摘要： 为降低烤后烟叶中的纤维素含量，改善纤维素对烟叶品质的不良影响，研究了纤维素酶的不同用量对烟叶纤维素含量、化学成分以及中性致香物质的影响。结果表明1）纤维素含量随外加酶量增加而减少，总糖、还原糖含量随外加酶量增加而增加；2）纤维素酶用量为40ｕ/g时，可以使烟叶中的中性致香物质总量提高25.52%。

Abstract: In order to reduce the content of cellulose in tobacco leaves after flue-curing and change the adverse effects of cellulose on tobacco leaves,the influences of the different amount of cellulase on tobacco cellulose content, chemical components and neutral aroma components was studied. The results showed that the content of cellulose was decreasing and the content of total sugar and reducing sugar was increasing as increasing of the quantity of additional amylase.When the amount of cellulase was 40ｕ/g,the amount of neutral aroma components of tobacco could increase 25.52%.
