| 摘要 |
This invention provides a composition capable of efficiently exhibiting various kinds of physiological activities possessed potentially by seaweeds of the genus Porphyra. The laver protein-containing composition is obtained by adding water, a saline solution or an aqueous dilute alkali solution to seaweeds of the genus Porphyra or finely divided dry particles thereof, wet milling the materials to extract soluble components therefrom, and separating proteins form the extract. A composition containing different kinds of laver proteins may be obtained by separately conducting extraction with water, a saline solution or an aqueous dilute alkali solution, or a composition containing a mixture of laver proteins may be obtained by conducting such extraction procedures successively. The laver protein-containing composition thus obtained is used as a food helpful to health because it has a blood pressure-dropping action, a hepatic function-improving action, a lipid metabolism-improving action, a peripheral blood vessel-expanding action and a blood viscosity-reducing action.
