Abstract
A process is disclosed for isolating an enzyme mixture useful in the treatment of devitalized tissue from crude bromelain. The process comprises the steps of: (1) suspending the crude bromelain in a weakly basic buffer, preferably sodium borate buffer, to selectively dissolve the active enzyme mixture; (2) separating the undissolved solids from the solution; and (3) removing small molecules having a molecular weight of 10,000 or less from the solution.
