壳低聚糖具有优越的生理活性，但其在长期的保存过程中容易变质。为了便于长期保存，将其制备成壳低聚糖硫酸盐。用高效液相色谱测定其分子量，用酸碱滴定法确定壳低聚糖硫酸盐的组成。以壳低聚糖为参照，研究壳低聚糖硫酸盐的吸湿、保湿性及其在不同时间、温度、pH值的稳定性。结果表明：样品中主要成分是壳低聚糖硫酸盐；壳低聚糖硫酸盐的保湿能力比壳低聚糖强，在不同时间、温度、pH值的条件下比壳低聚糖稳定。

Low-molecular-weight chitosan （LCS） have superior physiological activities, but it is easy for the LCS to brown. In order to store the LCS for a long time, the LCS sulfate was prepared and the content of LCS sulfate was determined by acid-base titration. Moisture-absorption, moisture-retention capacity and stability were studied. The LCS sulfate was the main component of the sample, and had better moisture-retention capacity than LCS, and was more stable than LCS.
