红螯螯虾壳制备壳聚糖的研究 |
| 范国枝; 韦一良(武汉工业学院生物与化学工程系; 湖北武汉) |
| 摘 要：以红螯螯虾壳为原料提取甲壳素,得到白色片状产品,收率为18%。甲壳素通过脱乙酰化制备壳聚糖,脱乙酰度可达83%。考察了浸酸时间、浸酸温度和NaOH浓度对产品质量的影响。结果表明,采用红螯螯虾壳制备壳聚糖是可行的。 |

| Abstract：The chitin was distilled from the shell of cherax quadricarinatus with 18% yield.The chitosan was prepared from chitin by deacetylating and the degree of deacetylation was 83%. The effect of the soaking acid, temperature and the NaOH concentration on the product quality were studied. The results show that it is possible to prepare chitosan from the sheet of cherax quadricarinatus. |
