PROBLEM TO BE SOLVED: To provide an extraction method that gives fucoidan of a desired average molecular weight in high yield with no problem of corrosion of the facility and the like in the production installation. SOLUTION: In this extraction process, fucoidan is extracted from the seaweed, Cladoiphon okamuranus, with pressurized hot water in an autoclave. The extraction temperature is set to 100-120 deg.C, the extraction pressure is set to 1.0-2.0 atmospheric pressure and the extraction is continued for 0.2-16 hours. |
