To provide functional water having functions of cleaning, sterilizing, deodorizing and mildewproofing food such as vegetables, a kitchen utensil, the floor and wall of a kitchen, the floor and wall of a factory for manufacturing or processing food.
The functional water contains the electrolytic water obtained by electrolyzing water containing sodium hydrogen carbonate or the like and a silver ion. The electrolytic water to be used is preferably diluted with the activated water of the volume of 3-40 times, which is filtered by using silicon compound-based semiconductor ceramic as a filter medium, and preferably contains sodium chloride of 0.1-0.7 mass% (preferably, 0.1-0.6 mass%). The silver ion is supplied from a silver compound (for example, Ag2O) contained in a resin molding (consisting of a polyethylene resin or the like) coming into contact with the electrolytic water. The content of the silver compound in the resin molding is 0.03-0.20 mass% (preferably, 0.08-0.15 mass%).
