MARINE ALGAE FOOD FOR GASTRIC POTASSIUM FOR SODIUM ION EXCHANGE

摘要

Desalinating food is prepared by demetallizing the tissue of a marine alga by treating it with an inorganic acid and then contacting it with an aqueous solution containing potassium ions to effect replacement of the metal ions therewith. The food can adsorb a large amount of sodium ions with simultaneous dispensation of potassium ions in the living body and is suitable for dietetic care of patients for whom a decrease of salt ingestion is essential.
