NEW AND EFFICIENT ENZYMATIC MEDIA COMPOSITION AND OPTIMIZATION WITH PROCESS FOR DEHAIRING OF HIDES

摘要

The present invention provides an enzymatic culture medium for unhairing of skin and hides with an unhairing agent for use in an Unhairing step in tanning for producing leather comprising an alkaline protease as an active component; a treatment solution optimized with a pH-adjusting agent and the enzymatic Unhairing agent; a method for enzymatic unhairing treatment in tanning for producing leather comprising contacting the treatment solution with a raw hide or skin; and a leather thus produced. It is designed to optimize the medium constituents and explain the combined effects of medium constituents, viz., glycerol, K2HPO4 and KH2PO4 and complex nitrogen and metal ions.
