Acidic Protease, Form : powder, Packaging Type : tawny

We are offering acidic protease.

Description summary
ttx acid protease is a carboxyl protease extract from aspergillus niger by a solid fermentation technique and refined by an advanced post-treatment technique. It can hydrolyze the peptide bond of protein on the acidic condition and release the amino acid or polypeptide.
Industrial grade acid protease is mainly used in alcohol and fermentation, leather processing, textile, food and feed industry. It is ideal for use in the industries that utilize corn, broomcorn, rye and other high starch content ingredients. With the aid of acid protease, alcohol production becomes more efficient, increasing 0.3-0.5% alcohol and reducing energy consuming.
Definition of content (gbt 23527-2009)
one unit (u) of acidic protease activity is defined as the amount of enzyme which liberates 1 μg tyrosine per minute from substrate casein at ph 3.0 and 40 ℃. (gbt 23527-2009)

application (detaied dosage should be depending on ingredients and other considerations)
1. In the alcohol fermentation,adding this enzyme can validly hydrolyze the protein in material, damage the cytoderm structure between granular material, be in favor of the function of sugar enzyme, increase the available carbon of the material which can improve the rate of coming out of of the material.
Recommended dosage: 50-150gt (100000 ug)
batch fermentation of alcohol: add acid protease after filling 13 of the ingredients.
Continuous fermentation: add acid protease at the first fermentation tank of per batch.
2. In the processing wool fiber and dying of textile industry, it can enhance the strength of fabrics, non felt. Recommended dosage 100000 ug acid protease is 0.6-2.0% (owf), ph 3.0-3.5, temperature 40-50℃, bath ratio 1:20-40, time 60-90 min.
3. In the fermentation of vinegar and distillate spirits of food field, it can promote the growth and cultivation of microzyme, improve fermentation speed.
Recommended dosage: 150-200gt (100000 ug)
