<p>A method is disclosed for treating proteinaceous films or preformed capsule walls with proteolytic enzymes to afford cold-water solubility. According to the process of this invention, preformed films or capsule walls are partially degraded enzymatically, in an aqueous vehicle, to such a degree that the degraded proteinaceous material is rendered soluble in cold water at some desired or required temperature of use. Such treatment of already made films or capsule walls is contrasted with enzymatic treatment of proteins before manufacture of the films or capsule walls themselves.</p> |
