烟丝及卷烟主流烟气中糖醇的离子色谱法检测与研究

Determination and Study of Sugar Alcohols in Cut Tobacco and Mainstream Smoke of Cigarette by Ion Chromatography

[目的]研究烟丝及卷烟烟气中糖醇对卷烟吸食品质的影响。[方法]采用离子色谱法分别对9个市售牌号的卷烟烟丝和主流烟气的糖醇进行定性和定量分析。[结果]卷烟烟丝与烟气中均含有肌醇、赤藓糖醇、木糖醇、阿拉伯糖醇、山梨醇、甘露糖醇6种物质;烟丝中肌醇含量最高,占其总量的50%～95%;烟气中糖醇的测定结果显示,不同种类糖醇的转移率有着较大差异,且卷烟主流烟气中糖醇含量已经达到甜味阈值的理论浓度。[结论]从改善卷烟吸食品质的角度来看,上述结果为糖醇在卷烟生产工艺中的应用提供了理论依据。

[Objective] To study the effect of sugar ：lcohols in cut tobacco and mainstream-smoke on the stnokin.g quality of cigarette. [Method] The ion eharomatogaphy was adopted to quantitatively and qualitatively analyze the sugar alcohols in cut tobacco and mainstream smoke of 9 sold cigttrettes. [ Result ] Inesitol,erythritol,xylitol,arabitol,sorbitul and mannitol existed in both the cut tobacco and mainstream smoke. In0situl con- tent was the highest of 50% -95% in cut tobacco;the sugar alcohols detection results showed that the transfer rate of sugar alcohols varied fitom type to type,and the contents of total sugar alcohols in mainstream smoke had reached sweet threshold value. [ Conclusion] From the perspective of improving the smoking quality of cigarette,the above research results provided rich theoretical support for the application of sugar alcohols in the production process of cigarettes.
