摘要
采用吸烟机抽吸,结合GC-MS/MS和快速粒径仪检测,研究了6种香料在加热条件下向烟气气溶胶的迁移及对气溶胶理化特性的影响.实验结果表明:1)6种香料在350℃加热条件下均以原型蒸发为主.2)6种香料在加热抽吸时的释放迁移呈现不同特征,其中异戊酸异戊酯和2,3,5-三甲基吡嗪分布于烟气气溶胶粒相物和气相物中,其他4种香料均只分布于粒相物中;香叶醇和2-乙酰基吡咯向烟气气溶胶迁移的总迁移率为2.8%~8.1%,其余4种香料为17.6%~54.4%.3)与空白对照样相比,添加5%的L-薄荷醇或1%、2%的WS-23后,使烟碱、丙二醇和丙三醇向烟气气溶胶中的释放量降低了20%以上,在滤嘴段的截留量降低了10%以上.4)当L-薄荷醇添加量达5%时,气溶胶粒数浓度降低了28%、粒数中值直径(CMD)增大了8%.
The migration of six flavourings to smoke aerosols and their effects on the physical and chemical properties of aerosols under heating condition were studied by using a smoking machine,combined with GC-MS/MS and fast particulate spectrometer.The results showed that:1)The six flavourings were mainly evaporated by prototype at 350℃.2)The release and migration of the six flavourings showed different characteristics under heating and suction conditions.Isoamyl isovalerate and 2,3,5-trimethylpyrazine were transferred to particle phase and gas phase of aerosol,while the other four flavourings were only transferred to particle phase of aerosol.The total migration rates of geraniol and 2-acetylpyrrole to smoke aerosol were 2.8%~8.1%,and the other four flavourings were 17.6%~54.4%.3)Compared with the blank control,after adding 5%L-menthol or 1%and 2%WS-23,the release amount of nicotine,propylene glycol and glycerol from the tobacco materials to the aerosol was reduced by more than 20%,and their interception in the filter section was reduced by more than 10%.4)When L-menthol was added to 5%,the particle number concentration decreased by 28%and count median diameter(CMD)increased by 8%.
