Chitosan is an important biomedical material, and its degree of deacetylation is a main parameter of its biodegradation. 壳聚糖是一种重要的生物医用材料，脱乙酰度是影响其生物降解性能的重要因素。
The result showed that, immersion under pressurized condition could prepare chitosan with a higher degree of deacetylation and higher molecular weight. 结果表明，压力浸渍法可得到更高脱乙酰度和更高分子量的壳聚糖产品。
