Three.Enzyem activity define
In the condition of 37 centi grade,PH5.5,one activity unit is defined as the needed enzyme amout which it decomposes Beta-hyskon which the concentration is 4mg/ml for 1 micromole reducing sugar every minute.
Four.Using methods
In beer production,You should add it when the malt start to sugar and the suitable quantity is 0.1-0.5‰.It can improve obviously the filtering rate.
In the feed,You can add it as per the production way.The general decommended amount is 0.05-0.2‰.It will be good for the animal growth.
Five.Package and Storage
1kg per aluminium foil bag. 20kg per paper box.
This enzyme should be stored in dry and cool place.The enzyme activity will not be less than the signed enzyme activity and can last 12 months if it can be stored below 10 centi grade;enzyem activity can be well kept six months in normal temperature.
