Effect of Adding Water-soluble Sugar on the Release of Cigarette Smoke Components
[Objective]In order to systematically investigate the effect of added water-soluble sugar on tar and other harmful components of cig-arette smoke.[Method]Two kinds of flue-cured tobacco leaves with high water-soluble sugar content(C2F-DF2020,total sugar 30.84%)and low water-soluble sugar content(B3F-DH2020,total sugar 7.37%)were selected as the test objects,glucose and sucrose with the weight rati-os of 0(control),2%,4%,6%,8%,and 10%were added and the routine mainstream smoke indexes of 24 cigarette samples were deter-mined;on the basis of the above laboratory tests,take B2F-XG2018 tobacco leaf with medium content of water-soluble sugar(total sugar 16.61%)as the object,carry out the factory tests(glucose addition 0%,1%,3%,5%),and determined the routine mainstream smoke in-dexes and seven harmful components of four cigarette samples.[Result]The results showed that:no matter whether the content of endogenous water-soluble sugar in tobacco leaves was high or low,and whether the added sugar source was glucose or sucrose,the tar content of smoke did not increase with the increase of sugar addition;with the increase of sugar addition,the release of nitrogen compounds such as tobacco specific NNK,HCN,ammonia showed a downward trend,while the harm index of cigarettes showed a downward trend.[Conclusion]The addition of water-soluble sugar will not lead to the increase of tar content and 7 harmful components in smoke.
