Amylases (Ethanol Enzyme),China Bevenovo price supplier

Instructions

Amylases (Ethanol Enzyme) is a high temperature stable bacterial amylase enzyme preparation derived from Bacillus licheniformis. It has good tolerance to high temperature and can be used in the manufacture of starch sugar (glucose, malt syrup, dextrins, oligosaccharides) and alcohol, brewery etc.

Specifications

Product Name: Hi-Temperature Resistance Amylases (Ethanol Enzyme)

Model No. Amzyme-HT

Enzyme activity 20,000 U/g

Higher enzyme activity will be supplied based on the customer's requirements

It is workable between the PH range of 5.5-8.0 and the product retains its activity up to 100°C centigrade, however, the most suitable working conditions is at PH 6.0-6.5 and at the temperature of 95-97 centigrade, A co-factor such as Ca ²⁺ at a concentration of 50-70 ppm is required for optimal activity.

Unit Defintion

One unit of Alpha-amylases enzyme activity (U) is defined as the the amount of enzyme which needed to hydrolyze 1 mg of starch in one minute at PH 6.0 and temperature of 70 centigrade

Basic Principle    

Alpha-amylases enzyme (endo-a-1,4-glucan 4-glucanohydrolase) are endo-acting enzymes which

specifically cleave  a-1,4 D-glucosidic linkages in gelatinized starch randomly to produce dextrins of varying lengths, thereby reducing the high viscosity of the starch slurry. Oligosaccharides, glucose and Maltose are also produced.

Functions And Doses

Alpha-amylases enzyme is used in the manufacture of starch sugar of gourmet powder. With a starch syrup concentration of 16-17B and PH of 6.0-6.5, the enzyme need to add at the rate of 0.6 liter/ton (when using the 20,000 u/mL product). The mixture is stirred and the temperature is raised and kept at 95-100°C for 100 minutes or 60-120 minutes at 95°C if steam (105°C) injection method is used.

In brewing of beer, add Alpha-amylases enzyme in one batch at the rate of 0.3 liter/ton when using the 20,000 u/mL product. The temperature of the mixture is raised and kept at 95-97°C for 30 minutes.

In the manufacture of alcohol, Alpha-amylases enzyme is added at the rate of 0.3 liter/ton (when using the 20,000 u/mL product) at PH 6.5-7.0. The temperature is raised and kept at 100±5 °C for 100 minutes.

Packing, Shelf Life And Storage
