Neutral protease
One.Function and using range
This product is a kind of solid enzyme which is extracted from Bacillus subtilis which is deeply fermented.It can hydrolyze the macromolecular protease to amino acid,etc.Meanwhile,it is used to remove the fur,soften the skin,remove glue of the silk,reclaim film and medicine,etc.
Two.Define of enzyme activity
In the case of 30 centi degree and PH:7.5,the speed,using 1g solid enzyme powder to hydrolyze casein can produce 1ug tyrosine in one min,is defined as enzyme activity(u/g).
Three.Product specification and package
This product is powder.content of water is below 6 percent.internal package:2kg,and external package:20 or 30 kg.enzyme activity:50000u/g.
Four.Product standard
It accords with business standard of QB1805-93 of people republic of China.
Five.Using condition
The best temperature:35-45 centi grade The best PH:6.5-7.5.
Six.Adding amount and using methods
1. Used in removing fui of feather,removing fui with enzyme(35-4235-42℃，pH7.5，20-25u/ml)-wash-dip acid.
2. Usd in reclaiming file.45 centi grade,PH7.0-7.5,20-23u/g
3. Used in removing glue of silk:advanced disolve-remove water-acid disolve(protease 18-24u/g,soap 0.75%,48-50℃30-60minutes,PH7-8)-remove water-pull skin-wash-remove water-shake-bake-shake.
4. Used in medicine:it can be used to treat chronic bronchitis,cough,etc.
5. Used in feed:it can be mainly used together with amylase,acid protease,cellulose enzyme,sugar enzyme,etc.It can be expansively used in the feed of pig,fish and other animals.After this enzyme is put into the feed,you can well control of the temperature,moisture,PH and working time in order to dissolve the material in the function of this enzyme.If you feed animals in a small scale,you can add the enzyme directly,and stir sufficiently,and then feed animals.Generally the proper amount is 0.1-1.0 percent compared to the feed.
Seven.Storage and transportation
This product is a activated substance,which should be put in cool,dry place,and avoided strong sunshine,heat,moisture.In the transportation,you should avoid strong shining and raining them.In the event of 25 centi degree,enzyme activity can be well kept over 85 percent in six months.
