Quick Details Other Names: Glucoamylase Usage: Textile Auxiliary Agents Purity: other Appearance: brown liquid PH value: 5-7 CAS No.: 9000-90-2 Type: carbon black EINECS No.: 232-565-6 Classification: Chemical Auxiliary Agent MF: other Chemical component: bacterial amylase Packaging Detail: In 130kg drum. Selling Units: Single item Single package size: 10X8X7 cm Single gross weight: 1.5 KG Mid-Temperature Alpha-Amylase DHK188P Product Description The product is obtained by deep fermentation of Bacillus Subtilis. It is widely used in manufacture of starch sugar and alcohol, brewery, textile, dye & printing, papermaking, feed industry etc. 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. Property: 1. Temperature: Effective Temperature Range : 35-90 ℃, Optimum 60-70 ℃. 2. pH: Effective Range 4.5-8.0, Optimum pH Range 5.2-6.2 . 3. Effect of Metal Ion on Enzyme activity : Ca 2 + can improve the stability of the enzyme , Enzyme activity will completely lost without Ca 2 + , Mn2+ and Mg2+ also have the obvious improvement onactivity besides Ca 2 + . Specification: 1. Liquid type: Appearance: light brown liquid .2,000 u/ml ,3,000u/ml,4,000u/ml Solid powder type: Appearance: Yellow powder. 2,000, 3,000, 4,000u/g and 50,000u/g. food grade is white powder, We have the specification from 1000 to 10000 u/g (activity vary against thousand unit ) according to the customer’s requirement. Liquid Enzyme Ph( 25℃): 5.5-7.0, Specific Gravity: 1.10-1.25g/ml; Solid Enzyme Soundness (0.4 mm mesh screen ): ≥80%. 2. Unit activity definition : The amount of enzyme needed to hydrolyze 1mg of starch in one hour at pH6.0, 60 ℃. It is u/g(u/ml). Standard : QB1805.1-93. Application Guide: 1. 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 ℃ for 30 minutes. 2.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℃ for 30 minutes . 3. In textile desizing, add the enzyme in the rate of 0.2%(owf) base on 2000 u/ml , keep at 50-80 ℃ for 20-40 minutes. 4. In feed industry, this enzyme can improve the digest function, adjust immunity, increase the utilization of grain energy .The recommended dosage is 0.02-0.04kg/t raw material . For the best performance , It often blend with pectianse, β-glucanase and xylanase etc. 5. In juice processing , this enzyme can improve transparence and avoid turbid. The commended dosage is 0.02-0.1L/t original juice slurry (base on 2000 u/ml) about temperature 45 ℃ for 60-120 minutes. 6. In steamed bread and bread fermentation series products,food grade Mid-Temperature Alpha Amylase can improve texture of finished product and extend the shelf life. It often blend with pectianse, cellulase and protease etc. 7. Others: Rate of use is generally 2-4 L/t dry basis, Ca 2 + concentration 150ppm. Package and Storage Plastic drum is used for liquid type: 25kg/drum Plastic weave bag is used for solid type: 20kg/bag. Further package customizable. This product is organic biochemical substance, high temperature, strong acid & strong alkaline will cause inactivation of enzyme. So, avoid exposure to sunlight when being transported. Solid enzyme should avoid direct sunlight and rain. It should be kept in clean, cool and dry place, or you need to increase its dosage.
