2. Definition of enzyme activity: The amount of enzyme needed to hydrolyze 1mg of starch in one hour at pH6.0, 60 ℃.
Usage and reference dosage
(The following dosage is an example of 2000 u/g, other specification can be converted according to the enzyme activity)
1. In manufacturing process of beer brewing and alcohol: Recommended dosage is 3.0L/Ton of raw materials, liquefying at 80-90°C and keep for 30 min.
2. In manufacturing process of starch sugar, Maltose, monosodium glutamate and other fermentation industry: Recommended dosage is 0.2% Calcium chloride(based on the weight of raw materials) and add amylase 3.0-4.0L/Ton of raw materials and liquefying at 80-90°C and keep for 30 min.
3. Textile de-sizing: 0.2%(o.w.f.) and keep at 50-80°C for 20-40 min. (It is suitable for the materials which can not withsand high temperature such as silk, chemical fiber, woven fabric of cotton, wool and etc.)
4. In feed industry: this enzyme functions as improving digestion, adjusting immunity and improving feed utilization. Recommend dosage is 0.02-0.04kg/Ton of complete formula feed. Generally, it is used with pectinase, β-Glucanase and Cellualse for better performance. β-Glucanase and Cellulase for better performance.
5. In manufacturing process of juice: this amylase can improve the juice transparency and avoid turbidity. Recommend dosage: 0.02-0.1 L/Ton of juice raw materials and keep at 45°C for 60-120 min. Generally, it is used with Pectinase and Cellulase for better performance.
6. In manufacturing process of steamed bread, bread and other flour products: this amylase can improve the product quality and lengthen the shelf life. Recommended dosage is 0.05-0.1kg/Ton of raw materials.
7. Other Industries: Recommended dosage is 2-4 L/Ton of dry basis and the concentration of calcium ion is 150ppm.
