ABSTRACT:
The preparation of a pepsin extract from the stomach of pigs, sheep or cattle, which is suitable for the bating of hides, is presented. The process involves macerating the stomach mucous, sedimenting the material, reserving the middle layer for pharmaceutical preparation, combining the other two layers, drying them and adding salt for preservation. The resulting pepsin containing material is particularly suitable for acid enzymic bating of chrome tan hides after the pickle process with the main purpose of obtaining a higher surface yield and a softer leather.
