摘要
以2010年云南省楚雄州九县一市10个生态区的K326品种C3F等级烟叶为原料,采用GC/MS联用仪对烤烟致香成分含量进行了分析,结果表明:GC/MS测定共检测出64种挥发性致香物质,其中,有28种成分在不同生态区间呈极显著差异(P<0.01),5种呈显著差异(P<0.05);按香气前体物分成6类,类西柏烷类物质总量、新植二烯和其他类总量呈极显著差异,棕色化反应产物类总量呈显著差异,类胡萝卜素降解产物总量和苯丙氨酸类总量没有显著差异。致香物质总量和新植二烯总量禄丰最高,类西柏烷类物质总量和其他类总量牟定最高。根据致香物质组分进行主成分分析排序:牟定>禄丰>大姚>武定>双柏>永仁>南华>元谋>楚雄>姚安;将楚雄州10个不同生态区进行聚类分析划分为4类:南华、双柏、武定、永仁、元谋和楚雄一类;大姚和禄丰一类;牟定和姚安各为一类。
Aroma components of tobacco leaves after flue-curing from K326 among different Chuxiong tobacco planting areas were analyzed with the method of gas chromatography-mass spectrometry(GC/MS). The Results showed that: 64 kinds of aroma components were tested, 28 components and 5 components had significant differences respectively(P<0.01, P<0.05) in different ecological areas; there were 6 categories according to fragrant precursor, cembrane degradation contents, neophytadiene and other aroma components had significant differences(P<0.01), as well as maillard reaction contents(P<0.05), while carotenoids degradation contents and aromatic amino acid degradation contents had no significant difference. The total contents and neophytadiene in Lufeng area is superior to others, cembrane degradation contents and other aroma components in Mouding area is superior to others. Sequences of aroma components according to principal component analysis method were: Mouding>Lufeng>Dayao>Wuding>Shuangbo>Yongren>Nanhua>Yuanmou>Chuxiong>Yaoan; through the clustering analysis of the 10 main tobacco- growing areas in Chuxiong Autonomous Prefecture: Nanhua, Shuangbo, Wuding, Yongren, Yuanmou, Chuxiong were clustered into a group, Dayao and Lufeng were clustered into a group, Mouding and Yaoan were divided into other group respectively.
