PURPOSE:To produce a food having improved salt reducing action by ion exchange such as adsorbing sodium and releasing potassium in the living body, by using seaweed as a raw material. CONSTITUTION:Seaweed is treated with a folution of an inorganic acid, e.g. hydrochloric or sulfuric acid, preferably at <=2pH to remove metals contained in the seaweed tissue through chemical bonding. The resultant treated seaweed is then treated with a solution containing potassium ions e.g. an aqueous solution of potassium hydroxide, to bond potassium to functional groups in the seaweed. |
