【摘要】 以鳕鱼皮胶原蛋白肽和硫酸锌为原料,利用微波固相法合成肽锌螯合物。以微波时间、微波功率、胶原蛋白肽和硫酸锌质量比为自变量,肽锌螯合率为响应值,利用二次正交旋转组合试验和响应面分析法对合成条件进行优化。结果表明,最佳反应条件为:微波时间105 s,微波功率252 W,胶原蛋白肽和硫酸锌质量比3:1,在此条件下,合成的鳕鱼皮胶原蛋白肽锌螯合物的螯合率为29.34%,与模型的预测值29.33%接近。更多还原

【Abstract】 In this paper,the synthesis of cod-skin collagen peptide chelated zinc compound by microwave-assisted solid-state synthesis was investigated.Quadratic orthogonal rotation combination design and response surface methodology were applied the chelated conditions by taking microwave time(X1),microwave powder(X2)and collagen peptide and zinc sulfate mass ratio(X3) as independent variables,while taking the chelated percent as dependent variable in the experiment.The results showed that the optimal reaction conditions were microwave time 105 s,microwave power 252 W,collagen peptide and zinc sulfate mass ratio of 3:1.Under these conditions,the predicted and experimental values of chelate yields were 29.33% and 29.34%,respectively.更多还原
