酶在烟叶调制、陈化和贮存期间起着非常重要的作用。近年来关于如何利用外加酶改善烟叶内在品质已经成为烟草行业的热点话题。利用酶制剂可以降解烟叶中过量的淀粉、蛋白质、细胞壁物质和果胶质，增加香气和改善质量品质。另外，酶制剂在烟草添加剂、烟草香料、烟草薄片中的应用，酶制剂和微生物配合使用的研究也在增加。

Enzyme plays an important role in tobacco curing, aging and storing management. How to use the enzyme to improve smoking quality has become a hot topic in tobacco industry in recent years. Enzyme can degrade the excessive starch, protein, cell wall substances and the pectin in tobacco leaves, enhance the fragrances and improve the quality of the tobacco. Besides, the applications of enzymes on the tobacco additives, tobacco flavor and reconstituted tobacco production are reviewed and researches on the combination of enzyme and microorganism used in tobacco industry are also introduced here.
