微波辅助酶水解明胶制备多肽酰胺表面活性剂
Preparation of Peptide Amide Surfactant through Microwave Assisted Enzymatic Hydrolysis of Gelatin
摘要
Abstract
Gelatin hydrolysate was prepared through microwave assisted digestion of gelatin using papaya protease.Peptide amide surfactant was synthesized with diethanol amine,gelatin hydrolysate and fatty acid.Raw materials ratio,fatty acid, reaction temperature and reaction time that may affect the properties of the resultant products were studied.The decontami-nation effect and foaming height were investigated.The optimum synthetic conditions were obtained as follows:the hydroly-sis temperature was 55,℃,microwave power was 280,W,and the hydrolysis rate of microwave was 8 times higher thanthat for common enzyme hydrolysis.The best ratio ofm(diethanolamine):m(gelatin hydrolysate):m(lauric acid)is 1:4:1, 145,℃ was selected as the reaction temperature,and the reaction time was 5,h.Under these conditions,PAS has the best surface properties,so it can be applied to the development of skin washing cleaner without water.关键词
