Study on Differences in Aroma Constituent Content and Sensory Quality among Different Aroma-types and Genotypes of Flue-cured Tobacco

In order to study the differences in aroma constituent content and sensory quality among different aroma- types and genotypes of flue- cured tobacco,the author detected the contents of aroma constituents in the leaves of flue- cured varieties K326 and Yunyan 87 by using gas chromatography / mass spectrometry( GC / MS). The results indicated that there were large differences in aroma constituent content among flue- cured tobacco leaves from various aroma- type tobacco- growing areas,and the total content of aroma constituents revealed the following order: Guizhou Sichuan Henan. The content of aroma constituent in different genotypes of flue- cured tobacco was also different,Yunyan 87 had slightly higher aroma constituent content than K326 in Henan tobacco- growing area,and K326 had considerably higher aroma constituent content than Yunyan 87 in Guizhou tobacco- growing area; the aroma constituent content in Yunyan 87 in Huili of Sichuan was higher than that in K326,while that in K326 in Huidong of Sichuan was higher than that in Yunyan 87. The comprehensive evaluation of sensory quality of flue- cured tobacco by radar analysis considered that the tobacco leaves in Sichuan and Guizhou had better sensory quality,while those in Henan had worse sensory quality.
