Abstract:Volatile compounds of traditional Dushan greengrocery fermented were investigated jointly by steam distillation,gas chromatographymass spectrometry(GC/MS).The results showed that a total of 11 classes,28 species volatile components were identified from 2 different samples of traditional Dushan greengrocery fermented.These volatile components included ester,acid,amide,ethanol,aldehyde,hydroxybenzene,alkene,benzene,ketone,thiazole and salt.Among them,acid,aldehyde and ester were the main volatile components,which played an important role in flavor formation of Dushan greengrocery fermented.
