Product Details
酸性蛋白酶
一、           产品简介:
德美公司产品是采用现代生物技术生产的高科技产品。它是一种在酸性环境下(pH 2.5-4.0)催化蛋白酶水解的酶制剂,适用于酸性介质中水解动植物蛋白质。可用于毛皮软化,酒精发酵,啤酒、果酒澄清,动植物蛋白质水解营养液,羊毛染色,废胶片回收,饲料添加剂等等。本品在酸性条件下有利于皮纤维松散,且软化液可连续使用,是当前理想的毛皮软化酶制剂;在酒精发酵中,添加酸性蛋白酶,能有效水解原料中的蛋白质,破坏原料颗粒粒间细胞壁的结构,有利于糖化酶的作用,使原料中可利用碳源增加,从而可提高原料出酒率;另一方面,蛋白质的水解提高了醪液中α-氨基态氮的含量,促进酵母菌的生长与繁殖,提高发酵速度,从而缩短发酵周期和提高发酵设备的生产能力。
二、           产品特性:
1、   产品性状:固体剂型,黄褐色粉末。
2、   作用方式:作用于蛋白质中的肽键,主要生成物为小肽和氨基酸。
3、   热稳定性:pH2.0-4.0条件下,40℃以下比较稳定,超过50℃酶活损失严重,60℃以上很快失活。
4、   pH稳定性:2.0-4.0之间稳定,超过此范围,失活较严重。
5、   作用条件:作用温度范围40-50,最适作用温度45;作用pH范围2.5-5.5,最适作用pH3.0-3.5。
6、   金属离子对酶活力的影响:被钙、镁离子激活,被铜、汞、铅离子所抑制。
三、           规格(固体剂型合格品):
