摘　　要：[目的]采用碱液法对蝇蛆壳聚糖的制备技术进行研究,探索最佳工艺条件。[方法]以蝇蛆壳聚糖脱乙酰度及黏均分子量为评价指标,优化制备参数。[结果]由蝇蛆甲壳素制备壳聚糖的最佳工艺为:碱浓度60%、温度100℃、时间10h。[结论]在此工艺下,可制得高脱乙酰度、高黏度、色泽洁白的蝇蛆壳聚糖。[Objective] The research aimed to research the best technology of preparative technique of housefly maggot chitosan（HMC）.[Method] The preparation parameters were optimized through the deacetylation degree and viscosity average molecular weight of housefly maggot chitosan.[Result] The best technology of preparative technique was as follows：concentration of NaOH was 60%,temperature was 100 ℃ and time was 10 h.[Conclusion] Under this technology,the HMC with high degree of deaceytlation and hyperviscosity can be prepared.The color of the product was pure white.
