The invention relates to the enzymatic treatment of a proteinaceous substrate with a first enzyme, such as a sulfhydryl oxidase. The first enzyme removes enzyme inhibitors, such as free thiols, present in the proteinaceous substrate. The removal of the inhibitory compounds in the substrate allows for an effective enzymatic action of a second enzyme such as protein cross-linking of the protein present in the substrate by tyrosinase enzymes.
