Haimeng study Industrial Co., Ltd. supply α- amylase enzyme

Description Haimeng study Industrial Co., Ltd. of quality manufacturers, α- amylase phone manufacturers, α- amylase CAS number, α- amylase, Shanghai α- amylase latest offer, α- amylase price, α - the role of amylase, α- amylase factory distributor, α- amylase manufacturers latest offer, the amount of α- amylase, α- amylase formula, α- amylase molecular weight. English: a-Amylase vitality: 10000 CAS: 9000-90-2. Overview: Temperature α- amylase using Bacillus subtilis (Bacillus Subtilis) by submerged fermentation extracted from. Widely used in alcohol, beer, monosodium glutamate, starch, sugar, liquefaction and fermentation industry of textile, printing and dyeing desizing and so on. Principle: the hydrolysis of starch molecules in the α-1.4 glucoside bond, any short cut to varying small amounts of short-chain dextrins and low molecular weight carbohydrates, amylose and amylopectin, are no rules form decomposition, so that the viscosity of the starch burnt fell rapidly, the "liquefaction" effect, it is also called amylase. Features: 1, thermal stability: stable at 60οC below the optimum temperature 60 -70οC, suitable for up to 90οC liquefaction process. 2, PH stability: relatively stable at PH6.0-7.0, optimum PH6.0, PH5.0 less severe deactivation. 3, calcium ion concentration on enzyme activity: calcium ions on the stability of the enzyme activity has been improved effect, no calcium, complete loss of enzyme activity. Applications: 1, applied starch concentration in the caramel, enzymatic MSG is 16-17B, PH adjusted to 6.2-6.4, and 0.2% of calcium chloride (calculated by weight of raw materials), and then added amylase starch (the raw material with an enzyme per gram of 6-8 units), thoroughly mixed, heated to 85 -90οC, liquefaction about 30 minutes. 2, used in beer production using rice flour first time through a 40 mesh sieve over corn as materials, in burnt pot of mashing after adding amylase enzyme dosage in six units / g feed or so, 85 -90οC liquefaction 30 minutes. 3, used in textile desizing using purified liquid amylase as desizing agent for not high temperature silk, chemical fiber, cotton, wool, desizing process, the amount of enzyme in 0.2% (2000u / g) or so, 50 -80οC 20-40 minutes in a water bath. 4, other industrial control in general the amount of enzyme per gram of starch of 6-8 units of enzyme activity, calcium ion concentration 150ppm. Storage: The strains of biologically active substances, sunlight, temperature, humidity, to cause enzyme inactivation. Should prevent direct sunlight, should be placed in a cool, dry place. Α- amylase is a fungal α- amylase produced by microbial fermentation of Aspergillus. Different bacterial α- amylase is fungal α- amylase optimum temperature is about 55 ℃, exceed 60 ℃ start deactivation; product of hydrolysis of starch which is mainly maltose and some of the high content of oligosaccharides and a small amount glucose. The bacterial α- amylase optimum temperature (temperature α- amylase 70 ~ 80 ℃, high temperature α- amylase is 95 ~ 105 ℃), the main product of starch hydrolysis is burnt fine. Thus, bacterial α- amylase only used in the fermentation industry, and fungal α- amylase is widely used in starch syrup, oligosaccharides, beer, baked goods, flour products such as the production, with a very broad market prospects. Fungal α- amylase Overview: fungal α - amylase is an enzyme extracted from koji Val (Aspergillus oryzal var) fermentation, refined from a food-grade α - amylase. The enzyme of endo-amylases, rapidly hydrolyzed linear and branched internal aqueous starch α -1.4 glycosidic bond, generating a large number of small amounts of maltose and maltotriose, glucose and other oligosaccharides. This enzyme is mainly used for the production of high maltose syrup can also be used in beer industry. Enzyme application methods: fungal α - amylase is mainly used in high maltose syrup production. Best of saccharification conditions depend on PH, temperature, substrate concentration and enzyme dosage. Manufacturers each application to determine the best process conditions on their own terms, generally recommended to use as follows: PH 5.0-5.5, the reaction temperature is 50 -60 οC, enzyme dosage 0.15 -0.30kg / ton of dry starch, saccharification time 12-24 hours .
