摘　　要：烟叶中以细胞壁物质存在的碳水化合物在燃吸时产生不良影响。在一定条件下向烟叶中施加一定量的纤维素酶和果胶酶 ,使部分细胞壁物质降解为水溶性糖 ,烟质得到改善。纤维素酶和果胶酶最佳用量均为每克烟叶 30u酶量 (活力 )。最佳作用条件为 :烟叶水分 2 5 % ,作用温度 5 0℃ ,作用时间 4h ,且在真空条件下可使细胞壁物质降解更有效 ,可降解烟叶中细胞壁物质 10 %左右 。The ways of enzymatic degradation of cell wall substances in tobacco was studied. Under certain circumstances, a certain quantity of cellulase and pectase is added to tobacco in order to degrade cell wall substances into water-soluble sugar. It has been determined that the best proportion of cellulase and pectase are 30u/g. The best conditions are :moisture content 25%, time of action on enzyme 4h, temperature 50℃.It will be more effective in vacuum condition.in this condition,the substances of cell wall in degraded to fiuecured tobacco can be decreased to 10%.
