neutral volatiles. Methylamine, dimethylamine, and trimethylamine were measured in processed Dungeness crab for the first time. Generally, the range for trimethylamine was 42 ppm for frozen crab to 700 ppm for iced...
