PURPOSE: To provide a composition efficiently exhibiting various kinds of physiological activities latently possessed by seaweed of the genus Porphyra. CONSTITUTION: The Porphyra sp. protein-containing composition is obtained by adding water, a saline solution or a dilute aqueous solution of an alkali to a thallus or a dried finely granulated material of the seaweed of the genus Porphyra, extracting a soluble ingredient while carrying out wet grinding and conducting a separation treatment of the protein from the extract liquid. The extraction with the saline solution or the dilute aqueous solution of the alkali may separately be performed to provide each of separate Porphyra sp. protein-containing compositions or the operations may successively be carried out to mix each of the compositions.Thereby, the Porphyra sp. protein-containing composition is obtained. The resultant Porphyra sp. protein-containing composition has the physiological activities such as hypotensive actions, hepatic function improving actions, lipid metabolism improving actions, peripheral vasodilator actions and blood viscosity-lowering actions. Thereby, the composition is used as a food effective for health. |
