Alpha-amylases
1.
INTRODUCTION:
Starch, a high polymeric
carbohydrate is a mixture of two polysaccharide, amylose and
amylopectin. Starchy substrates like corn starch need to be acted
upon by high temperature stable alpha-amylases to produce shorter
length dextrins while glucoamylases are used mainly in the
production of glucose syrup, high fructose syrups and starch
hydrolysis for alcohol production.
High  Alpha-amylases is a high
temperature stable bacterial amylase 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, glutamate, textile, dye & printing, paper making
etc.
2. WORKING
MECHANISM:Â
Alpha-amylases
(endo-a*1,*-glucan *-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.
3. PRODUCT
PROPERTIES:
 HighAlpha-amylasesprovides
maximal benefit at pH 6.**6.5 and at the temperature of
****7℃ (******7°F). The product has
a pH range of 5.**8.0 and the product retains its activity up to
**0℃. A co-factor such as Ca2+ at a
concentration of ****0 ppm is required for optimal
activity.
4.Unit
definition:
 The amount of enzyme
needed to hydrolyze 1 mg of starch in one minute at pH 6.0 at the
reaction temperature of *0℃.
5.APPLICATION
GUIDE:
 HighAlpha-amylases
is used in the manufacture of starch sugar of gourmet powder. With
a starch syrup concentration of ****7B and pH of 6.**6.5, the
enzyme is added at the rate of 0.6 liter/ton (when using the *0,**0
u/mL product). The mixture is stirred and the temperature is raised
and kept at *****0°C for **0 minutes or *****0 minutes at *5°C if
steam (**5°C) injection method is used.
l       In
brewing of beer, add HighAlpha-amylases in one batch
at the rate of 0.3 liter/ton when using the *0,**0 u/mL product.
The temperature of the mixture is raised and kept at ****7°C for *0
minutes.
l       In
the manufacture of alcohol,HighAlpha-amylasesis
added at the rate of 0.3 liter/ton (when using the *0,**0 u/mL
product) at pH 6.**7.0. The temperature is raised and kept at **0±5
°C for **0 minutes.
6.PACKAGING:
HighAlpha-amylases
liquid
preparation is packaged in *5 kg/plastic drum.
HighAlpha-amylasessolid
preparation is packaged in box or plastic lined bags.
Alternative packaging is
available upon the request of our valued customers.
7 STORAGE
CONDITIONS:
Store in a cool, dry place
and away from direct sunlight. HighAlpha-amylases maintains its
activity for considerably longer time when stored at lower
temperatures (below *5°C). The product should
Store in a cool, dry place
and away from direct sunlight. HighAlpha-amylases maintains its
activity for considerably longer time when stored at lower
temperatures (below *5°C). The product should not be
frozen.
8.ATTENTIONS:
HighAlpha-amylases is non-toxic
and biodegradable. However, unnecessary contact with the product
should be avoided. Long term exposure to protein based products
such as HighAlpha-amylases may sensitize
certain individuals to the product. Wash hands with warm soapy
water after handling. Keep out of reach of children.
