ABSTRACT:
A process for preparing a composite comprising an insoluble protein matrix and an oleaginous material, which is useful as a material for surgical dressings and biomedical implants, and as a cosmetic material for application to the skin. The process comprises the steps of mixing a protein, the oleaginous material and water to form an emulsion of the oleaginous material in an aqueous dispersion of the protein, and subsequently drying or freeze-drying the emulsion to form a film or a sponge.
