1. In manufacture of alcohol for grain fermentation , The recommended dosage is 10-15 units /gram raw material .It is also decided according to raw material and specific technics .
2. In manufacture of feedstuff and food processing , The recommended dosage is 5-10 units /gram raw material.It is also decided according to the specific conditions of customer .
3. In manufacture of soy sauce, add the enzyme for 25 units, In the fermentation of solid distilled spirit , add the enzyme for 20 units.
1.when the Acid Protease for solid type is used ,they should dissolve
in the water with the proportion of 1:20.at the temperature of 30-40 oC .
2.when the Acid Protease is used in fermentation industry , the speed of fermentation is quickened, The rising temperature is rapid for fermentation.It should strictly controll the temperature which is not more than 40 oC.
It should avoid the inhalation of mist or dust of enzyme .It should wash with water for at least 15 minutes in case of contact with hands and eyes.
Package and Storage:
Plastic weave bag is used in solid type, 20kg/bag,Plastic drum is used in liquid type,25kg/drum.Further package customizable.This product is organic biochemical substance,sunlight & high temperature will cause inactivation of enzyme. So, It should be kept in ventilated and dry place below the temperature of 25oC, It can be longly preserved at the temperature of 5oC.
