壳聚糖是甲壳素的脱乙酰化产物,具有安全无毒、抗菌、吸湿透气、吸附性强、成纤性好以及良好的化学反应活性和生物活性等特点。蚕蛹壳中含有丰富的甲壳素,是提取壳聚糖的优质原料。介绍了蚕蛹壳聚糖的制备工艺技术,着重讨论了蚕蛹原料预处理、脱无机盐、脱蛋白质、脱色、脱乙酰等工艺流程采用的技术方法;简述了蚕蛹壳聚糖在农业、纺织、食品加工、医用材料、环保、生物工程等领域的应用状况;分析了蚕蛹壳聚糖产业化生产存在的问题,提出了解决办法。
Chitosan is deacetylated product of chitin, which is safe, non-toxic, antibacterial, hygroscopic and breathable, strong adsorption, good fiber-forming and good chemical reactivity and biological activity. Silkworm pupa shell is rich in chitin, chitosan is the high quality raw materials. The preparation technology of silkworm chrysalis chitosan was introduced. The technical methods of silkworm pupa chitosan pretreatment, de-mineralization, deproteinization, decoloration, deacetylation and other technological processes were mainly discussed. Food processing, medical materials, environmental protection, bioengineering and other fields. The problems existing in the industrialized production of silkworm chrysalis are analyzed and solutions are proposed.
