Medium temperature amylase is an endo-starch hydrolase extracted by deep fermentation culture of selected Bacillus subtilis, followed by microfiltration, ultrafiltration, and vacuum freeze-drying technology. It is widely used in the industries of starch sugar, alcohol, brewing, monosodium glutamate, glucose, organic acid and antimicrobial agent.
Medium temperature amylase can hydrolyze soluble starch, straight chain starch, glycogen, etc. in medium temperature (60-85℃) environment with high efficiency. By randomly cutting the a-1,4 glucosidic bond in the sugar chain, starch and glycogen can be decomposed into dextrin and oligosaccharide monosaccharide with different chain lengths, which can rapidly reduce the viscosity of the solution.
It is easily soluble in water, and the aqueous solution is clarified light yellow liquid, insoluble in ethanol or ether.
Main components: medium temperature α-amylase, glucose Product specification: 10,000-20,000 U/g (can be customized) Product properties; light brown powder Storage: room temperature dry and protected from light Shelf life: 12 months
1. Fixed powder processing
Medium temperature amylase can be applied in the production of sugar with starch as raw material, such as: caramel, maltodextrin, maltose, etc.
2. Brewing and fermentation industry
Medium temperature amylase can also be used in wine brewing, soy sauce, vinegar brewing and other industries to break down starch into monosaccharides available to yeast, shorten the brewing cycle, while effectively reducing viscosity and improving filtration speed.
3. Baking industry
Medium-temperature amylase can be used in flour improvement, releasing glucose by decomposing starch, promoting yeast reproduction, increasing fermentation speed and reducing the amount of sugar, which is widely used in bread, cake, cookie and other baking processing.
4. Grain processing
With people’s pursuit of balanced nutrition, adding cereals to milk, cereals and baby food is popular. Medium-temperature amylase can be applied to pretreatment of cereal raw materials to improve solubility and facilitate subsequent product processing while increasing nutritional value.
5. Health supplement
In modern society, overeating has become a common phenomenon, causing a great burden to the digestion of the stomach and intestines. Amylase can be used in the processing of digestion-promoting drugs to ease the digestive burden powder enzymes can also be applied to dietary supplements and nutritional fortification of various plant ingredients to break down the starch of plants into small molecules of polysaccharides, making their nutritional value higher.
在其最简单的形式中,中温α-淀粉酶由与 1) α-直链淀粉(一种淀粉)的混合物组成,它可以从植物或动物产品中制备; 2)少量中温酶(酶A),和3)少量水。这可以在室温下储存在密封袋中长达 6 个月。 With proper storage conditions and proper selection of plant materials, medium temperature α-Amylase appears to function well in both winemaking and vinegar brewing.
如果你想获得真正的技术知识,阅读酶的结构和功能很有用(参见维基百科上的相关文章),但正如我上面所说,如果你只是想快速了解两种类型的组成,那么这篇文章由 Dr. David Katz 相当不错:http://drkatzlab.org/enzyme/alpha_amino_acid_hydrolysis/alpha_amine_hydrolysis
