It is an object of the present invention to provide porphyran (gimdang) modified with physiological activity and physical properties, and to manufacture and use thereof.n n n The salts are separated from the sulfuric acid group in porphyran to remove the salt, and the salts of the sulfuric acid group in porpyran are separated to form porpyran which is a free sulfuric acid group, thereby producing porphyran modified in physiological activity and physical properties. In addition, after the salt is separated and removed from the sulfate group in the porphyran, the sulfate is converted into a sulfate of the salt using a predetermined salt, or the salt of the sulfate group in the porpyran is converted by ion exchange to convert the salt into a predetermined salt. By doing so, porphyran modified in the physiological activity and physical properties of porphyran is produced. In addition, the porphyran of the present invention can be used as a cosmetic or food product having hyaluronidase inhibitory activity in addition to cosmetics and food.n n n Porphyran, seaweed, seaweed |
