HEAT STABLE ALPHA-AMYLASE(HSAA)
BACTERIAL ALPHA°™AMYLASE(BAA)
HICH CONVERSION GLUCOAMYLASE
BACTERIAL ALPHA°™AMYLASE(BAA)
Introduction:
°°°° The °įSynder°Ī bacterial alpha-amylase with its 90s high technique introduced from U.S.A, is obtained by the controlled fermentation of Bacillus subtilis filtration, concentration and polishment. The product are widely used in starch, glucose, maltose,dextrin, oligosaccharides, alcohol, MSG, textile, pharmaceutical and etc. The product has the following advantages: Fast liquefaction of starch, easy filtration, Less dosage, simple process, high quality, good recovery, cost cutting and saving energy and facilities.
Principle:
°°°° The enzyme is an endoamylase which can randomly hydrolyze the interior alpha-1, 4-glucosidic linkage of starch, yielding soluble dextrins and oligosaccharides. Consequently the viscosity of gelatinous starch solutions is rapidly reduced, Prolonged hydrolysis with the enzyme results in the formation of small quantity of glucose and maltose.
Stability and Activity°°Effect of temperature:
The enzyme has exceptional heat stability and can be effectively used in batch and continual system of starch liquefaction.
Optimum temperature 85°ś
Effect of PH:
°°°° Optimum PH range 6.5°°°°Effective PH range 7.0 to 6.0
Activators:
°°°° Calcium ions make great contribution to the stability of the enzyme. For liquefaction of starch slurries the addition of 100 to 150ppm calcium is recommended.
Specification
°°°° 1000u/ml, 1500u/ml, 2000u/ml.
Package:
°°°° Packaged in 25 plastic drum£¨ 1000KG IBC.
Definition of activity:
°°°° One unit of enzyme activity is that amount of enzyme which will dextrinize 1.0g of soluble starch in one minute under the following conditions: Temp 60°ś; PH 6.0
Applications reference
Alcohol industry:
°°°° In distilling process raw material should be milled and pass through 1.5 mm sieve Mix well with water in the ratio of 1 to 3.5 to 4, PH 6.0 -7.0. In high temperature distilling process, 0.5L of BAA is added into one ton of materials. Heat in the container at 90°ś. In low temperature distilling process, 1L enzyme is added into one ton of materials. Heat in the container at 80-85°ś. In steam jet process, the temperature at outlet may reach 88-90°ś and maintain at 85-88°ś,2L enzyme is added into one ton of materials.
MSG, Maltose and Glucose industry:
°°°° Mix raw materials with water adjust PH value and then 2.5L of enzyme is added into one ton of materials. In batch liquefaction raise the temperature up to 80-85°ś rapidly, maintain for 30 minutes. In steam jet process, the temperature at outlet may reach 88-90°ś and maintain at 85°ś for 30 minutes.
Shipping and Storage:
°°°° 1.The product contain organic and liosubstance, inactivation may occur under the extreme light and heat. prevent the Product from Sunlight and rain, and keep the storage room clean, cold and dry. When the product is stored at a temperature of 25°ś, the declared activity is maintained for at least three months.
°°°° 2.Turbidity which may occur in the enzyme preparation has no influence on the volumetric activity or the product. Please stir it before use the product in this case.
