| 摘 要： | 以海藻酸钠为底物,在实验室自制的褐藻胶裂解酶的催化下,通过控制酶解时间,得到平均聚合度(DP)分别为3,4,6的3种褐藻胶寡糖DP3,DP4,DP6。通过干燥器控制湿度的方法对产物进行吸湿和保湿性能测试,并和化妆品常用保湿剂丙三醇、聚乙二醇600(PEG600)及原料海藻酸钠进行比较。结果表明,在0～64 h内,在相对湿度(RH)为43%的环境中的吸湿率大小为:DP3>丙三醇>DP4>DP6>PEG600>海藻酸钠;在RH为81%的环境中的吸湿率大小为:丙三醇>DP3>DP4>DP6>PEG600>海藻酸钠;在硅胶环境中保湿能力大小为:DP3>DP4>DP6>丙三醇>PEG600>海藻酸钠。64 h时DP3在RH为43%和81%环境下的吸湿率分别为66.4%和108.9%,在硅胶环境中的保湿率为46.1%。DP3表现出优良的吸湿和保湿性能,是一种很有开发潜力的天然保湿剂。

| Abstract: | Three algin oligosaccharides with different degree of polymerization(hereinafter refers to as DP),DP3,DP4 and DP6 respectively were prepared through enzymolysis of algin and algin-lyase(prepared by the author from Acinetobacter junii in the laboratory) as the catalyst.The different DP was obtained by controlling of enzymolysis reaction time.Hygroscopic and moisturizing performance of the products was tested by method adopting dryer with humidity control.The test results were compared with that obtained from... |
