EXTRACTION OF FUCOIDAN
The extraction method of the fucoidan from Cladosiphon okamuranus.
There are no problems, such as corrosion in a manufacturing facility, and the fucoidan which has a desired average molecular weight within the limits is related with the extraction method of the fucoidan obtained efficiently.
PROBLEM TO BE SOLVED: To provide an extraction method that gives fucoidan of a relatively high average molecular weight with no problem of corrosion of the facility and the like in the production installation. SOLUTION: When fucoidan is extracted from a seaweed, Cladosiphon okamuranus, an organic acid is used in an amount of 1-100 g/1,000 g of the seaweed and the pH in the extraction process is adjusted in the range from 2 to 6.
