摘要/Abstract

摘要：采用蒸馏萃取法对湘西香醋的挥发性物质进行提取处理，利用气质联用仪测定了其中乙酸乙酯、乙醇、乳酸乙酯、2,3-丁二酮、3-羟基-2-丁酮、糠醛和2,3-丁二醇含量.分析测试条件为HP-INNOWAX毛细管气相色谱柱，进样口温度220 ℃，分流比40∶1，四级杆温度230 ℃，离子源温度230 ℃，SIM模式.结果表明，气质联用法测定湘西香醋中乙酸乙酯、乙醇、乳酸乙酯、2,3-丁二酮、3-羟基-2-丁酮、糠醛和2,3-丁二醇的线性关系系数在0.991~0.999之间，方法重复性小于10%，均满足测定需求，可用于湘西香醋中挥发性成分的定量测定.

Abstract: 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 determinated 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 relationship 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.

Key words: Xiangxi aromatic vinegar, GC-MS, volatile components, SDE
