Determination of Seven Volatile Components in Xiangxi Aromatic Vinegar by GC-MS
The Xiangxi aromatic vinegar were pretreatmented by SDE,and the content of ethyl acetate,ethanol,ethyl lactate,2,3-butanedione,3-hydroxyl-2-butanone,furfural and 2,3-butanediol was determi-nated by GC-MS.HP-INNOWAX capillary gas chromatographic column and GC-MS-HS were used.The sample inlet temperature was 220 ℃,the split ratio was 40∶1,the fourth stage rod temperature was 230℃,the ion source temperature was 230 ℃,and SIM mode was used.The results showed that linear rela-tionship was between 0.991 and 0.999,and the method repeatability was less than 10％,which indicates that this method can be used for the determination of volatile components in Xiangxi aromatic vinegar.
