The degradation of starch during curing has great effect on tobacco quality. The changes of microstructure and properties of tobacco leaves during the mature period and curing process, their effects on starch degradation and the relationship with the quality were discussed. The future research focus and methods on the microstructure and properties of tobacco starch were also discussed.% 烘烤过程中烤烟淀粉的降解对烟叶品质有重要的影响。笔者系统地介绍了成熟与烘烤过程中烤烟淀粉的微观结构、特性的动态变化，并分析了烤烟淀粉微观结构、特性与其降解性能和烟叶品质的关系，对以后烤烟淀粉微观结构、特性的研究方向和方法进行了探讨。
