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 malt alkaloids N-methyltyramine, N,N-dimethyltyramine (hordenine), N-methyl-3-aminomethylindole and N,N-dimethyl-3-aminomethylindole (gramine) are known precursors for N-nitrosamines. Analytical procedures were developed and applied to extract and quantify these alkaloids from malt, green malt, malt roots, and raw barley. A ground malt sample under nitrogen atmosphere was extracted with 5 percent concentrated ammonium...

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:: Amines formed by biosynthesis in germinated barley have been suggested as precursors for N-nitrosodimethylamine (NDMA) in barley malt dried by direct-fired kilning. This hypothesis was verified by germinating raw barley and exposing the resulting malt roots and clean malt to nitrous acid. Quantitation of the NDMA formed indicated that malt...
