Solid oxidized glutathione salt and production method thereof

Abstract

A solid oxidized glutathione salt and its production method: by making oxidized glutathione The salt formed of the oxidized glutathione and the cation is produced by heating to a temperature of 30° C. or higher while being in contact with an aqueous medium containing water and / or a water-soluble medium, and the salt is a solid.

Description

technical field

[0001] The present invention relates to techniques for improving the operability of oxidized glutathione. In addition, oxidized glutathione is useful as health food, pharmaceuticals, cosmetics, fertilizers, etc., or as an intermediate for the production of these products. Background technique

[0002] Oxidized glutathione (GSSG), like reduced glutathione (GSH), is useful in fields such as health foods, pharmaceuticals, cosmetics, and fertilizers, and is known to have detoxification effects, for example (Non-Patent Document 1, etc.).

[0003] Oxidized glutathione (GSSG) is a molecule obtained by oxidizing two molecules of reduced glutathione (GSH) composed of glutamic acid, cysteine, and glycine to form a disulfide bond. Composed of tripeptides (L-γ-glutamyl-L-cysteinyl-glycine).

[0004] As a method for producing oxidized glutathione, for example, a production method (Patent Document 1, Patent Document 2, etc.) is known in which an aqueous solution or yeast...
