调节湿度对国外两款市售加热卷烟烟气主要成分逐口释放行为的影响

Effects of conditioning humidity on puff-by-puff releases of main aerosol components from two foreign commercial heated tobacco products

为了解调节湿度对加热卷烟(Heated tobacco products,HTPs)烟气释放行为的影响,以市售的两款典型加热卷烟(HTP-1,配套中心加热器具;HTP-2,配套外周两段式加热器具)为研究对象,考察了不同调节湿度下加热卷烟烟气主要成分的逐口释放量,并讨论了调节湿度对两款烟支烟气逐口释放行为的影响规律。结果表明:①两款加热卷烟烟气具有各自特有的逐口释放行为,调节湿度对两款加热卷烟烟气不同成分逐口释放行为的影响既有规律性,也有特殊性;②随调节湿度增大,两款烟支相同抽吸口数序号的前几口烟气烟碱、烟气甘油释放量减少,相同口数序号的烟气水分释放量增加;③不同调节湿度对HTP-1烟气烟碱、烟气甘油的逐口释放趋势以及对烟碱逐口所占比例随抽吸口数序号的变化趋势有明显影响,但对HTP-2烟气各成分的逐口释放趋势和逐口所占比例随抽吸口数序号的变化趋势均没有明显影响。

In order to investigate the effects of conditioning humidity on the release of aerosols from heated tobacco products(HTPs),the puff-by-puff releases of main aerosol components from two representative commercial HTPs(HTP-1,equipped with central heating device;HTP-2,equipped with peripheral two-section heating device)were determined at different conditioning humidity ranges.Moreover,the influences of conditioning humidity on the puff-by-puff release behaviors of aerosols from those two HTPs were discussed.The results showed that:1)Both of the two HTPs had their own special puff-by-puff release behaviors and the influences of the conditioning humidity on the puff-by-puff release behaviors of different aerosol components from the two HTPs had regularity as well as particularity.2)With the increase of the conditioning humidity,the releases of nicotine and glycerin decreased and moisture release increased at the same puff for the first few puffs.3)Conditioning humidity parameters had obvious influence on the puff-by-puff release trends of nicotine and glycerin in the aerosols from HTP-1,as well as on the variations of nicotine/ACM(the ratio of nicotine to aerosols collected matter)with the proceeding puffs for HTP-1,while it had less influence on those of HTP-2.
