SOLID OXIDIZED GLUTATHIONE SALT AND METHOD FOR PRODUCING SAME

摘要

A solid oxidized glutathione salt is produced by heating an oxidized glutathione at 30°C or higher while the oxidized glutathione is brought into contact with an aqueous medium in the presence of a substance for providing a cation, to produce the salt of the oxidized glutathione and the cation as a solid, wherein the aqueous medium is composed of water and/or a water-soluble medium, and the cation is at least one selected from an ammonium cation, a calcium cation and a magnesium cation.
