COMPOSITE MATERIAL OF DE-N-ACETYLATED CHITIN AND FIBROUS COLLAGEN

摘要

Problems with conventional collagen materials such as insufficient strength are overcome by a composite material of de-N-acetylated chitin and fibrous collagen. This material may be prepared by bringing the de-N-acetylated chitin and the fibrous collagen into mutual contact in an aqueous acidic medium followed by deacidifying the product obtained. The fibrous collagen can be partially replaced by gelatin and/or soluble collagen. The composite material finds use in medical materials, as an edible casing for food and as a base material for immobilizing an enzyme.
