中文摘要：

淀粉作为一种可再生的天然资源,已成为重要的工业原料。由于原淀粉的许多固有性质（冷水不溶性,糊液在酸、热、剪切作用下不稳定）限定了淀粉的工业应用,人们根据淀粉的结构和理化性质开发了淀粉的变性技术,即变性淀粉。随着变性淀粉诸多优良性质的显现,其在国内外食品行业的应用也越来越广泛。本文介绍了变性淀粉的制备方法及应用领域,并对变性淀粉的发展做了展望。

英文摘要：

Starch has become a kind of important industrial raw material as renewable natural resources.Because many inherent qualities of the original starch（ infusibility in cold water,instability of paste liquid in acid,heat and shearing action） limit its industrial application. So people developed modified technology according to the starch structure and physical and chemical properties,named modified starch. With many good properties of the modified starch,its application in food industry is becoming more and more widely at home and abroad. This paper introduces preparation methods of modified starch,domain,and prospects the development of modified starch.
