摘　　要：为探索制丝过程中不同档次卷烟配方叶组化学成分及相关酶活性的变化,分析了制丝过程的6个生产工序高、中、低档烤烟型卷烟配方叶组的多酚、淀粉、总糖、还原糖、烟碱、总氮含量以及多酚氧化酶和淀粉酶活性。结果表明:①在制丝过程的6个工序中,除贮片工序还原糖含量略有增大外,高、中、低档卷烟配方叶组的多酚、淀粉、总糖、还原糖、烟碱和总氮均持续降低;②多酚氧化酶活性和淀粉酶活性从投料口至第1次润叶后均有所增加,之后工序中多酚氧化酶活性持续降低,淀粉酶活性至贮片工序后仍有所增加,之后持续降低;③在制丝过程的6个工序中配方叶组的多酚、总糖及还原糖含量、碱氮比及糖碱比与最佳值接近程度、淀粉酶活性与其卷烟档次成正比,而烟碱、总氮、淀粉含量及多酚氧化酶活性与其卷烟档次成反比。In order to investigate the changes of chemical components and relative enzymatic activities in blended tobacco of cigarette of different price tiers during primary processing,the contents of polyphenols,starch,total water-soluble sugar, reducing sugar,nicotine,total nitrogen and the activities of polyphenol oxidase and amylase in blended tobacco of cigarettes of high,middle and low price tiers were determined at 6 steps of primary processing.The results showed that： 1） the contents of polyphenols,starch,total sugar,reducing sugar,nicotine,and total nitrogen decreased continuously,except that of reducing sugar,which slightly increased in strips in bulking silo;2） the activities of polyphenol oxidase and amylase increased from feeding through first conditioning,after that polyphenol oxidase activity decreased continuously,while amylase activity increased until leaving the bulking silo,then decreased continuously;3） during primary processing,the degree of the contents of polyphenols,total sugar,reducing sugar,ratio of alkaloid to nitrogen and ratio of sugar to alkaloid proximate to their optimum values,and the activity of amylase positively proportioned to the price tier of the cigarette to be made,while the contents of nicotine,total nitrogen,starch and activity of polyphenol oxidase were on the contrary.
