Application Guide:
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.
Application Notice:
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 .
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 .
Safety Usage:
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.
