| 摘 要： | 为探讨做青对乌龙茶香气形成的作用，采用ＸＡＤ－２吸附剂捕集香气、ＧＣ和ＧＣ／ＭＳ分析，对乌龙茶做青及晒青工序的香气变化进行了研究。结果表明，晒青能增加香气组分数和香精油总量，做青则能改变低沸点和高沸点香气组分含量的比例；乌龙茶摇青工序中产生的花香特征化合物为，苯甲醇，橙花叔醇，水杨酸顺－３－己烯酯，邻苯二甲酸二丁酯和两种未鉴定的组织。

| Abstract: | In order to examine the effect of the rotating process on the aroma forming of Oolong tea,XAD 2 was used to absorb the headspace of samples and the headspace analyzed by GC and GC/MS. The results showed:the numbers of constituents and the total of essential oil were increased after sunny withering treatment;the rate of the low and high boiling point compounds was changed during rotating process:the characteristic aroma constituents of rotating leaves were benzyl alcohol,nerolidol,cis 3 hexenyl salicylate,benzenedicarboxylic acid dibutyl ester and two unidentified compounds. |
