Alkaline protease JP-20 is a powder form preparation produced from Bacillus licheniformis through submerged fermentation, extraction and refining process. JP-20 can catalyze the hydrolysis of proteins under alkaline conditions (pH 9-12). It is suitable for leather hair removal and silk degumming.
Pale brown powder
EFFECT OF Temperature
The effective temperature range for JP-20 is from 20 to 65℃, and the optimal temperature ranges from 40 to 50℃.
EFFECT OF PH
JP-20 has an effective pH from 9 to 12, and the optimal pH ranges from 10 to 11.
APPLICATIONS AND BENEFITS
The use of JP-20 in leather processing enables the following benefits:
Shortened processing cycle
Improved quality of finished products
Increased leather yields
Reduced production costs
Note: The above recommended dosage is based on raw material mass for leather processing.
The use of JP-20 in silk degumming enables the following benefits:
Effectively removal of silk sericin without damage to the fibroin
Enable silk fleeciness and lustrous, soft and smooth surface
Note: The above recommended dosage rate is based on the mass of raw material for silk degumming.
JP-20 is packaged in 25kg cardboard drums or kraft paper bags. Customized packaging is available upon request.
This enzyme has been formulated for optimal stability. Typical shelf-life is six months provided it is stored below 25°C (77°F) in its original packaging, sealed and unopened, protected from the sunlight. Its shelf-life will be eighteen months if it is stored properly at 0～10°C(32～50°F). Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement.
SAFETY & ENZYME HANDLING
Inhalation of enzyme dust and mists should be avoided. In case of contact with skins or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.
