摘要: 采用固相微萃取法(SPME),结合气相色谱-质谱(GC-MS)技术手段对产自甘肃景泰条山农场的兰州“大接杏”杏汁及其发酵汁的挥发性物质进行了检测分析。分别检索定性出杏汁挥发性物质组分57种,发酵饮料挥发性物质组分50种。经分析比较:杏汁经发酵后损失的挥发性风味物质共42种,其中减少最多的是烃类化合物;新增的挥发性风味物质共35种,其中增加最多的是酯类和醇类化合物;发酵后挥发性风味物质相对含量明显减少的有乙酸己酯、异松油烯、松油醇、十四烷、十二烷,相对含量明显增加的有乙醇、乙酸乙酯,相对含量变化不大的有乙酸戊酯、2,6-二(1,1-二甲基乙基)-4-甲基苯酚等。

Abstract: The volatile compounds of“ Dajie”apricot juice and its fermented juice were extracted and identified with solid- phase micro extraction (SPME) and gas chromatography-mass spectrum (GC-MS). 57 from processed juice and 50 from fermented juice respective compounds were identified. 42 compounds were lost after fermentation but 35 new compounds produced. The relative contents of acetic acid hexyl ester, alpha-pinolene, apha-terpineol, tradecane, and dodecane decrease observably; alcohol and acetic acid ethyl ester increase after fermentation; the relative contents of acetic acid pentyl ester phenol, 2,6-bis(1,1- dimethylethyl)-4-methyl, 3-pentanol, 2,4-dimethyl icosane, docosane, beta-ionone, 2H-pyran, 2-ethenyltetrahydro-2,6,6- trimethyl, and 3-decyne did not change in content.
