In the present application are disclosed a method for enhancing or improving the flavor of foods or drinks in general with the use of a non-volatile thiazolidine compound alone or a non-volatile flavor compound and/or a reaction flavor concurrently with the non-volatile thiazolidine compound, a simple and effective method for improving the flavor of a retort food by suppressing the flavor-deterioration upon heat sterilization or the unpleasant odor at the time of eating, and a simple and effective method for improving the flavor of a soybean-incorporated food product by suppressing the unpleasant, weed-like odor peculiar to soybean.

The protonation and zinc-ion co-ordination equilibria of 2-(polyhydroxyalkyl)thiazolidine-4-carboxylic acid derivatives have been studied by potentiometric titration in the range pH 1.5-8.In most cases the formation of complexes with a metal-to-ligand ratio of 1:2 was demonstrated, but at above pH 6 mixed-ligand complexes involving hydroxide-ion co-ordination were also observed.The protonation and complex-formation constants were shown to depend on the structure of the polyhydroxy chains.In the case of the protonation constants this is due to the rearrangement of the intramolecular hydrogen-bonding network, while the complex-formation constants depend on the conformation of the OH groups on the first carbon atoms of the polyol chains.

The diastereomeric 4-thiazolidinecarboxylic acids 3 and 4, obtained by condensation of DL-cysteine (DL-1) with D-(+)-galactose (2), can be separated by crystallization.Ring cleavage of 3 or 4 gives L-cysteine (L-1) or D-cysteine (D-1), respectively.Instead of D-(+)-galactose other chiral aldoses can be employed as resolution agents.
