PROBLEM TO BE SOLVED: To provide a method for efficiently producing a mineral drink enabling replenishing of only the mineral ingredients. SOLUTION: This method for producing a mineral drink comprises desalinating seawater using an electrodialyser so as to efficiently obtain a drink containing mineral ingredient such as magnesium and calcium and is characterized in that a monovalent selective ion exchange membrane is used as a positive ion exchange membrane to be included in the electrodialyser, seawater is desalinated to an electrical conductivity of 5-20 mS/cm, and further, the desalinated mineral water is diluted in pure water followed by adjusting the resultant product to a hardness of 100-2,000 mg/l. |
