Determination of Volatile Metabolites in Vinegar by Stir Bar Sorptive Extraction–Gas Chromatography–Mass Spectrometry (SBSE–GC–MS)

Abstract

Stir bar sorptive extraction (SBSE) is a rapid, sensitive, precise, and environmentally friendly extraction technique that, coupled to gas chromatography–mass spectrometry detection (GC–MS), enables the simple determination of volatile organic compounds in liquid samples. The present protocol describes the procedure for the determination of volatile compounds in vinegar by means of SBSE–GC–MS.
