摘要
以地产龙虾壳为原料,探讨微波辐射法快速制备壳聚糖的工艺。着重对微波辐射法制备壳聚糖的加热时间、碱液浓度等对壳聚糖脱乙酰度、粘度等性质的影响进行研究,并和酸碱法制备壳聚糖的方法进行比较。结果表明:微波辐射法制备龙虾壳聚糖的适宜工艺为:碱液浓度45%;微波加热15 min;微波功率280 W;具高效性。用该法制备的龙虾壳聚糖的红外光谱和X射线衍射谱图与市售生化级壳聚糖的图谱基本一致,且工艺设备简单,操作方便,具有较强的推广性。
Taking the lobster hull as material this paper discusses the craft of quickly make chitosan by microwave radiation method. It emphasizes study on the heating time,lye concentration etc. influence to the deacetylate degree, viscosity etc. in the method of make chitosan by microwave radiation method and compares with sour alkaline method. The result indicates:the feat craft of make lobster chitosan by microwave radiation method is :45% of alkali liquor concentration;15 mins of microwave heats;microwave power 280 Ws;have high efficiency. The IR spectrum and XRD are basic identical compared with chitosan of biochemical reagent. The craft equipments are simple and have the stronger expansion.
