摘　　要：【目的】探究稠浆法烟草薄片中甘油含量对加热卷烟烟气中挥发/半挥发性香味成分释放的影响。【方法】采用GC/MS分析加热卷烟烟气中179种挥发/半挥发性香味成分的释放量,对甘油含量与各香味成分的单位干基释放量进行相关性分析。【结果】(1)甘油含量从9.36%增加到28.40%,挥发/半挥发性成分释放总量先上升后下降,与甘油含量呈二次函数变化关系,R2为0.9199。(2)烟气中羧酸类、醛酮类、酚类、酯类、内酯类及氮杂环类物质的释放量随甘油含量的增加呈二次函数变化,相关系数R2分布在0.8453~0.9465,烃类物质释放量与甘油含量呈线性变化关系,R2为0.9618。(3)低沸点且与甘油容易形成氢键的成分,其释放量与甘油含量呈正相关,而含有长烷烃链或者大位阻取代基的高沸点类物质释放量与甘油含量一般呈弱相关。所检出的香味成分中,单位干基释放量与甘油施加量呈显著正相关的有12种。This study aims to explore the effect of glycerol content in reconstituted tobacco made by slurry process on the release of volatile/semi-volatile aromatic components from heated cigarette smoke.To this end,GC/MS method was used to analyze the release of 179 volatile/semi-volatile aromatic components in heated cigarette smoke and correlation analysis was carried out with the unit dry basis release of each aroma component.The results showed that:1)When the glycerol content increased from 9.36%to 28.40%,the total release of volatile/semi-volatile aromatic components firstly increased and then decreased,forming a quadratic function with the glycerol content.2)The release of carboxylic acids,aldehydes and ketones,phenols,esters,lactones and nitrogen heterocyclic substances in the smoke changed quadraticly with the increase of glycerol content,where the correlation coefficient change from 0.8453 to 0.9465.Moreover,the release amount of hydrocarbon substances had a linear relationship with the glycerol content,where R2 was 0.9618.3)The component that has a low boiling point and is easy to form hydrogen bonds with glycerol had a positive correlation with the glycerol content,while those containing long alkane chains or large steric substituent with high boiling point were weakly correlated with the glycerol content.Of the detected aromatic components,12 were significantly positively correlated with the glycerol content.
