【摘要】 花生蛋白经过碱性蛋白酶ALCALASE、复合蛋白酶PROTAMEX水解得到活性肽溶液.通过单因素试验及正交试验得到各个因素的优化组合,并进一步研究活性肽的抗氧化特性.结果表明,ALCALASE对花生蛋白的水解能力优于PROTAMEX;花生肽具有较强的抗氧化性及有效清除羟自由基的能力,在本试验范围内随水解度的增加而提高.更多还原

【Abstract】 Enzymatic hydrolysis of peanut protein was investigated by two proteases(alcalase and protamex).Through single factors and orthogonal experiment,the optimal conditions were obtained and the antioxygenic property of peanut peptides was studied.The data showed that the capability of hydrolysis of alcalase was higher than that of protamex;peanut peptides have obvious antioxygenic property and ability to clear HO· in effect and increased with a higher degree of hydrolysis.更多还原
