CONTAINER-PACKED ASPALATHIN-CONTAINING BEVERAGE, METHOD FOR PRODUCING SAME, AND METHOD FOR IMPROVING STORAGE STABILITY OF ASPALATHIN IN CONTAINER-PACKED ASPALATHIN-CONTAINING BEVERAGE

摘要

The purpose of the present invention is to provide: a container-packed aspalathin-containing beverage having excellent aspalathin storage stability; a method for producing the same; and a method for improving the storage stability of aspalathin in a container-packed aspalathin-containing beverage. The present invention relates to a container-packed beverage in which an aspalathin-containing beverage is loaded into a container, wherein: the aspalathin-containing beverage contains ascorbic acid and/or a salt thereof, and aspalathin; the concentration of the ascorbic acid and/or a salt thereof in terms of ascorbic acid is 50-500 ppm; the concentration of the aspalathin is 25 ppm or more; the pH is 6.5 or less; and the volume of the headspace inside the container is no more than 15% of the volumetric capacity of the container.
