Determination of Volatile Metabolites in Vinegar by Solid-Phase Microextraction–Gas Chromatography–Mass Spectrometry (SPME–GC–MS)

AbstractSolid-phase microextraction (SPME) is an easy, sensitive, and environmentally friendly technique that has been employed, coupled to gas chromatography or liquid chromatography, to determine a huge amount of analytes with different volatilities. The present work describes the procedure to follow in order to determine volatile compounds in vinegar by SPME–GC–MS.Key wordsSPMEVinegarVolatile compoundsGas chromatographyMass spectrometryExtraction
