- 活力:≥4000U/g
- 活力定义:在70℃,PH6.0条件下,1分钟液化1mg可溶性淀粉成为糊精所需要的酶量,即为1个酶活力单位
- 来源:黑曲霉
- 温度范围:最适作用温度在90℃以上,95-97℃液化迅速,100℃仍保持相当的活力,在喷射液化时,瞬间温度可达105-110℃
- PH范围:有效PH范围在5.5~8.0,最适PH范围在6.0-6.5
- 钙离子浓度对酶活力的影响:本品对Ca2+要求不高,在50-70ppm Ca2+已足够
- 性状(以下信息仅供参考):黄褐色或类白色粉末。在较高温度条件下,此酶能迅速水解淀粉分子的精制α-1,4葡萄糖苷键,将淀粉分子从内部任意切断成长短不一的短键糊精和少量的低聚糖,从而使淀粉浆的粘度迅速下降。液化时间延长,还会产生少量的葡萄糖和麦芽糖
- 储存条件: 2-8°C
