Our amylase is an enzyme that catalyses the hydrolysis of starch into sugars. The α-amylases (EC 126.96.36.199 ) could act at random locations along the starch chain, and breaks down long-chain carbohydrates, ultimately yielding maltotriose and maltose from amylose, or maltose, glucose and "limit dextrin" from amylopectin. Because it can act anywhere on the substrate, α-amylase tends to be faster-acting than β-amylase.
Our amylases are used in bread-making and to break down complex sugars, such as starch (found in flour), into simple sugars. Yeast then feeds on these simple sugars and converts it into the products of alcohol and CO2. This imparts flavour and causes the bread to rise. Modern bread-making techniques have included amylases into bread improver, thereby making the process faster and more practical for commercial use.
Our alpha amylases are important in brewing beer and liquor made from sugars derived from starch. In beer and some liquors, the sugars present at the beginning of fermentation have been produced by "mashing" grains. Our amylase products could accelerate the mashing process, and significantly improve the ratio of malted grain to convert the barley's starch into sugars.
Our amylases is often listed as an ingredient on commercially package milled flour.
This thermal stable alpha-amylase product was produced by Bacillus licheniformis strain, which fermented in submerged medium.
-- Our alpha-amylase product has excellent thermal stability. In the process of the liquefaction of starch, at pH 5.0—7.0, the enzyme could keep active at 93 oCto 95 oC
-- By using our alpha-amylase product, the liquefaction of starch could be finished very soon, and the conversion ratio could be higher than 95%, thus it cold a fast and definite separation of the protein in starch. Thus could simplified the following process and improve the efficiency.
The activity of the thermal stable alpha amylase was 40,000 U/g to 250, 000 U/g.
(*High activity product is available upon request of our customers.)
【DEFINITION OF ENZYME ACTITIY】
Reducing sugar method: At a pH of 6. 0 and temperature of 70 oC, the amount of enzyme needed to hydrolyze 1 mg starch in 1 min, name as U/g.
In the fermentation processs, 0. 3 kg enzyme (20,000U/mL) was recommend to added into 1,000 kg mash, and the temperature could be set as 100 ± 5 oC,kept for about 100 min, and then saccharification
