产品介绍
氨基肽酶是由米曲霉(Aspergillus oryzae)经深层发酵提炼、精制而成的食品级酶制剂。广泛应用于肉制品加工、植物蛋白加工、复合氨基酸液的生产中。 原理 氨基肽酶属于外肽酶,是一种从多肽链N末端顺序逐个水解氨基酸的酶。因其可以切除苦味肽上的疏水氨基酸,所以有脱苦作用。 产品特性 1.温度范围:有效温度范围35℃-85℃,最适温度范围60℃-65℃。 2.pH值范围:有效pH范围3.0-9.5,最适pH值范围6.0-6.5。 3.金属离子对酶活性的影响:Co2+对酶有较强的激活作用;Mn2+、Mg2+对酶活力影响不大;Ca2+、Cu2+、Zn2+、Ni2+有抑制作用。 产品标准:执行中华人民共和国国家标准GB1886.174-2016。 应用方法 1.在动植物蛋白水解时,首先调节物料浓度10%-40%,调节 pH6.0- 6.5,反应温度50℃-55℃ , 加酶量0.2-1.0kg/t原料,水解6h-24h,蛋白质水解率20%-40%。 2.为了提高蛋白质水解率,一般选择内肽酶(如中性蛋白酶)与该酶配合使用。 3.如因工艺限制,浓度、温度、pH不在上述范围,则可以通过加酶量调节。一般来说,浓度越高、温度和pH偏离有效范围越多,则加酶量越高,反之加量越低。 储存 本品为生物活性物质,高温、强酸、强碱会引起酶失活。在运输和储存过程中避免暴晒和雨淋。仓库应保持清洁、阴凉和干燥。
