烟用接装纸中凉味剂的检测及释放行为分析

Detection and Release Behavior of Cooling Agents in Tipping Paper for Cigarettes

目的考察烟用接装纸中凉味剂的释放行为,为明确烟用凉味接装纸的贮存期提供参考。方法通过对样品前处理条件进行优化,采用气相色谱法测定接装纸中3种凉味剂的含量,基于该方法考察室温存放条件下各凉味剂的释放行为,并选取零级、一级、Higuchi和Korsmeyer–Peppas动力学模型对各凉味剂的释放行为进行拟合。结果接装纸中凉味剂最佳提取工艺条件为摇床辅助提取,提取溶液为乙醇,溶液体积为25 mL,提取温度为30℃,振荡转速为160 r/min,提取时间为25 min。在130 d时接装纸中(–)–薄荷酮和L–薄荷醇释放率达78.04%以上,(–)–乳酸薄荷酯释放率仅为39.74%;3种凉味剂在接装纸中的释放行为均符合Korsmeyer–Peppas动力学模型。结论文中方法适用于烟用凉味接装纸中(–)–薄荷酮、L–薄荷醇和(–)–乳酸薄荷酯的测定,较好地描述了3种凉味剂在接装纸中的释放过程,可为凉味型卷烟的品质监控和加工技术提供技术支撑。

The work aims to investigate the release behavior of cooling agents in tipping paper for cigarettes,so as to provide reference for clarifying the storage period of tipping paper for cigarettes.A gas chromatography method for de-termination of three cooling agents in the tipping paper was established by optimizing the pretreatment conditions of the sample.On this basis,the release behavior of each cooling agent under room temperature storage conditions was investi-gated,and the zero-level,first-level,Higuchi and Korsmeyer-peppas kinetic models were selected to fit the release be-havior of each cooling agent.The results showed that the optimal extraction process conditions for cooling agents were shaker-assisted extraction,ethanol extraction,the solution volume was 25 mL,the extraction temperature was 30℃,the rotation rate was 160 r/min,and the extraction time was 25 min.After 130 days,the release rate of(-)-menthone and L-menthol in the tipping paper reached 78.04%and that of(-)-menthyl lactate was only 39.74%.The release behavior of the three cooling agents in the tipping paper conformed to the Korsmeyer-peppas kinetic model.This method is suitable for the determination of(-)-menthone,L-menthol and(-)-menthyl lactate in cooling tipping paper for cigarettes.The three cooling agents are released quickly in the tipping paper and the process is affected by Fick diffusion.It is an effective method to analyze the release behavior of cooling agent in tipping paper by kinetic equation.
