摘　　要：为了解有机酸对无序烟丝型加热卷烟烟碱释放行为的影响,采用GC-MS分析方法考察了添加不同质量分数的柠檬酸、酒石酸、苹果酸、乙酰丙酸、乳酸、丙酸和乙酸对加热卷烟总烟碱转移率、烟气总粒相物(简称烟气)pH及烟气中烟碱存在形式的影响。结果表明:(1)添加有机酸对加热卷烟总烟碱转移率没有明显影响。(2)添加非挥发性有机酸对烟气pH无明显影响;而添加挥发性有机酸使烟气pH略有降低,且随添加量增加,烟气pH持续下降。(3)添加非挥发性有机酸对烟气中游离态烟碱所占比例无明显影响;添加挥发性有机酸使烟气中游离态烟碱所占比例下降明显,且随添加量的增加,烟气中游离态烟碱所占比例持续下降。In order to investigate the effects of organic acids on releasing behavior of nicotine in heated tobacco products with randomly cut tobacco filling,GC-MS analysis method was used to analyze the influences of adding different mass fractions of citric acid,tartaric acid,malic acid,levulinic acid,lactic acid,propionic acid and acetic acid on the transfer rate of total nicotine,the pH of aerosol and the forms of nicotine in the aerosol of a heated tobacco product.The results showed that:1)The addition of these organic acids did not affect the transfer rate of total nicotine significantly.2)The pH of aerosol also did not change significantly after adding the non-volatile organic acids;however it decreased slightly and continuously with the increase of volatile organic acids.3)The proportion of free nicotine in the aerosol was not significantly influenced by the addition of non-volatile organic acids,while it decreased obviously and continuously with the addition of volatile organic acids.
