普通壳聚糖不溶解于水，只能溶解在部分稀的无机酸或有机酸中，在很大程度上限制了其应用。水溶性壳聚糖通过特殊工艺精制而成，改善了普通壳聚糖的溶解性能，保持了壳聚糖的高分子特性，使用更加方便，应用范围更加广泛。

ordinary chitosan is insoluble in water and only soluble in some diluted organic acid and inorganic acid, which limits its application. water soluble chitosan is refined with special techniques, improving the soluble performance of ordinary chitosan and keeping the macromolecule performance. thus, the application is more convenient and the scope is wider.
