摘　　要：为优化初烤烟叶的分切利用技术,制备了云南和河南产区不同单叶重梯度烟叶,并利用三段式分切法研究了烟叶不同分切区位的化学成分和感官品质差异及不同单叶重对分切后烟叶品质差异的影响。结果表明:不同分切区位烟叶还原糖含量(质量分数)、氯含量、钾氯比值、两糖比值差异变化规律在不同产区间表现一致。叶基部还原糖含量较低,氯含量较高,钾氯比值和两糖比值较低,叶尖部和叶中部氯含量和钾氯比值变化存在一定差异。河南产区叶基部的感官品质低于叶中部和叶尖部,云南产区在单叶重大于20 g时,叶基部感官品质明显下降。各产区在低单叶重水平下,不同分切区位烟叶化学成分含量和感官品质变异较小,单片烟叶的品质均匀性较好。氯含量、两糖比值差异与河南产区不同分切区位烟叶感官品质的差异密切相关。因此,可将单叶重分类与烟叶分切利用技术相结合,以提高烟叶资源的利用率。To optimize the cutting and utilization of cured leaves of flue-cured tobacco,tobacco leaves of different single leaf weights were collected from Yunnan and Henan producing areas,and the differences in chemical compositions and sensory quality of different sections of the tobacco leaves were investigated through a three-section cutting experimental design.The results showed consistent variations in reducing sugar and chlorine contents(mass fractions),potassium/chlorine ratio,and reducing sugar/total sugar ratio of different sections of tobacco leaves from Yunnan and Henan producing areas.Reducing sugar content,potassium/chlorine ratio and reducing sugar/total sugar ratio were lower,and chlorine content was higher in the base section of the tobacco leaf.The variations of chlorine content and potassium/chlorine ratio differed between the tip section and middle section of the leaf.The sensory quality of the base section was lower than that of the middle and tip sections for Henan tobacco leaf,while the sensory quality of the base section of Yunnan tobacco leaf deteriorated significantly when single leaf weight was higher than 20 g.At lower single leaf weight,the differences in chemical composition and sensory quality were minor among the different leaf sections from the same producing area,and the quality consistency of a single leaf was better.Chlorine content and reducing sugar/total sugar ratio were closely correlated to the difference in sensory quality of different sections for Henan tobacco leaf.Therefore,the utilization rate of tobacco leaves could be promoted by combining leaf classification based on single leaf weight with leaf sectioning technology.
