In order to improve cigarette quality, the volatile components in tobacco leaves of different varieties, grades, growing years and areas and cut tobacco of 3 modules making up blend A of Honghe brand series were analyzed with GC/MS. Based on the analysis results and desired product style and quality, the 3 modules were separately optimized, and the cigarette blend was modified. The results showed that: 1) in the original cigarette blend, modules of cut tobacco and tobacco leaf, the volatile components showed a uniform distribution trend in general, and the main volatile components were ketones, acids, alcohols, esters and alkenes; 2) the difference of volatile component content between tobacco leaves from different stalk positions, growing year, varieties and grades was obvious; 3) comparing with the original blend, the content of main aromatic components in the modified cigarette blend increased obviously, especially the content of ketones and alcohols raised by more than 10%, while that of aldehydes decreased by 9.21%; the results of sensory evaluation indicated that the quality of cigarette was improved and product style was as desired.
