摘要: 采用同时蒸馏萃取结合气相色谱-质谱联用技术分析烟用香精中的挥发性成分,利用气相色谱-质谱-嗅觉检测器联用技术结合香气提取稀释分析确定其香气活性成分,同时对香气活性成分进行定量分析并计算其香气活性值,通过香气重组实验与缺失实验确定烟用香精的关键性香气活性成分.结果表明:在烟用香精中共鉴定出54种挥发性成分,其中有22种香气活性成分;结合香气稀释因子和香气活性值确定了17种重要香气活性成分;最终确定烟用香精中的关键香气活性成分为β-大马酮、芳樟醇、乙基麦芽酚、乙酸芳樟酯、乙酸橙花酯、月桂烯、橙花醇、乙酸香叶酯、D-柠檬烯、苯甲醇.

Abstract: The volatile chemical components of tobacco flavor were prepared by simultaneous distillation extraction and analyzed using gas chromatography-mass spectrometry.The aroma-active violates were determined by means of gas chromatography-mass spectrometry-olfactometry combined with aroma extraction dilution analysis,and the important odorants were further screened out according to quantitative study and odor activity values.Aroma recombination and omission experiments identified the key odorants of the tobacco flavor.The results exhibited that simultaneous distillation extraction of tobacco flavor included 54 kinds of volatile compounds,including 22 aroma-active compounds,and 17 odorants were screened out as the predominant odorants according to flavor dilution factors and odor activity values.β-damascarone,linalool,ethyl maltol,linalyl acetate,neryl acetate,myrcene,nerol,geranyl acetate,D-limonene,and benzyl alcohol were confirmed as the key odorants of tobacco flavor.-
