Abstract
A method of preparing a purified proteolytically active chymopapain from crude chymopapain extracts by the use of exchange resin absorption purification techniques is provided. The purified chymopapain is characterized by relative freedom from proteolytically inactive, colored and/or toxic components and by its failure to form a precipitate with barium chloride test solution (U.S.P.) under acid conditions.
