Abstract/Summary

2-Methyl-3-furanthiol (MFT) and its derivatives were identified for the first time in heated model systems containing ascorbic acid and cysteine. More MFT was formed with ascorbic acid compared to the analogous system containing ribose. It is suggested that in the ribose/cysteine system, much of the cysteine was bound up in a semi-stable thiazolidine, thus limiting the formation of H2S and the subsequent conversion of norfuraneol to MFT.
