PURPOSE:To reduce the content of salt in soy sauce without losing the balance of amino acids in the soy sauce. CONSTITUTION:Anion exchange membrane A, cation exchange membranes C and a bipolar membrane B are successively arranged between both a cathode and an anode. A soy sauce, an alkaline solution and an acidic solution are allowed to pass through respectively between the anion exchange membranes A and the cation exchange membranes C, between the cation exchange membrane C and the bipolar membrane B, and between the anion exchange membrane A and the bipolar membrane B, and a direct current voltage is simultaneously applied between both the cathode 3 and the anode 2 to reduce the content of salt in the soy sauce. |
