Study on optimum preparation procedure for oxidative degradation of k-carrageenan
摘要
Abstract
Objective:To optimize the preparative procedure for oxidative degradation of k-carrageenan.Methods: The optimum conditions of oxidative degradation for k - carrageenan was selected with the yield and the scavenging activities of DPPH radical and marked by orthogonal experimental design.ResultS: The optimize preparative procedure was as follows:the oxidative degradation for K-carrageenan was at temperature of 90℃, when K-carrageenan was dissolved adding with 20% hydrogen peroxide immediately,and then adjust the solution pH to 8, keeping it for 2h.The yield and the scavenging activities of DPPH radical were 75.94% and 95.78%. Conclusion:The optimum preparative procedure was reliablaThe yield and the scavenging activities of DPPH radical were high,It had high economy benefit.关键词
