Compare with the big corporation Novozyme and Genencor in this line ,we have a large advantage over price in the conditions of same quality Email: greenyear2@163.com MSN:wintersunshine1987@hotmail.com Telephone:86-0510-85102755-605 High temperature α-amylase (Thermostable alfa-amylase) • Brief introduction to the products Green Year Brand High temperature α-amylase preparation is produced by submerged fermentation of Bacillus lichenifirmis and modern extraction technique. • Function and characteristics Greenyear brand High temperature α-amylase can randomly hydrolyze α-1.4 glycosidic bonds of starchy materials and theirs degradation products to produce the soluble dextrin and oligosaccharides, resulting in the quick decrease of the viscosity of starch solution. The excessive hydrolysis will produce a small amount of glucose and maltose. • Enzyme activity High temperature α-amylase (general type): 20,000 μ/ml High temperature α-amylase (high efficient type): 30,000 μ/ml High temperature α-amylase (concentrated type): 60,000 μ/ml Definition of the enzyme activity: The amount of enzyme in 1 ml enzyme solution required to liquefy 1 mg soluble starch per minute at the condition of pH 6.0 and 70℃ is defined as one unit of enzyme activity. • Application conditions Optimal pH range: 5.5 to 7.0; Effective pH range: 5.0 to 8.0 Optimal temperature range: 90 to 95℃; Effective temperature range: 90℃ to 100℃ In spray-liquefy technology, when the instantaneous temperature increases to the range of 105℃ to 110℃, this enzyme still can hydrolyze starch effectively. This enzyme has very good heat stability. End, It is recommended to add 50 to 100 mg/kg of calcium ion in the hydrolysis of starch. • Package and storage 1. Liquid type of this product is packed with 25 kg non-toxic plastic barrel. 2. With the best efforts to avoid insolation and high temperature during the transportation and storage. Keep the environment clean and cool, and it is better to store at low temperature (environmental temperature below 25℃). When stored at 25℃ for six months or at 5℃ for one year, the enzyme activity is not less than 90% of the labeled value. If a small amount of deposits appears, shake up before use and it has the same effect. • Application scope Greenyear brand thermostrable α-amylase has very good heat durability. It can be widely used in industry of starch, alcohol, beer, monosodium glutamate, citric acid, brewing, glucose, maltose and textile, etc. |
