PRODUCTION OF LOW SALT SOYSAUCE AND APPARATUS THEREFOR

摘要

PURPOSE:To provide a method for production of low salt soysauce capable of reducing pH change of the soysauce and lowering the salt content without changing the amino acid composition in the soysauce by utilizing an electric dialyzer and an apparatus therefor. CONSTITUTION:This apparatus for production of low salt soysauce has an electric dialyzer composed of one or more repeating units involving a cation- exchange membrane (C), a bipolar membrane (B) and an anion-exchange membrane (A) sandwiched between both the cathode 3 and the anode 2 and arranged in that order from the anode 2 side and one or more other repeating units involving a cation-exchange membrane (C) and an anion-exchange membrane (A) arranged in that order. The method for production of low salt soysauce is carried out by using this apparatus, sending the soysauce to a desalting chamber and reducing the salt content in the soysauce.
