摘　　要：为通过分析致香成分探索不同产地雪茄烟样品的差异,测定了国内外47个雪茄烟样品的共79种致香成分,并通过显著性检验比较了古巴雪茄、国外非古巴雪茄和中国雪茄致香成分质量分数和气味活性值的差异。结果表明:①43种致香成分的质量分数在不同产地雪茄烟间差异显著,其中α-姜黄烯和雪松醇的差异最显著。古巴雪茄的叶绿素和西柏烷类降解物的量相对较高,国外非古巴雪茄的苯丙氨酸类和赖百当类降解物的量相对较低,中国雪茄的叶绿素降解物的量较低。②79种致香成分的水果和花香风味的气味活性值较高,古巴雪茄的草药香料、水果、花香和其他风味的气味活性值较大。国外非古巴雪茄的植物、水果、坚果、花香和其他风味的气味活性值较低。③以致香成分质量分数为变量建立的判别函数,可对雪茄烟的产地进行区分。In order to investigate the leaf aroma chemical differences for cigar samples from different producing areas,79 aroma components in 47 cigar samples from different countries were determined.In addition,the differences in contents and odor activity values of aroma components among Cuban cigars,foreign non-Cuban cigars and Chinese cigars were compared by significance tests.The results showed that:1)There were significant differences in the contents of 43 aroma components among the cigars from different producing areas,and the differences in the contents ofα-curcumene and cedrol were the most significant.The contents of degradation products from chlorophyll and cembranoids in Cuban cigars were higher,those of phenylalanines and labdanums in foreign non-Cuban cigars and that of chlorophyll in Chinese cigars were lower.2)The 79 aroma components had higher odor activity values in fruit and flower flavors.Cuban cigars had higher odor activity values in herbal spices,fruit,flower and other flavors.Foreign non-Cuban cigars had lower odor activity values in plant,fruit,nut,flower and other flavors.3)The discriminant functions established by taking the contents of aroma components as variables could distinguish the producing areas of commercial cigars.
