1. Characteristics: Type of Action: Thermostable Alpha Amylase is an endonuclease which can immediately hydrolyze amylum, soluble dextrin and low polysaccharide. It also can immediately reduce the viscocity of gelling starch, then gelling starch are hydrolyzed into dextrin, dextrose and maltose. The effects of PH on amylase activity and amylase stability of this product: When PH ranges from 5.0 to 10.0, it is stable. Its favorable PH ranges from 5.0 to 8.0. Its most favorable PH ranges from 5.5 to 7.0. Its favorable temperature is above 90. When it is continuously spouted and liquefied, the temperature could range from 105. Appearance: brown liquid Amylase activity: 20,000u/mL to 35,000u/mL Capability (g/ml):1.15---1.2 Amylase livability: 90% of amylase can live more than 3 months. 2. Definition and Recommended Quantity At 70°C and PH6.0, the quantity of amylase used to liquefy 1 mg soluble amylum into dextrin is regarded as 1 amylase activity unit. Of 1T amylum, it is better to use 200-400ml Thermostable Alpha Amylase. 3. Packing It is packed in toxin free plastic drum. 1100KG/drum or 25KG/drum. We can also pack according to clients requirement.
