摘　　要：以微波干燥的黄粉虫为原料,研究了索氏抽提法提取油脂、碱法脱除蛋白质、酸浸法去除灰分、次氯酸钠脱色和浓碱法脱乙酰基制备甲壳素和壳聚糖的工艺.系统分析了不同工艺条件对甲壳素的残留蛋白质含量、灰分含量,壳聚糖的脱乙酰度、粘度的影响,得出制备甲壳素和壳聚糖的最佳工艺条件,以期为工业生产提供依据.With the powder of microwave dried Tenebrio molitor as starting material, the extraction technology of chitin and chitosan was studied by adopting soxlet extraction method to extract oil, using the acid leaching method to remove ash, sodium hydroxide solution to remove protein, sodium hypochlorite to decolorize samples, and NaOH solution to deacetylate the product. The effects of different extraction conditions on residual protein content, ash content, degree of deacetylation and viscosity of chitin and chitosan were systematically analyzed. The optimum conditions were obtained.
