抄録

The stability of sorbic acid to light and the interaction of sorbic acid with sulfur-containing amino acids were studied. It was found that the trans-trans form of sorbic acid was markedly isomerized by ultraviolet irradiation. The stability of sorbic acid fell markedly and the formation of TBA-active substances increased remarkably in the presence of cysteine and cystine under all conditions of irradiation with ultraviolet and fluorescent light, and even on standing in the dark. These reactions were inhibited by ascorbic acid, propyl gallate and dibutyl hydroxy toluene, but were stimulated by ferric salts and histidine. The main reaction product was identified as 5-(S-cysteinyl)-3-hexanoic acid, which was formed from sorbic acid and cysteine under all the conditions tested.
