Neutral protease is an endo-proteinase extract from bacillus subtilis1.398 by a liquid submerged fermentation technique and refined by an advanced post-treatment technique. It can rapidly hydrolyze the macromolecular protein into peptone, peptides, and finally into amino acids, applicable to leather depilation softening,silk degumming, toothpaste, soap, detergent, baking,dairy and other industries.
1. Supplement the deficiency of serine endo-proteinase for animal.
2. Increase protein digestibility in animal feed and reduce the dosage of protein in feed formula.
3. Decrease the difference of feedstuff from different area and stabilize production performance.
4. Protect the environment and lessen pollution from nitrogen.
Definition of content
One unit (U) of neutral protease activity is defined as the amount of enzyme which liberates 1 μg tyrosine per minute from substrate casein at PH 7.5 and 30ºC
Application(Detaied dosage should be depending on ingredients and other considerations)
1. Leather processing: Depilation is complete, no obvious damage, pores is smoothening and light. Recommended dosage: 150-300 u/g for leather depilation, 8-15u/g for leather softening, e.g the dosage of 100000 U/g neutral protease is 0.15-0.30% for leather deplilation, 0.008-0.015% for leather soften.
2. Silk degumming: pretreatment→ dehydration→acid treating (Protease18-24u/ml, soap 0.75%, 40ºC, 30-60min, pH7.0)→ dehydration→degumming→ washing→ dehydration→ fluffing→ drying→ fluffing.
3. In the textile industry, wool treated with neutral protease feel soft and smooth, no contractility, the tensile force is higher than normal method. It is also suitable for silk degumming and silk refining.
