ABSTRACT:
Disclosed is a method of removing nitric acid from an aqueous liquid containing various components such as vegetable extract, and nitrate ion is removed selectively without spoiling the taste or other components, by subjecting the aqueous liquid to chromatographic treatment with an amphoteric ion exchanger to separate nitrate ion from other components contained in the aqueous liquid. A nitric acid-reduced drink is produced by preparing a raw drink material comprising an extract or juice of plant tissue; removing nitric acid from the raw drink material with use of the method of removing nitric acid from an aqueous liquid as described above; and preparing a drink using the raw drink material after the removing of nitric acid.
