Antioxidative Activity of Thiazoiidine and 1,3-Ditiiiolane. Saturated cyclic sulfides represent another common class of sulfur-containing heterocyclic compounds formed in model systems and cooked foods. We have selected thiazoiidine and 1,3-dithiolane as model compounds for which to evaluate the antioxidative activity of this class of compounds and the results are shown in Figure 6. 1,3-Dithiolane appears to exhibit slightly higher activity than that of thiazoiidine. Both, however, inhibit heptanal oxidation for a longer period than do the thiophene derivatives presumably due to their different structural characteristics and hence potentially different mechanisms of antioxidative action.
