不同原料稠浆法再造烟叶加热卷烟的气溶胶释放特性

  目的  研究稠浆法再造烟叶原料类型对加热卷烟气溶胶释放特性的影响。  方法  选取代表性类型烟叶为原料, 制成稠浆法再造烟叶并卷制成加热卷烟, 比较加热条件下释放的气溶胶粒数浓度、粒数中值直径(CMD)、烟雾量和香气成分。  结果  (1) 不同类型的上部烟叶, 粒数浓度为烤烟和晒黄烟高, CMD为晒黄烟、烤烟和香料烟大, 烟雾量为晒黄烟和烤烟大。(2)不同类型烟叶原料再造烟叶热解释放的香气成分差异明显, 白肋烟为原料的样品产生的茄尼酮、6-甲基-5-庚烯-2-酮、生物碱代谢物麦斯明和可替宁、吡嗪和吡啶类氮杂环物质多; 晒黄烟为原料的样品产生的5-羟甲基糠醛和糠醛等醛类、4-羟基-2, 5-二甲基-3(2H)-呋喃酮等酮类、糠醇、愈创木酚、麦斯明、可替宁多; 晒红烟为原料的样品产生的吡嗪类、生物碱代谢物多; 香料烟为原料的样品产生的苯乙醛多; 烤烟为原料的样品产生的香气成分大多处于居中水平, 且受烤烟香型和烟叶部位的影响。  结论  通过稠浆法再造烟叶原料的选用, 可改变产生的气溶胶粒径、浓度及香气成分释放量。 

Aerosol release characteristics of heated cigarettes made by slurry processed reconstituted tobacco with different tobacco materials

This study aims to study the effect of tobacco material type on the aerosol release characteristics of heated cigarette products made by slurry processed reconstituted tobacco. Heated cigarettes were made from slurry processed reconstituted tobacco with different tobacco materials, and the particle number concentration, the count median diameters(CMD), smoke amount and aroma components of aerosol released from them were compared under the heating condition. The results showed that: (1) For upper tobacco leaves, the particle number concentration of aerosol released from flue-cured tobacco and yellow sun-cured tobacco was higher, CMD of aerosol released from yellow sun-cured tobacco, flue-cured tobacco and oriental tobacco was larger, and smoke amount of aerosol released from yellow sun-cured tobacco and flue-cured tobacco was larger. (2) There were significant differences in aroma components released by pyrolysis of reconstituted tobacco from different tobacco material. The reconstituted tobacco sample with burley tobacco as raw material produced more solanone, 6-methyl-5-heptene-2-one, alkaloid metabolites such as myosmine and cotinine, pyrazines and pyridines in the pyrolysis, the sample with yellow sun-cured tobacco as raw material produced more aldehydes such as 5-hydroxymethylfurfural and furfural, ketones such as 4-hydroxy-2, 5-dimethyl-3(2H)-furanone, furfuryl alcohol, guaiacol, myosmine and cotinine, the sample using red sun-cured tobacco as raw material produced more pyrazines and alkaloid metabolites, and the sample with oriental tobacco as raw material produced more phenylacetaldehyde. Moreover, most of the aroma components produced by the sample with flue-cured tobacco as raw material were at the middle level, which were affected by the aroma type and leaf parts. The particle number concentration, particle size of aerosol and the release amount of aroma components produced from reconstituted tobacco under the heating condition can be changed by selecting different raw tobacco materials.
