CONTAINER-PACKED BEVERAGE, APPARATUS FOR MANUFACTURING REDUCTION BEVERAGE, AND METHOD FOR MANUFACTURING REDUCTION BEVERAGE

摘要

PROBLEM TO BE SOLVED: To provide a container-packed beverage having a negative redox potential to be sustained for prevention of oxidation, with improved taste and flavor.SOLUTION: An apparatus for manufacturing a reduction beverage includes an insulation container 3 made of electrical insulator having a low electric conductivity which is accommodated in an outer container 2 having an internal space for accommodation, and quartz diorite porphyrite slurry 5 having a negative redox potential or water having a redox potential reduced to negative which is accommodated in a space 4 having a predetermined capacity formed between the internal surface of the outer container 2 and the external surface of the insulation container 3. A beverage (a beverage D to be processed) is accommodated in the insulation container 3 for a predetermined time, so that a reduction beverage R having a redox potential reduced to negative is accommodated in a closed container.
