High-Temperature
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:
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.

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

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.
