Working Mechanism

The enzyme hydrolyzes the α-1,4-glucosidic linkages of gelatinized starch randomly to soluble dextrins, reducing the high viscosity of the starch slurry.

Application Guide

• In brewing of beer and alcohol: add the enzyme in the rate of 6.0L/t raw material (base on 2000 u/ml ). Keep at 80-90°C for 30 minutes.
• In the starch sugar: monosodium glutamate and the liquefaction of fermentation industry Starch slurry is 16-18Be adjust pH to 6.2-6.4. Add 0.2 calcium chloride (calculate on weight of raw material ) . dosage of alpha amylase as 6.0-8.0L/t raw material ( base on 2000 u/ml). Blend well and heat to 85-90°C for 30 minutes.
• In textile desizing: Add the enzyme in the rate of 0. 2% (owf) base on 2000 u/ml. keep at 50-80°C for 20-40 minutes.
• In feed industry: the recommended dosage is 0.02-0.04 kg/t raw material . For the best performance, can blended with pectianse, β-Glucanase and xylanase etc.
• In juice processing: the commended dosage is 0.02-0.1 L/t or iginal juice slurry (base on 2000 u/ml) about temperature 45°C for 60-120 minutes.
• In steamed bread and bread fermentation series products: can blended with pectianse, cellulase and protease etc.
• Others: Rate of use is generally 2-4 L/t dry basis, Ca 2 + concentration 150ppm.
