摘　　要：为研究薄板叶丝干燥过程“干头干尾”烟丝内在品质的变化规律，在正常生产情况下，以薄板叶丝干燥过程中的“干头千尾”烟丝为试验对象，检测了不同含水率“干头”、“干尾”烟丝样品的常规化学成分、多酚、pH值，采用聚类分析进行了分类，并结合感官评价进行了验证。结果表明：与正常生产的烟丝相比，“干头”、“干尾”烟丝含水率在9．00％～12．50％之间，烟丝化学成分和感官品质无明显差异；“干头”、“干尾”烟丝含水率〈9．00％，烟丝化学成分和感官品质有显著变化。烟丝含水率9．00％可作为“干头干尾”烟丝内在品质变化的临界点。In order to investigate the variation of intrinsic quality of over-dried cut tobacco produced in start and finish stags of thin plate drying process, the routine chemical components, polyphenolic compounds, pH value of over-dried cut tobacco with different moisture contents were determined, the obtained data were processed with cluster analysis. Meanwhile, sensory evaluation was conducted. The results showed that the chemistry and sensory quality of over-dried cut tobacco with the moisture content ranged from 9.00% to 12.50% did not obviously differ from those of normal dried cut tobacco, while those of cut tobacco with the moisture content less than 9.00% changed significantly. Therefore, the moisture content of 9.00% can be considered as the critical point of intrinsic quality variation of over-dried cut tobacco.
