The present invention relates to the production of fucoidan that efficiently precipitates fucoidan with stable viscosity expected from various pharmaceuticals, flocculants, thickeners, and surfactants from fucoidan extracted aqueous solution. It is an object of the present invention to provide a fucoidan having a method and viscosity stabilized. [MEANS FOR SOLVING PROBLEMS] By adding at least one salt selected from salts of calcium, magnesium and zinc, which are food additives, and a mixture of these salts, and ethanol to fucoidan extract, the viscosity is stabilized and the safety is high. Fucoidan can be obtained with good yield. [Selection figure] None |
