beta-amylase

الوصف

Specifiction**- activity:**0,**0 u/g minimal
                     appearance:  clear brown liquid
                     solubility:   completely miscible in water
                     specific gravity:  1.*5～1.*5g/ml

Application conditions**-optimal pH: 5.0 – 6.8
                                 optimal temperature: *5℃ - *0℃
The enzyme activity will increase with the rise of temperature.Metal ion Ca2+, Mg2+ (concentration 0.*5mM—0.*8mM) can activate the enzyme. The enzyme stability will be better if with starch & Ca2+ ion together. But Metal ion Hg2+,Fe3+ and oxidant will restrain the enzyme activity.

Function**-1. High Maltose Syrups.All kinds of starch material can be used to produce High Maltose Syrups by SD.BA**0. Liquefy starch by alpha-amylase, then saccharify it for long time by SD.BA**0 to get Maltose Syrups with concentration *5%**2%, or High Maltose Syrups with concentration over *0%. saccharify it by SD.BA**0 and pullulanase enzyme together to get the Super High Maltose Syrups with concentration over *0%.
               2. Beer.(A)Additional enzyme method. If the barley malt is in poor quality with low enzyme activity, add some alpha-amylase to liquefy the substrate completely, then add SD.BA**0 at saccharification process.(B)Part substitute method. If total raw material quantity (barley malt & starch) is definite, reduce the cost by reducing the barley malt share. The starch share will be *5% to *0% according to the different barley malt quality. Increase alpha-amylase dosage along with starch share increasing, and add SD.BA**0 during saccharification. 
              3. Starch syrup.In traditional starch syrup producing process, the barley malt is used for saccharification. Now SD.BA**0 can replace the barley malt, which can reduce the cost and simplify the process.
After raw material being marinated, crushed and mixed around with water, add alpha-amylase to liquefy it. Cool it to*0℃ after raw material being liquefied completely, then add SD.BA**0 to saccharify it till complete saccharification, filtration and concentration.

Package****5 kg non-toxic plastic barrel.

Storage**-with the best efforts to avoid insolation and high temperature during the transportation and storage. Keep the environment dry and cool. Highlight, high temperature, alkali and strong acid will make the enzyme lose activity.
