Abstract：To expand the core flavor source of heated cigarettes,flue-cured tobacco,sun-cured yellow tobacco,burley tobacco and oriental tobacco were selected as raw materials to prepare flavors by dry distillation process.Firstly,the contents of conventional chemical components in four kinds of tobacco leaves were determined.Then,the dry distillation flavors were prepared and the extraction rate was calculated.The composition differences of volatile components were explored by GC-MS and principal component analysis.Finally,the aroma-enhancing effect was evaluated by sensory evaluation.The results showed that the nicotine and total nitrogen contents of burley tobacco were significantly higher than those of other tobacco leaves,the total sugar and reducing sugar contents of sun-cured yellow tobacco were the highest,and the chemical components of flue-cured tobacco were more balanced.The extraction rate of dry distillation perfume was 2.8%for flue-cured tobacco,2.7%for oriental tobacco,2.5%for sun-cured yellow tobacco and 1.5%for burley tobacco.A total of 205 volatile components were identified by GC-MS,and the total contents were 7 024.00µg/g for flue-cured tobacco,1 407.79µg/g for sun-cured yellow tobacco,3 881.90µg/g for burley tobacco and 6 951.56µg/g for oriental tobacco,respectively.Phenols,ketones and heterocyclic compounds were the main aroma components.Principal component analysis showed that the aroma components of flue-cured tobacco and oriental tobacco were similar,while burley tobacco and sun-cured yellow tobacco were significantly different.The sensory evaluation showed that the addition of dry distillation flavors could improve the smoking quality of heated cigarettes.Among them,the effect of flue-cured tobacco dry distillation flavor was the best,and the improvement effect was significant in aroma quantity,sweetness and strength.In summary,the aroma components of flue-cured tobacco are coordinated,the content of volatile components is high,and the burnt sweet and smoked aroma are prominent,which can effectively make up for the problem of insufficient aroma release of heated cigarettes.
