摘　　要：壳聚糖具有降低血液中胆固醇、降低血压、抗感染、控制关节炎、抗癌等多种作用。作为天然的食品防腐剂,壳聚糖不仅对人体无害,还具有很多保健作用。普通分子量的壳聚糖水溶性很差,一般使用酸溶液来溶解。通过合成各种壳聚糖的衍生物不仅提高了壳聚糖的水溶性还增强了它们的抗菌活性,使壳聚糖作为一种天然优质食品防腐剂成为可能。Chitosan has many health functions such as decreasing blood cholesterol, lowering blood pressure, anti-infections, controlling arthritis, anti-cancer and so on. However, the water solubility of normal chitosan is very poor, which is usually dissolved with acid solution. Recently researchers found that synthesized chitosan derivatives not only can increase the water solubility of chitosan but also improve the antibacterial activity of chitosan, making it possible to use chitosan as a natural food preservativ...
