外加水溶性糖对卷烟烟气成分释放量的影响

Effect of Adding Water-soluble Sugar on the Release of Cigarette Smoke Components

[目的]系统考察外加水溶性糖对卷烟烟气常规成分和七害成分释放量的影响,[方法]以内源水溶性糖含量较高(C2F-DF2020,总糖30.84%)、较低(B3F-DH2020,总糖7.37%)的2种烤烟烟叶为参试对象,选用葡萄糖、蔗糖2种糖料,进行加糖量梯度试验(加糖量0%、2%、4%、6%、8%、10%),测定24个卷烟小样的烟气常规成分;在小样试验的基础上,以内源水溶性糖含量中等的(B2F-XG2018,总糖16.61%)烟叶为对象,进行中样试验(葡萄糖添加量0%、1%、3%、5%),测定4个卷烟中样的烟气常规成分和七害成分。[结果]小样试验结果显示,无论烟叶内源水溶性糖含量是高还是低,也无论外加糖源是葡萄糖还是蔗糖,烟气焦油量都不会随加糖量的增加而升高;中样试验结果显示,随着加糖量的增加,烟气焦油量不会随之升高,七害成分中含氮化合物如烟草特有NNK、HCN、氨等释放量呈下降趋势,卷烟危害性指数呈下降趋势。[结论]外加水溶性糖不会导致烟气焦油量和卷烟危害性指数升高。

[Objective]In order to systematically investigate the effect of added water-soluble sugar on tar and other harmful components of cigarette 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 ratios of 0(control),2%,4%,6%,8%,and 10%were added and the routine mainstream smoke indexes of 24 cigarette samples were determined;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 indexes 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.
