Applications (Adjustable according to experiment results)

1.For leather processing, it can shorten processing time, simplify working procedure and improve product quality. Recommended dosage of 100000 U/g protease is 0.02-0.1%, 20-25℃, 12-20h for retting process; 0.05-0.2%, 35-38℃, 3-6h for leather soften; 0.1-0.3%, 20-35℃, 12-20h for leather depilation.

2.For silk degumming, it may make silk lint-free and fluffy without damaging silk. After pretreatment, the recommended dosage of 100000 U/g protease is 0.8-2.4% pH9-11, 40-50℃, 30-60min.

3.For chondroitin production, it can improve yield and purity, after extracting alkali, recommended dosage of 100000 U/g protease is 0.2-0.6%, pH8-10, 40-50℃, 4-8h.

4.For heparin sodium production, it can increase uniformity of molecule and purity, after salt solution, recommended dosage of 100000 U/g protease is 2-4g per small intestine,pH9-11, 45-60℃, 4-6h.

5. For detergent production, it can remove the stains of sweat, blood, protein and milk, and get a unique detergent effect. Recommended dosage is 0.2-1.0%
