空腔直径对圆形空腔滤棒卷烟烟气及感官品质的影响

Effect of cavity diameter on the mainstream smoke and sensory quality of cigarettes with circular cavity combined filter rods

在空腔深度相同的条件下,设计4种不同空腔直径的圆形空腔滤棒,并研究了空腔直径对卷烟主流烟气释放、有害物质截留及感官品质的影响。结果表明:圆形空腔滤棒卷烟的总粒相物、焦油、烟碱释放量随空腔直径的增加而提高,并且均高于普通醋纤滤棒卷烟的释放量;圆形空腔滤棒中普通丝束段的烟碱截留量基本无变化,而空腔丝束段的烟碱截留量与单位面积烟碱截留量随空腔直径的增加逐渐减小;随空腔直径增大,圆形空腔滤棒卷烟的危害性指数逐渐增加,卷烟危害性指数偏移量逐渐增大,但卷烟的感官品质评价得分逐渐减小。

Under the condition of the same cavity depth,four circular cavity combined filter rods with different cavity diameter were designed,and the influence of cavity diameter on the main physical and chemical indexes and sensory quality of cigarettes was studied.The results showed as follows:the release amounts of total particulate matter,tar and nicotine of circular cavity combined filter cigarettes increased with the increase of cavity diameter,and were higher than those of cigarettes with ordinary cellulose acetate filters.The nicotine interception in ordinary tow segment had little change,while the nicotine interception in the tow segment of the cavity filter rod and the nicotine interception per unit area gradually decreased with the increase of the cavity diameter.With the increase of cavity diameter,the hazard index of combined filter cigarettes increased,and the offset of cigarette hazard index gradually increased.The sensory quality evaluation score of combined filter cigarettes decreased with the increase of the cavity diameter.
