多糖在自然界中蕴藏丰富,种类繁多,应用广泛。多糖的研究一直受到人们的关注。本文对目前多糖研究中存在的问题,分子修饰的概念和目的,辐照技术的原理、多糖辐照分子修饰的方法进行了介绍。同时对辐照技术在壳聚糖、淀粉、卡拉胶、海藻酸钠、纤维素等多糖分子修饰中的实际应用进行了综述。
Polysaccharides have attracted tremendous attention due to the abundance with a variety of species and quantities in nature and extensive application in wide-range fields. In this paper, current problems related to polysaccharide research, concepts and purposes for polysaccharide modification, mechanisms and methods for polysaccharide molecular modification by radiation technology are reviewed. Meanwhile, practical applications of radiation technology in molecular modification of polysaccharides including chitosan, starch, carrageenan, sodium alginate and cellulose are also discussed.
