PROBLEM TO BE SOLVED: To provide a method for more efficiently producing a beverage more tasteful and more stable in quality when preserved for a long time by using a new 'deaeration-treated water' in the case of extraction from and dilution of the beverage material. SOLUTION: This method comprises: preparing a deaerated and ion-exchange treated water obtained by removing an ion component of e.g. a metal ion or chloride ion and unnecessary organic substances and by subjecting a gas component of e.g. oxygen or chlorine to deaeration treatment; and subjecting a beverage material to extraction by using the water treated as above, adding the water to the beverage material for preparation, or dissolving the beverage material of e.g. vitamins in the water. An inert gas is used to replace the air inside the apparatus and systems in the manufacturing process of the objective beverage so as to sever contact between the beverage and air. |
