An improved process for the production of a pancreatin product for use as enzyme bates in leather manufacture and for stripping of gelatin from photographic and X-ray films, which consists in treating finely pulped animal pancreas with sulphuric acid and then with rused calcium chloride and in blending of the thus activated pulp with powdered husk of paddy or a similar carrier material, tapioca flour or a similar starchy material, ammonium sulphate and ammonium chloride, the blended mixture being thereafter dried and finely powdered.
