| 摘 要： | 本文采用固相微萃取与GC-MS联用对4种年份的镇江香醋香气成分进行了分析鉴定,共得到52种成分,主要是酸、酯、醇、酮和杂环类化合物,其中乙酸、乙酸乙酯、糠醛和四甲基吡嗪的含量较高,它们都占到总香气含量的50%以上,可能对镇江香醋的香气产生较大的影响。随着后熟时间的增加,镇江香醋香气成分的数量呈下降趋势。同时,对镇江香醋香气形成的机理进行了探讨。

| Abstract: | The aroma components of four Zhenjiang Fragrance Vinegars produced in different years were analyzed by GC-MS method combined with solid-phase microextraction, 52 aroma components were identified, which mainly were acids, esters, alcohols, ketones and herterocylic compounds. Among them, the contents of acetic acid, ethyl acetate, furfltral and tetramethyl pyrazine reached above 50% in all, which possibly affected the aromatic quality of Zhenjiang Fragrance Vinegar. The research showed that the aroma components of Zhenjiang Fragrance Vinegars decreased during aging process. Also, the mechanisms of aroma formation of Zhenjiang Fragrance Vinegar were studied. |
