The thermal degradation of both cysteine and glutathione was studied in a closed model system. Aqueous solutions of each reactant were adjusted to pH 7.5 and heated at 180 °C, representing frying temperature. From the degradation of cysteine, 34 volatile compounds were identified and the major products were 2, 4, 6-trimethylperhydro-1, 3, 5-thiadiazine and 2, 4, 6-trimethylperhydro-1, 3, 5-dithiazine. Of the 17 compounds identified as products of glutathione degradation, the isomers of 3, 5-dimethyl-1, 2, 4-trithiolane were the major products.
