烤烟烟叶和造纸法再造烟叶主流烟气成分对比分析

Comparative Analysis of Mainstream Smoke Components in Flue-cured Tobacco Leaves and Paper-making Reconstituted Tobacco Leaves

对比分析烤烟烟叶、造纸法再造烟叶主流烟气成分含量的差异,并剖析影响造纸法再造烟叶感官质量的关键成分,为造纸法再造烟叶品质的改善提供方向。结果表明,3种香型烤烟烟叶、再造烟叶主流烟气成分含量有较显著的差异,主要表现为造纸法再造烟叶主流烟气中醛类、醇类含量高于烟叶,而有机酸、糖类、氮杂环类、氧杂环类含量低于烟叶;进一步对比国内外再造烟叶发现,国外造纸法再造烟叶产品感官质量得分和烟气pH显著高于国内产品。结合余弦相似的理论分析发现烟气中吡啶类、呋喃酮类化合物与感官质量指标中木质气、烧纸气有一定的相关性。

In order to improve the sensory quality of reconstituted tobacco sheet,the main stream smoke of tobacco and paper-making reconstituted tobacco leaves was researched.The results showed that the content of the mainstream smoke components in flue-cured tobacco and reconstituted tobacco leaves varied significantly;the content of aldehydes and alcoholsin paper-making reconstituted tobacco leaves was higher than that of tobacco,while the content of organic acids,sugars,nitrogen heterocyclic compounds and oxygen heterocyclic compounds was lower;the sensory quality scores and the smoke pH of foreign product was significantly superior toother products;the pyridines and furanones in the smoke were negatively correlated with the odour of burning paper taste by the analysis of cosine similarity.
