香料烟陈化过程中烟叶化学成分与品质变化的研究

Study on the changes of chemical components and quality of oriental tobacco leaf during aging

对香料烟陈化过程中烟叶化学成分和品质变化的研究结果表明,香料烟在陈化过程中烟叶淀粉、总N含量呈现出小幅度下降趋势,蛋白质含量有所下降,烟碱含量明显下降,还原糖含量表现为陈化前期下降而中后期有上升的趋势,不同香型、不同部位香料烟之间在化学成分含量的变化上存在着明显的差异;感官评吸结果表明,香料烟在陈化过程中总体感官质量及香型特征、香气质量、浓度、杂气、刺激性、余味和燃烧性等方面均有明显的改善,通过陈化过程,不同风格香料烟特有的属性特征充分显现。

Studies on the changes of chemical components and quality of oriental tobacco leaf during aging showed that the content of starch and total nitrogen decreased within a narrow range, the content of protein decreased to some extent, the content of nicotine decreased greatly, while the content of reduced sugar decreased in early stage and increased in middle and later stages. There were obvious differences in chemical components between oriental tobacco leaves of various aroma types or in different plant positions. Results of sensory evaluation indicated that in the aging process great improvement could be made as for overall sensory quality, aroma features, flavor quality, smoking concentration, offensive odor, biting taste, aftertaste, combustibility, and so on. The distinct attributes of various oriental tobaccos will be fully exhibited by aging.
