中文摘要: 采用顶空-固相微萃取对咂酒中挥发性成分进行提取,通过气相色谱-质谱联用技术对提取出的挥发性成分进 行定性和定量分析。结果表明:从咂酒中共鉴定出挥发性成分 50 种,其中酯类和醇类是咂酒中种类和含量最多的两种 挥发性物质,分别为 20 种和 15 种。咂酒中的主要挥发性化合物有异戊醇(19.48 %)、乙酸乙酯(17.78 %)、丁二酸二乙酯(14.73 %)、辛酸乙酯(10.95 %)、乙酸戊酯(9.51 %)、癸酸乙酯(5.92 %)、异丁酸(5.91 %)、己酸乙酯(3.07 %)。
Abstract:The volatile components of Za wine were extracted by using headspace-solid phase microextraction, and gas chromatography-mass spectrometry identified the volatile components and analyzed their content. The results showed that 50 volatile compounds were identified from Za wine. The esters and alcohols were the- mostabundant category and highest contenttwo kinds of volatile substances, which were 20 and 15 respectively. The main volatile compounds were isoamyl alcohol(19.48 %), ethyl acetate(17.78 %), butanedioic acid, di- ethyl ester(14.73 %), octanoic acid, ethyl ester(10.95 %), acetic acid, pentyl ester(10.95 %),ethylcaprate (5.92 %), isobutyric acid(5.91 %), ethyl caproate(3.07 %).
