Detailed Description

Heat-stable Alpha-Amylase HT-800 Low pH Tolerate Food-Grade Liquefaction Enzyme For Starch Sugar Robust Activity , Superior Thermo-stability , Adapted to Low pH Conditions Decrease Viscosity of Starches Quickly EffectiveLiquefaction ofSarches from Tapioca/ Cassava, Corn, Wheat, Rice, etc. Eliminate Undesirable ColoredSubstances & Non-fermentable Sugars - - - - Certificate: | # Halal # Kosher | Grade: | # Food-Grade | - - - - DESCRIPTION # HT-800 is a robust Heat-stableAlpha-Amylase(EC 3.2.1.1, 1,4--D-glucan glucanohydrolase)produced from selected strains of Bacillus licheniformisthroughsubmerged fermentation and refining extraction processes. As an endoamylase, HT-800 can quickly decrease the viscosity of gelatinous starch solutions by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1,4 glucosidic bonds to produce soluble dextrins and oligosaccharides. # HT-800 is a robust Heat-stable Alpha-Amylase adapted to low pH conditions for the production of starch sugar. PRODUCT CHARACTERISTICS - - - - Declared Enzyme | Alpha-Amylase | Systematic Name | 1,4--D-glucan glucanohydrolase | Activity | 80,000 U/ml | Appearance | Sepia brown | Physical Form | Liquid | Product pH | 5.57.0 | Specific Gravity | 1.15 to 1.25 g/ml | - - - - EFFECT OF PH &TEMPERATURE ON ACTIVITY: # HT-800 can work at pH ranging from 5.07.0 with its optimal pH being 5.46.0. # The exact pH optimum depends on the actual processing conditions, including temperature, substrate concentration and reaction time. # For interval liquefaction, the optimum temperature of HT-800 is above 90C. It liquefies starch substrates promptly at 95 97C and maintains highly active at 100C. # For consecutive liquefaction, HT-800 demonstrates exceptional thermal stability at temperature range from 105 to 110C and keeps on liquefying efficiently for 5 to 7 minutes. CONCENTRATION OF CALCIUM # The presence of calcium increases the thermal stability of HT-800. # This enzyme requires a very low calcium concentration of 20 to 50 ppm (dry solids basis) to ensure its enzyme stability. INHIBITORS # Copper, titanium, and cobalt ions are moderate inhibitors for HT-800. # Aluminum, lead and zinc ions act as strong inhibitors. USAGE GUIDELINES # For industrial application of one-time spray liquefaction, first prepare 30 to 35% w/w starch slurry, adjust pH 5.4 to 6.0, then add this product at a dosage rate of 0.10 to 0.35 kg/TDS. # Liquefy at 105 to 107C for 5 to 7 minutes, flash cooling down to around 97C, keep on liquefying at temperature above 95C for 90 to 120 minutes so as to reach required DE value. # In case the starch content is above 35%, recommended dosage rate is from 0.35 to 0.4kg/TDS. # Exact dosage rate depends on the actual situation such as starch substrate, liquefaction equipment, processing conditions, etc. # To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. PACKAGING, STORAGE AND SHELF-LIFE: - - - - Package: | # 25kg, 30kg plastic drums # 1125kg IBC totes | Shelf-life & Storage: | # Typical shelf-life is six months if it is stored below 25C in it soriginal packaging, sealed and unopened, protected from the sunlight. # Its shelf-life will be eighteen-months if this product is being store properly at 010C. # Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided. | - - - -
