Sulfur amino acid-containing composition

摘要

Provision of a composition stably comprising a high concentration of sulfur amino acid derived from a plant belonging to the genus Allium. A method for producing a sulfur amino acid-comprising composition comprising: heating a plant belonging to the genus Allium; treating the plant belonging to the genus Allium thus heated with a γ-glutamyl bond cleaving enzyme; and subjecting the resulting enzyme-treated product to ion exchange chromatography.

1. A method for producing a sulfur amino acid-comprising composition, wherein the sulfur amino acid is at least one selected from the group consisting of S-1-propenyl-L-cysteine sulfoxide, S-propyl-L-cysteine sulfoxide, S-methyl-L-cysteine sulfoxide and S-allyl-L-cysteine sulfoxide comprising:
heating a plant belonging to the genus Allium, fragmenting the heated plant, directly treating the fragmented plant with a γ-glutamyl bond cleaving enzyme to produce an enzyme-treated product, and subjecting the enzyme-treated product to ion exchange chromatography to obtain a composition comprising at least one selected from the group consisting of S-1-propenyl-L-cysteine sulfoxide, S-propyl-L-cysteine sulfoxide, S-methyl-L-cysteine sulfoxide and S-allyl-L-cysteine sulfoxide.
