The homologous series of 4-mercapto-2-alkanols (C5-C10) was used to investigate the impact of the stereochemistry on the sensory properties of beta-mercapto compounds. In addition, the influence of acetylation was shown by GC/O analyses of the C7-homolog and its acetyl derivatives. Finally, the naturally occurring distributions and concentrations of the stereoisomers of beta-mercaptoheptanols and -heptanones identified in cooked red bell pepper (Capsicum annuum) were determined for the first time.     «
