摘　　要：为研究气溶胶加热卷烟的成分和释放物特性,以2种气溶胶加热卷烟为对象,分析测试了芯基材和烟液中主要成分及其气溶胶释放行为。结果表明:①仅在芯基材中检出烟碱,其质量分数在11.04~20.21mg/g之间;②同品牌产品的芯基材和烟液中雾化剂1,2-丙二醇和丙三醇的质量分数和比例不同,烟液中雾化剂的质量分数高于芯基材;③样品A的消费形式接近电子烟,每10口气溶胶中烟碱的释放量随抽吸口数增加而下降,1,2-丙二醇、丙三醇的释放量在30口左右达到最大;样品B的消费形式接近电加热卷烟,气溶胶中烟碱和水分的释放量与电加热卷烟相当,雾化剂释放量显著提高;④总体而言,单位体积气溶胶中,样品A和B的气溶胶中烟碱的释放量低于中心加热型电加热卷烟iQOS,高于外周加热型电加热卷烟glo,而1,2-丙二醇和丙三醇的释放量均显著高于电加热卷烟,表明气溶胶加热卷烟或可弥补电加热卷烟烟雾量不足的问题。To investigate the chemical components and release characteristics of aerosol heated tobacco products(aHTPs),the main chemical components in the tobacco filler and e-liquid and the aerosol releases were studied for two selected aHTPs(coded as samples A and B).The results showed that:1)Nicotine was detected only in the tobacco filler with the mass fractions ranging from 11.04 to 20.21 mg/g of tobacco.2)The mass fractions and proportions of aerosol agents(1,2-propanediol and glycerin)in the tobacco filler and e-liquid of the same brand aHTP sample were different,and the mass fractions of 1,2-propanediol and glycerin were significantly higher in the e-liquid than in the tobacco filler.3)In the aerosol of the e-cigarette-like sample A,nicotine release gradually decreased per 10 puffs,the releases of 1,2-propanediol and glycerin reached the maximum around the 30th puff.The aerosol of eHTP-like sample B was compared to an eHTP,and it was found that nicotine and moisture releases were comparable to those of eHTPs,the releases of 1,2-propanediol and glycerin in aerosol from sample B were much higher than those from eHTPs.4)When normalized to per volume unit aerosol,the nicotine releases from samples A and B were lower than that from eHTP sample iQOS(a centrally heating type)but higher than eHTP sample glo(a peripherally heating type),while the releases of 1,2-propanediol and glycerin were significantly higher than those of eHTPs.These results suggest that aHTP may be designed to compensate for the insufficient aerosol amount of an eHTP.
