沟槽滤嘴对卷烟香气的选择性截留研究

摘要

Normal acetate fiber filter,inside grooved filter and outside grooved filter were chosen as objects in the research.Cigarettes were smoked by smoking machine and a method of SDE-GC/MS was used to analyze flavor composition of extraction liquid.Quantitative and relative analysis was made via data analysis method.The results showed that the number of common and minor error flavor in filter and Cambridge filter was 96.To all kinds of flavors,the retention efficiency of grooved filter was higher than normal acetate fiber filter.Retention of flavor compounds in mainstream smoke showed strong selectivity.The selectivity was mainly positive,but changed with different filters.%以普通醋纤、内沟槽、外沟槽3种滤嘴作为研究对象,使用吸烟机抽吸卷烟后,同时蒸馏萃取滤片和滤嘴,GC/MS分析萃取液中香气成分,用数据分析方法进行定量分析.结果表明:①滤嘴和剑桥滤片中共有且平行试验相对误差较小的香味物质共96种;②对各类香味成分的截留效率都是沟槽滤嘴高于普通醋纤滤嘴;③卷烟主流烟气中香气成分的截留表现为较强的选择性,且以正向选择为主,但其选择性又会因滤嘴而异.
