摘要: 本实验研究了由Alcalase碱性蛋白酶、Flavourzyme风味蛋白酶、Neutrase中性蛋白酶、无锡2709碱性蛋白酶、无锡精制中性蛋白酶等蛋白酶水解棉籽蛋白的水解度及水解液抗氧化活性的大小。结果表明,Alcalase碱性蛋白酶水解能力最大,水解液清除自由基的能力也最大,实际生产中为了去除多肽的苦味物质,应先用Alcalase碱性蛋白酶水解,再用Flavourzyme风味酶作用。

Abstract: Several proteolytic enzymes(such as Alcalase, Neutrase, Flavourzyme, etc) were studied. The results showed that Alcalase had best hydrolyze ability and anti-oxidation in all enzymes. Double-enzyme of alcalase and flavourzyme can not increase the DH, but can remove the bitter of peptide. In actually production, Flavourzyme should be used by step to hydrolyze cottonseed protein after reacted with alcalase for removing the bitter of peptide.

Key words: cottonseed peptide, proteases, degree of hydrolysis, anti-oxidation
