摘要
为了解影响不同含水率卷烟抽吸品质差异的因素，研究了不同相对湿度下平衡的卷烟烟丝含水率、燃吸品质、烟气粒相与气相水分及总粒相物挥发性成分的变化。结果表明：①随着平衡的环境相对湿度由30％上升到70％，烟丝含水率由8．28％上升到18．79％，卷烟的燃吸品质亦发生差、好、差的变化。其中，含水率12．25％和14．34％卷烟的燃吸品质均较好，含水率8．28％、9．13％、18．79％卷烟均较差；②随着烟丝含水率的升高，卷烟烟气粒相水分及气相水分均呈上升趋势，但气相水分的上升幅度较大；③总粒相物和烟碱含量随烟丝含水率增大而少量减少，CO量则明显增加；④含水率8．28％、12．25％和18．79％卷烟烟气粒相中均鉴定出相同的70种挥发性成分，但含水率8．28％卷烟的易挥发性化学成分含量较含水率12．25％卷烟高，而含水率18．79％卷烟则偏低。因此，含水率12％～14％卷烟具有较好的燃吸品质，环境湿度或烟丝含水率是影响卷烟烟气水分（尤其是气相水分）和低分子量易挥发性成分，乃至感官质量的重要因素。
In order to find the factors influencing the smoking quality of cigarettes with different moisture contents, the changes of moisture content in cut tobacco, smoking quality, moisture contents in particulate and gas phases and particulate volatile components in mainstream smoke of the cigarettes equilibrated in atmospheres of different relative humidities were studied. The results showed that： 1 ） when the circumstance＇ s relative humidity increased from 30% to 70% , the moisture content in cut tobacco increased from 8.28% to 18.79% , the smoking quality of cigarettes with moisture content of 12.25% and 14.34% was better than that with moisture content of 8.28% , 9.13% and 18.79% ; 2） the moisture contents in gas phase and particulate matters of cigarette smoke raised with the increase of moisture content in cut tobacco, while the moisture content in gas phase raised faster than that in particulate phase; 3） the total particulate matter and nicotine in cigarette smoke decreased slightly, while the CO increased obviously with the increase of moisture content in cut tobacco; 4） the same seventy volatile compounds were identified from the particulate matter in smoke of cigarettes with moisture contents of 8. 28%, 12. 25% and 18. 79%. Comparing with the total volatile compound content in cigarette with moisture content of 12.25% , that of 8.28% was higher, while that of 18.79% was lower. It was concluded that the smoking quality of cigarettes with moisture content between 12% and 14% was better, and atmospheric humidity or cigarette moisture content, would be an important factor affecting smoke moisture, especially gas phase moisture, lower-molecular-weight volatile components and smoking quality of cigarette.
