中文摘要: 利用中性蛋白酶、碱性蛋白酶、风味蛋白酶、胃蛋白酶和复合蛋白酶分别水解谷朊粉,发现复合蛋白酶水解谷 朊粉水解度较大,水解后分子量较小,且后续蛋白回收率较大,因此选用复合蛋白酶作为后续谷朊粉改性用酶。
中文关键词: 谷朊粉  溶解度  蛋白酶  筛选
Abstract:Using the neutral protease, alkaline protease, flavor protease, pepsin and protemax protease to hy- drolyze the wheat gluten separately, the following results showed: the the hydrolysis degree of wheat gluten hy- drolyzed by protemax was bigger than hydrolyzed by others, the the molecular weight after hydrolyzed was smaller, and the subsequent protein recovery rate was bigger. Therefore the protemax was choosed as the sub- sequent modified enzyme for wheat gluten.
