Α-淀粉酶 (CAS No.9001-19-8)
- 物化性质
- 外观为黄褐色粉末或浅褐色非粘性液体，粉末易溶于水，具有酶特有的气味，无潮解结块现象，液体允许有少量凝聚物。能随机水解淀粉、糖原及其降解物内部的α-1,4葡萄糖苷键，使淀粉糊粘度迅速下降。最适作用温度55℃左右，超过60℃开始失活；pH6.0-7.0较为稳定，最适pH6.0，pH5.0以下失活较重。钙离子对酶活力稳定性有提高作用，无钙离子时酶活力完全丧失。

English description（英文原文，共 1650 字符）
Product Name:Fungal α-Amylase
English Name:Fungal α-Amylase
CAS No.:9001-19-8
Aliases:Fungal alpha-amylase
Physical Properties:Appearance is yellowish-brown powder or light brown non-viscous liquid. The powder is readily soluble in water, has the characteristic odor of the enzyme, shows no deliquescence or caking, and the liquid may contain a small amount of coagulum. It randomly hydrolyzes α-1,4-glucosidic bonds in starch, glycogen, and their degradation products, rapidly reducing the viscosity of starch paste. The optimum temperature is approximately 55°C; inactivation begins above 60°C. The enzyme is stable at pH 6.0-7.0, with an optimum pH of 6.0, and loses activity significantly below pH 5.0. Calcium ions enhance the stability of enzyme activity; in the absence of calcium ions, enzyme activity is completely lost.
Uses:Used as an enzyme preparation, widely applied in the production of starch syrup, oligosaccharides, beer, baked goods, and flour products, as well as in the fermentation industry for maltose, glucose, alcohol, and liquor, and in textile desizing processes.
Technical Specifications:
Appearance is yellowish-brown powder or light brown non-viscous liquid; the powder is readily soluble in water and has the characteristic odor of the enzyme without deliquescence or caking.
The optimum temperature is approximately 55°C; inactivation starts above 60°C.
The optimum pH is 6.0 with a stable pH range of 6.0-7.0; significant inactivation occurs below pH 5.0.
Calcium ions increase the stability of enzyme activity; without calcium ions, enzyme activity is completely lost.
Packaging specification: 25 kg/drum.
