Three.Define of enzyme activity
In the condition of 30 degrees,pH7.5,one gram enzyme powder decomposed casein in one minute to produce 1μg tyrosine,which is defined as one activity unit .it is showed by u/g.
Four. using methods
1.Used in beer fermentation.When the quality of malt is poor or materials are too many,amino nitrogen in beer will be not enough,which will cause of bad propagation of jeast and raising the content of diacetyl.If you add this protease,it can incease the content of Alpha-amino nitrogen which can provide enough nutrition for the jeast’s growth.
2.Decomposing animal protein.Using this protease can decrease viscosity of fish,meat,etc and promote protein to be decomposed to amino acid.
3.Decomposing plant protein.this neutral protease can be used in production of soy milk,instant soy powder.
4.Used in feed: It can be extensively used in the feed of pig,fish and other animals. Generally the proper amount is 0.1-1.0 percent compared to the weight of feed.
Six.Package and Storage
1kg per aluminium foil bag,20kg per paper box.
This product is an activated substance,which should be put in cool,dry place.Enzyme activity can be well kept over 85 percent in six months in 25 degrees.
