Analysis of DMTS in Alcoholic Drinks Using SPME Arrow

Introduction

Dimethyl trisulfide (DMTS) is known as an off-flavor compound in aged alcoholic drinks. This is due to an oxidation degradation which is caused by enzymes in the liquor. Thus, the ability to control the quality of alcoholic drinks by measuring DMTS has been attracting growing attention. Additionally, many uses of solid phase micro extraction (SPME) to concentrate DMTS have been reported. This report introduces the analysis of DMTS by the vapor phase extraction method and soaking extraction using SPME Arrow, which was shown to be more effective for concentration than the conventional SPME method.
