Acid Protease AP-100L

An acidic protease ideal for leather processing,

capable to destroy the scales on the surface of wool fibers,

prevent wool from felting and enable easy dyeing.

DESCRIPTION

• Acid Protease AP-100L is produced from Aspergillus niger through submerged fermentation and extraction and refining technique. It can catalyze protein hydrolysis under acidic condition (pH 2.5～4.0) thus is applicable to hydrolyze plant and animal proteins under acidic conditions, such as proteolysis of animal and plant.
•  
• AP-100L is suitable for the production of leather.

PRODUCT CHARACTERISTICS

EFFECT OF PH

• AP-100L is stable with pH from 2.5 to 4.0. It will be inactivated quickly at pH below 2.5 or above 4.0. The optimal pH is 3.0 at the temperature of 40°C.

EFFECT OF TEMPERATURE

• Effective temperature is from 30 to 50ºC at pH around 3.0; Optimal temperature is 40ºC. It is stable below 40ºC, unstable above 50ºC and inactivated quickly above 60ºC.

EFFECT OF METAL IONS ON ENZYME ACTIVITY

• The enzyme activity is activated by Mn2+, Ca2+ and Mg2+, and inhibited by Cu2+, Hg2+ and Al3+.

APPLICATION

• In the process of wool deweighting, acid protease can destroy the scales on the surface of wool fibers, prevent wool from felting and enable easy dyeing on the wool.
• The recommended optimum conditions for initial trial with small dosage rate is: 0.6-2.0% (owf), pH 3.0~3.5, temperature 40 ~ 50℃, bath ration 1: 20~40, treatment for 60~ 90 minutes, deweigthing rate can reach 1~4%.

PACKAGING

• AP-100L is packaged in 25kg or 30kg HDPE plastic drums. Customized packaging is also available upon request.

STORAGE

• Typical shelf-life is six months if this product is stored at 0∼ 10°C in its original packaging, sealed and unopened, protected from the sunlight. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided.

SAFETY & ENZYME HANDLING

• Inhalation of enzyme dust and mists should be avoided.
• In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes.
• For detailed handling information, please refer to the appropriate Material Safety Data Sheet.
