摘要
采用浸入式固相微萃取和液-液萃取两种前处理方法,结合气相色谱-质谱联用技术对扳倒井芝麻香型白酒中含硫组分进行分析。经标样核对确定,共鉴定出4种含硫化合物,包括3-甲硫基丙醇、3-甲硫基丙酸乙酯、二甲基三硫和甲硫基乙酸乙酯,其中甲硫基乙酸乙酯为首次发现。本研究为深入探讨芝麻香型白酒的特征风味组成奠定了基础。
The sulfur compounds in Bandaojing sesame flavor liquor were identified by using DI-SPME and liquid-liquid extraction followed by GC-MS.Four kinds of sulfur compounds were characterized.Addition to 3-Methylthiopropanol which is national standard specified content,Ehtyl 3-methylthiopropionate,Methyl trisulfide and Ethyl（methylthio） acetate were also determined.And Ethyl（methylthio） acetate was first discovered.The experiment results lay a foundation for further study of sesame flavor liquor.
