复合蛋白酶催化制备生理活性鹿肽及鹿肽产品的应用
摘要：
本发明涉及一种应用复合蛋白酶催化的方法水解鹿肉制备具有生理活性的鹿肽产品，以及该鹿肽产品在提高机体免疫力、增强抗疲劳能力及耐缺氧能力等方面的应用。该鹿肽产品是以处理过的过80目标准筛的肉浆为原料，在恒温反应罐中加热至48－52℃，用NaOH溶液调节pH值到6.8－7.2，搅拌下加入中性蛋白酶、木瓜蛋白酶或胰蛋白酶，待蛋白质水解度达28～33％后再加入风味蛋白酶，继续用标准的2MNaOH溶液控制反应进程，使蛋白质水解度达34～42％；然后将酶解液升温至114－116℃，维持10－15分钟后迅速将温度降低到室温，经固液分离、浓缩及干燥后得淡黄色到黄色的粉末或者颗粒鹿肽产品。
摘要（英）：

This invention relates to preparation of deer peptide with biological activity by composite protease catalysis and its uses in human immunity, fatigue resistance and hypoxia tolerance. Products are obtained by heating deer meat paste as raw material, which is screened with 80 mesh, to 48-52 deg.C, regulating pH 6.8-7.2 with NaOH solution, stirring and adding neutral protease, papoid or trypsin, then adding fragrant protease after protein hydrolysis to 28-33%, controlling reaction with standard 2M NaOH to make protein hydrolysis to 34 -42%, heating enzymolysed liquid to 114-116 deg.C for 10-15 minutes, sharply cooling to atmosphere, solid-liquid separating, concentrating, and drying to obtain yellow powder or granular products of deer peptide.
