Acid Protease AP-10

A powder protease can hydrolyze plant and animal proteins under acidic conditions, capable to destroy the scales on the surface of wool fibers, thus prevent wool from shrinking and enable it easier for dyeing.

DESCRIPTION
Acid Protease AP-10 is produced from robust strains of 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-10 is suitable for the production of leather.
