    摘要: What is disclosed is a method for the recovery of hair from an animal hide and for a concurrent opening of the hide structure using a proteolytic enzyme, which method comprises first pre-treating the hide, free of preservative salt, in the acid pH region with a material cleaving disulfide bridges and then, without a previous softening, concurrently loosening hair and opening the hide structure by treating said hide with a protease, effective in the alkaline region, at a pH value of about 11 to about 13.
