. Brief introductionÂ
medium temperatureα-amylase
preparation is produced by submerged fermentation of Bacillus
subtills and extraction with modern technique. Â
2. Function and
characteristicsÂ
medium temperatureα-amylase
can hydrolyzeα*1,4
glycosidic bond of the starch. Starch molecule is randomly
hydrolyzed into short dextrin chain in different length and small
amount of low molecular weight sugars. Both amylose and amplopectin
can be randomly hydrolyzed, resulting in the rapid decrease of the
viscosity of starch solution. During the process, the starch is to
be liquefied, so the medium temperatureα-amylase
is also called liquefying enzyme.Â
3. Enzyme
activity Â
medium temperatureα-amylase
(Liquid) 2,**0μ/ml,Â
                                                                                                  3,**0μ/ml
                                                                              Â
 (Powder) 2,**0μ/g
1μ/ml
(1μ/g)
is defined as the amount of enzyme in 1ml( 1g ) enzyme solution to
liquefy 1g soluble starch per hour at pH6.0 and *0℃.Â
4.
Application conditionsÂ
Optimal pH: 6.0 -
6.5Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Effective
pH: 6.0 - 7.0
Optimal temperature: *0℃- *0℃                  Â
Effective temperature: *0℃- *0℃
It will lose activities badly when pH is below 5.0. When the
temperature is between *0 and *0℃, the reaction rate increases with the
rise of the temperature. Meanwhile the activity loss also
increases. It can be used in the liquefying process at temperature
up to *0℃. The increase in the concentration of
starch improves the stability of enzyme activity. Calcium ion can
improve the thermostabality of the enzyme.
5. Package and
storageÂ
1.Package: liquid products are packed with *5 kg non-toxic plastic
barrel or ***0kg IBC.
Powder products are packed with film bag ( 2 kg /bag) as inner
wrapper and carton as outside wrapper, and net  weight of
each carton is *0 kg .
2.Storage: 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 *5℃).    Stored at
*5℃ for six months or at 5℃ for one year, the enzyme activity is not
less than *0% of the labeled value.Â
6. Application
scopeÂ
medium temperatureα-amylase
is widely used in liquefaction process in the production of starch
sugar, alcohol, beer, monosodium glutamate and in other
fermentation industry, and the desizing of textile, printing and
dyeing. When this product is used in alcohol, citric acid,
fermentation industry and other food processing, the dosage and
application condition of the enzyme could be decided through
experiments according to its characteristics.Â
