Cartilage of fish is treated with enzyme or alkali so as to obtain an aqueous solution, which is then defatted, deodorized, decolorized, filtrated, and dried, such that a mucopolysaccharide is produced. Alternatively, cartilage of fish is pressure-treated so as to obtain an aqueous solution, which is then treated with enzyme, defatted, deodorized, decolorized, filtrated, and dried, such that a mucopolysaccharide is produced. According to the present invention, a mucopolysaccharide such as chondroitin sulfuric acid can be produced in a short time and at a low cost. Further, the mucopolysaccharide produced is used as a cosmetic material or food material, for example. |
