滤棒载香型卷烟中柠檬烯的烟气转移行为及贮存稳定性研究

Study on Smoke Transfer Behavior and Storage Stability of Limonene in Filter Rod Flavored Cigarettes

为明确滤棒载香型卷烟在不同贮存时间下柠檬烯的烟气转移行为、贮存稳定性和感官品质,以滤嘴中负载橘皮颗粒的滤棒载香型卷烟为研究对象,采用气相色谱-质谱(GC-MS)分析方法,测定主流烟气常规成分释放量,分析贮存和抽吸过程中柠檬烯的含量变化并评价感官质量。结果表明,橘皮颗粒能够降低卷烟烟气中焦油、烟碱及总粒相物的释放量。贮存期内柠檬烯的滤棒持留率、主流烟气粒相物转移率以及烟蒂截留率分别介于65.10%~100.00%、8.60%~14.48%和76.29%~85.17%,且随贮存时间延长均呈降低趋势,而气相转移率变化趋势不明显;贮存期在20~180 d内柠檬烯在烟支及烟气中衰减率的差异性不显著;不同贮存期卷烟中柠檬烯的逐口转移率介于0.22%~3.97%,在贮存期10~180 d内柠檬烯的逐口转移率趋于稳定,逐口转移率随抽吸口数的增加而升高,随贮存时间延长而减小并趋于平缓,且在贮存期内逐口释放率与抽吸口数存在良好的线性关系。负载橘皮滤棒的卷烟果香突出,贮存期内特征香韵强度减弱缓慢,感官品质较为稳定。

To study the smoke transfer behavior,storage stability and sensory quality of limonene in the filter rod flavored cigarettes loaded with orange peel particles under different storage time,gas chromatography-mass spectrometry(GC-MS)was used to determine the release of conventional components in mainstream flue gas,analyze the change of limonene content during storage and suction,and evaluate the sensory quality.Orange peel particles could significantly reduce the release of tar,nicotine and total particulate matter in cigarette smoke.During the storage period,the filter rod retention rate of limonene,the transfer rate of particulate matter in mainstream smoke and the retention rate of cigarette butts ranged from 65.10% to 100.00%,8.60% to 14.48% and 76.29% to 85.17%,respectively,and showed a decreasing trend with the increase of storage time,while the change trend of gas phase transfer rate was not obvious;and the difference of limonene decay rate in cigarettes and smoke was not significant within 20—180 d;the puff-by-puff transfer rate of limonene was between 0.22% and 3.97%,which increased with the increase of the number of suction ports,decreased and tended to be flat with the extension of storage time,and there was a good linear relationship between the puff-by-puff release rate and the number of suction ports during the storage period,and the puff-by-puff transfer rate of limonene tended to be stable within 10—180 d of the storage period.The filter rod flavored cigarettes had outstanding fruit aroma,the characteristic aroma intensity weakened slowly during the storage period,and the sensory quality was relatively stable.
