摘要:为深入分析Marlboro-IQOS中心加热型加热烟草卷烟芯材（简称IQOS芯材）的结构和设计，本研究选取6种IQOS芯材样品进行微观结构、理化性能及无机元素含量等指标的测试分析。结果表明，IQOS芯材是由混合浆料体系在一定的压力作用下堆积而成，具有较低的平均纤维长度和宽度、较高的细小纤维含量、细小纤维面积百分比及纤维粗度；IQOS芯材的切丝宽度为0.5 mm，填充密度达0.615 g/cm³；热水可溶物含量在61.51%~67.99%的范围，平均值达63.69%；IQOS芯材除总植物碱之外的有机化学成分含量较低，其高含量的总植物碱为人工添加；IQOS芯材的灰分平均值为9.98%；无机元素分析表明，IQOS芯材中可能添加含镁和铝等金属盐的燃烧调节剂和传热材料；甘油和丙二醇为IQOS芯材产品的主要烟雾生成剂，平均总含量为13.79%；IQOS芯材的感官质量更依靠人为添加的挥发性香味物质。

Abstract:In order to further investigate the structure and design of core material for central heated tobacco， six kinds of central heated tobacco core materials of Marlboro IQOS brand were selected to analyze the microstructure， physicochemical properties， and inorganic element content of samples. The results showed that core material was composed of a mixed slurry system stacked under certain pressure， with lower average fiber length and width， but higher fine fiber content， percentage of fine fiber area， and fiber coarseness， The cutting width of the core material was 0.5 mm， and the filling density reached 0.615 g/cm³. The content of hot water soluble substances in core material ranged from 61.51% to 67.99%， with an average value of 63.69%. The organic chemical composition of core material was relatively low except for total alkaloids， and the high content of total alkaloids was artificially added. The average ash content of the core material was 9.98%， and inorganic element analysis indicated that it may contain combustion regulators and heat transfer materials containing metal salts such as magnesium and aluminum. Glycerol and propylene glycol were the main smoke generating agents for core material， with an average total amount of 13.79%. The sensory quality of the core material was relatively more dependent on artificially added volatile aroma compounds.
