摘要
通过半湿研磨法制备出堆积密度>0.50g/mL的壳聚糖,其堆积密度提高60%～90%。此方法操作简单、无污染、成本低廉,同时处理后的壳聚糖不仅没有失去其碱性多糖的特点,而且溶解范围加宽、溶解速度加快、溶液黏度提高若干倍和味道香甜,是一种较理想的医药、食品添加剂。
Chitosan was processed by the method of half wet grinding with tap density ）0.50 g/ mL and increasing 60%- 90%0. The preparation process was convential, sanitary and economical. The chitosan processed didn＇t lose it＇s basic polysaccharose property. Furthermore, many properties were significantly improved, such as solubility, dissolution speed, solution viscosity and odor. Solution viscosity increased many times. The high tap density chitosan will be a kind of ideal additive for food and medicine.
