Product DescriptionHK-540L is a food-grade alpha amylase produced from selected strains of Bacillus licheniformis through submerged fermentation and refining extraction processes. It is an endoamylase that can randomly hydrolyze the alpha-D-1,4 glucosidic bonds of starch, glycogen and its degradation products at high temperatures and low pH conditions , to reduce the viscosity of the starch and to produce soluble dextrins and oligosaccharides.With its superior heat-stability and acidic resistance, HK-540L is applied to the liquefaction of starch materials in the starch sugar industry and fermentation industry, such as the production of citric acid and amino acid. Benefits for the starhc sugar production > Outstanding performance without adding calcium under normal conditions;> Superior stability under low pH, which decreases the chemicals for pH adjustment;> The short-chain dextrin molecules have an even size, which helps to increase the glucose content in the downstream saccharification process;> Decrease the formation of unwanted colorful substances and non-fermentable sugars;> Capable of liquefying various starch substitutes, such as tapioca, corn, wheat, and rice.SpecificationDeclared Enzyme:Alpha-AmylaseSystematic Name:EC 3.2.1.1, 1,4-α-D-glucan glucanohydrolaseActivity:200,000 U/ml (minimum)Appearance:Sepia brown liquidProduct pH:5.0～7.0Specific gravity:1.15～1.25 g/mlEFFECT OF pHHK-540L can work at pH 4.5～6.5,with its optimal pH range 4.8～5.8. EFFECT OF TEMPERATUREFor interval liquefaction, HK-540L works at its optimal temperatures above 90°C. It can liquefy starch quickly at 95～97°C and remain active at 100°C. For consecutive spray liquefaction, HK-540L demonstrates its exceptional heat stability at high temperatures and keeps on rapid and complete liquefaction at 105～115°C for 5～7 minutes.Packing & DeliveryThe typical packaging is 30kg food-grade HDPE canisters, or 1125kg IBC totes. Customized packaging is available upon request.The typical shelf-life is 18 months if provided being stored at 0～25°C in its original packaging, sealed and unopened, and protected from direct sunlight. This enzymes has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, and thus should be avoided.Safe Handling of EnzymesInhalation of enzyme dust and mists should be avoided. In case of contact with skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.
