摘　　要：淀粉作为仅次于纤维素的可再生性资源,具有价廉易得、可降解性和易转变成淀粉衍生物等特点。长期以来世界各国都十分重视淀粉资源的开发利用研究,尤其通过各种方法对淀粉的改性一直是科技工作者和生产厂商的研究热点。本文综述了国内外糖酶对淀粉生物法改性的种类、作用方式和各种生物改性淀粉(抗消化淀粉、微孔淀粉、分支环糊精、缓慢消化淀粉、淀粉膜、酯化淀粉等)制备的基本研究状况,并对其发展前景进行了展望。As one of the abundant renewable natural resource which is inferior to cellulose, starch is readily available and inexpensive. It also can be degraded easily and turned into useful ramification by biochemical method. Every country attaches much importance to exploiture of starch resource for a long time. Especially many investigators and manufacturer have done works on natural starch denaturalization which is becoming the hot spot through physical, chemical and biological methods. In this paper, the process in studies on modified starch based on biological methods by carbohydrase is summarized. The kinds of carbohydrase, action patterns and preparations of the bio-modified starches （resistant starch, microporous starch, branched cyclodextrin, slowly digestible starch, starch film, starch esterification etc.） are introduced. The long-term potential development of bio-modified starch is prospected.
