摘要:采用正交实验优化添加肉桂微粉的稠浆法烟草薄片（CRT）制备工艺参数，对比其与对照样（RT）的感官质量、形貌结构、热解燃烧特性及卷烟主流烟气释放特征。结果表明，最佳成型工艺参数为以烟粉质量为基准，加水量550%、阔叶木浆纤维添加量4.00%、羧甲基纤维素钠添加量1.00%、流延厚度0.9 mm、干燥温度80 ℃，CRT的辛香特征风格彰显，香气量和质感提升；CRT的色泽朝亮度减小、红色调增加方向发展，表面光滑油润；肉桂微粉添加对CRT热解过程影响较小，但对燃烧过程影响较大，降低了燃烧焦炭阶段的质量损失速率并提升了综合燃烧特性指数；添加肉桂微粉使卷烟主流烟气粒相物中香味物质释放量由1 713.58 μg/支提升至2 003.81 μg/支，新增了肉桂醛及苯乙醛等特征成分释放。

Abstract:The orthogonal experiment was employed to optimize the preparation process parameters of slurry processed reconstituted tobacco sheet added with cinnamon micropowder (CRT). A comparative analysis was conducted between the CRT and the control sample (RT) in terms of sensory quality， morphological structure， pyrolysis and combustion characteristics， and mainstream cigarette smoke release profile. The results showed that the optimal process parameters were as follows (based on tobacco powder mass)： water addition amount of 550%， broadleaf fiber addition amount of 4.00%， carboxy methylcellulose soclium addition amount of 1.00%， casting thickness of 0.9 mm， and drying temperature of 80 ℃. The CRT exhibited a pronounced spicy characteristics with enhanced aroma quantity. Its color developed towards decreased lightness and increased red tone， presenting a smooth and oily surface. The addition of cinnamon micnpowder had a minor effect on the weight loss process during pyrolysis of the CRT but significantly influenced the combustion process. It reduced the weight loss rate of the coke stage in combustion stage and improved the comprehensive combustion characteristic index. Furthermore， the addition of cinnamon micopowder increased the release of flavor components in the particulate matter of mainstream cigarette smoke from 1 713.58 to 2 003.81 μg/cigarette， introducing the release of characteristic components such as cinnamaldehyde and phenylacetaldehyde.
