| 摘 要： | 采用酸碱法从马尾松毛虫蛹中制备壳聚糖,结果表明:马尾松毛虫蛹依次经盐酸脱矿物质、氢氧化钠脱有机物质、双氧水脱色处理后获得白色片状固体物甲壳素,其水分含量为3.32%,灰分为0.99%,脱乙酰度为92.54%,粘度为18.3MPa·s;由甲壳素制备壳聚糖的条件为NaOH浓度50%,处理时间5h,处理温度80℃;由甲壳素获得壳聚糖产品的产率为79.21%。

| Abstract: | The preparation of chitosan from pupa of Dendrolimus punctatus Walker was studied with the acid-alkali method. The results showed that the chitin from D punctatus was obtained based on the removal of minerals and organic materials with HCl and NaOH,respectively. For the preparation of chitosan,the condition was the follows: alkali concentration was 50 %,treatment time was 5 h and treatment temperature was 80 ℃. The obtained chitosan under the condition was white sheet solid. The water and ash content of the chitosan product was 3.32 % and 0.99 %,respectively. The degree of deacetylation of the product was 92.54 %,viscosity was 18.3 MPa·s and the yield was 79.21 %. |
