甘油施加比例对加热卷烟水分、烟碱和甘油分布的影响

目的：优化加热卷烟烟草薄片的工艺参数。方法：制备了甘油添加比例为5%~30%的12个梯度等级的加热卷烟烟草薄片，制成加热卷烟烟支。使用GC-TCD方法检测加热卷烟烟气、滤嘴冷凝段和烟芯段中水分、烟碱和甘油质量，分析主要成分的质量分布特点，以及释放率、截留率和转移率。结果：加热卷烟烟草薄片在5%~30%甘油添加比例下，水分释放率较高为88.6%~92.3%，主要分布在烟气和滤嘴冷凝段；烟碱释放率次之，为25.5%~34.2%，主要分布在滤嘴冷凝段和烟芯段；甘油释放率最低，为13.9%~21.3%，主要分布在烟芯段。结论：当烟草薄片选择10%~18%的甘油添加比例时，加热卷烟的烟碱和甘油具有较高的转移率和较低的截留率。

Effects of glycerol application ratio on the distribution of moisture, nicotine and glycerol in heated cigarettes

Objective:In order to optimize the process parameters of tobacco sheet of heated cigarette. Methods:12 gradient grades of tobacco sheets with glycerol addition ratio of 5%~30% were prepared under laboratory conditions. The mass of moisture, nicotine and glycerol in heated cigarette smoke, filter condensation section and tobacco core section were detected by GC-TCD method. And the mass distribution characteristics of main components, release rate, filtration rate and transfer rate were analyzed. Results:When 5%~30% glycerol was applied to the heated cigarette tobacco sheets, the water release rate was 88.6%~92.3%, which was mainly distributed in the smoke and filter condensation section; The nicotine release rate was 25.5%~34.2%, which was mainly distributed in the filter condensing section and tobacco core section; The glycerol release rate was 13.9%~21.3%, which was mainly distributed in the tobacco core section. Conclusion:When 10%~18% glycerol was added to tobacco sheets, nicotine and glycerol in heated cigarettes had higher transfer rate and lower filtration rate.
