广元烤烟烟叶的特征香味成分研究

目的]分析广元烟区烟叶的特征香味成分,从致香物质角度探明广元烟叶的香型风格。方法]选取2014—2015年广元烟区20份烤烟样品(C3F),对其主要香味物质进行了分析,并与其他典型香型产区烟叶的致香物质进行了比较分析。结果]试验表明,广元烟叶香味物质总量丰富,五大类香味物质含量表现差异,其中新植二烯和苯甲醇含量较高;广元烟叶与三大香型典型产区烤烟的香味物质种类及含量也表现差异,与玉溪、许昌烤烟均差异显著,而与遵义烤烟差异不显著,且与遵义烤烟的相似系数最高。结论]研究可为广元烟区烤烟特色定位和烟叶生产提供参考。

Study on the Aroma Components of Flue-cured Tobacco Leaves in Guangyuan Tobacco-growing Areas

Objective] To analyze the characteristics and aroma components of tobacco leaves in Guangyuan tobacco area,and explore the aroma style of Guangyuan tobacco leaves from the perspective of aroma compounds.Method] A total of 20 flue-cured tobacco samples (C3F) from 2014 to 2015 in Guangyuan tobacco growing area were selected and their main aroma components were analyzed.The aroma compounds in leaves of other typical flavor producing areas were compared and analyzed.Result] Guangyuan tobacco aroma was abundant,five kinds of aroma components in high performance between 1,5-Hexadiene and benzene methanol plant; Guangyuan tobacco and 3 types of typical areas of tobacco aroma types and content also showed significant differences with Yuxi,Xuchang flue-cured tobacco,but the difference was not significant with Zunyi flue-cured tobacco,and similarity coefficient of Guangyuan flue-cured tobacco and Zunyi flue-cured tobacco was the highest.Conclusion] The study can provide reference for the characteristic location and tobacco production of flue-cured tobacco in Guangyuan tobacco growing areas.
