Difference Analysis of Aroma Compounds in Mainstream Smoke of Cigarette Made of Cut Stem or Cut Leaf of Flue-cured Tobacco
The comparative analysis of aroma compounds in the mainstream smoke of cigarettes which were made of cut stem or cut leaf of flue-cured tobacco was carried out, in order to provide theoretical references for the application of cut stem in ciga-rette blending design and tar reduction. The stems and leaves of flue-cured tobacco were selected from Qujing city of Yunnan province, they were cut and made into cigarettes, and the differences in ninety-four kinds of aroma compounds in mainstream smoke between two types of cigarettes were analyzed. The results indicated that:for a single cigarette, the total yield of 22 kinds of basic aroma components in mainstream smoke of cut-stem cigarette was about one fifth of cut-leaf cigarette;except for 2,6-dime-thylpyrazine, the content of other 21 kinds of basic aroma components in mainstream smoke of cut-stem cigarette was all lower than that of cut-leaf cigarette;the total yield of 47 kinds of neutral aroma components in mainstream smoke of cut-stem cigarette was about half of cut-leaf cigarette; the content of 42 kinds of neutral aroma components in mainstream smoke of cut-stem ciga-rette was all lower than that of cut-leaf cigarette; the total yield of 25 kinds of acidic aroma components in mainstream smoke of cut-stem cigarette was about one twentieth of cut-leaf cigarette;the content of all acidic aroma components in mainstream smoke of cut-stem cigarette was all lower than that of cut-leaf cigarette. For tar per unit, the total yield of basic aroma components in mainstream smoke of cut-stem cigarette was about half of cut-leaf cigarette;the content of 14 kinds of basic aroma components in mainstream smoke of cut-stem cigarette was obviously lower than that of cut-leaf cigarette;the total yield of neutral aroma compo-nents in mainstream smoke of cut-stem cigarette was similar to that of cut-leaf cigarette;the content of 34 kinds of neutral aroma components in mainstream smoke of cut-stem cigarette was markedly lower than that of cut-leaf cigarette;the total yield of acidic aroma components in mainstream smoke of cut-stem cigarette was about one seventh of cut-leaf cigarette;except for valeric acid, the content of other 24 kinds of acidic aroma components in mainstream smoke of cut-stem cigarette was evidently lower than that of cut-leaf cigarette. When cut-stem blending technology was applied in reducing cigarette tar, the flavor compensation and aroma enhancement technologies should be pertinently used to reduce the loss of aroma compounds in mainstream cigarette smoke.
