High temperature resistant α-amylase SNbase-HT
Product Brief
High temperature resistant α -Amylase SNbase HT is a food grade high temperature resistant starch hydrolase, which is produced by fermentation, extraction and refining of Bacillus licheniformis and Bacillus asparticus. The enzyme is an endonuclease that randomly hydrolyzes α-D-1,4 glycosidic bonds, reducing the viscosity of starch, resulting in soluble dextrins and oligosaccharides.
Product Features
This product fully complies with the hygienic requirements stipulated in the national standard GB 8276-2006 for food-grade enzyme preparations.
◆Vitality: 20,000u/ml
◆Appearance: Brown liquid (a small amount of agglomerates are allowed)
◆PH: 5.0-6.5
◆Specific gravity: 1.00-1.20
◆Microbiological indicators

◆Heavy metal index
Heavy metals (in Pbit), mg/kg ≤30
Arsenic (as Asi), mg/kg ≤3
◆The effect of pH value
The effective pH range of high temperature α-amylase is 4.5-7.5, and the optimum pH range is 6.0-6.5.
◆The influence of temperature
High temperature resistant α-amylase has a wide temperature range, between 50°C-100"C. As the temperature increases, the liquefaction rate increases and remains quite vigorous at 100°C.
◆Influence of Ca2+
This product does not require high calcium ions. Usually, starch and production water already contain a certain amount of calcium ions, so adding 30-50ppm is enough.
Efficacy
Because the product shows high activity in the temperature range of 50-70°C, it is especially suitable for the liquefaction of starch with low gelatinization temperature.
Conditions
◆In the process of beer brewing, after the auxiliary materials and water are mixed evenly, the enzyme is added in 0.20-0.40 liters per ton of auxiliary materials. The gelatinization and liquefaction were carried out at a heating rate of about 1 degree per minute, and the temperature was kept at 90-95°C for about 30 minutes. After passing the iodine test, the liquefaction was terminated. For starch with lower gelatinization temperature (such as corn, etc.), it is recommended to keep at 70°C for 10-20 minutes. Then continue to heat up.
◆Adding this enzyme in saccharification can shorten the saccharification time, reduce the iodine value of the wort, and improve the starch yield. The recommended addition amount is 0.001-0.01%. In the production of alcohol, after the raw materials are crushed, sieved, and mixed with water, the enzyme is added at about 0.30 liters per ton of raw materials. After stirring, the enzyme is pumped into the cooking pot or continuously Cooking heater. During cooking, the temperature can be controlled at 100±5°C. Time 100 minutes, saccharification after cooling. Other fermentation industries use methods similar to alcohol production.
Add amount
The recommended dosage of high temperature resistant α-amylase is 0.20-0.40L/T, and it is recommended to carry out the optimization test of dosage first.
The optimum amount of enzyme should be determined according to the specific conditions of the plant.
Add method
Add a certain amount of warm water into the gelatinization pot, put in the starchy raw materials (auxiliaries) while stirring, then add the enzyme preparation, stir evenly, and start to heat up.
Product Certification
◆1S09001:2008 Quality Management System Certification
◆HACCP food safety certification
Product Packaging Specifications
Heat resistant amylase is packaged in 25kg plastic drums.
Storage and Shelf Life
High temperature-resistant amylase should be stored away from light, sealed and stored at low temperature. The shelf life is 12 months when stored at 4-10°C.
Product Safety Instructions
The enzyme solution should be avoided from contact with the mucous membranes of the eyes, nose and mouth. If it is accidentally inhaled or splashed into the eyes, immediately rinse with water for more than 15 minutes.
