PROBLEM TO BE SOLVED: To provide a method for producing a composition containing a high content of γ-aminobutyric acid by using asparagus containing a large amount of γ-aminobutyric acid as a raw material and efficiently and simply using its endogenous enzyme. High γ-aminobutyric acid is characterized by enriching γ-aminobutyric acid by treating asparagus and / or asparagus extract under an environment of 10 ° C to 50 ° C for 1 minute to 15 days. A method for producing a containing composition, preferably, when enriching γ-aminobutyric acid, at least one selected from the group consisting of glutamic acid, glutamate, pyridoxal phosphate, pyridoxine hydrochloride is added, and Preferably, the method for producing a high γ-aminobutyric acid-containing composition, which is an asparagus extract obtained by sterilizing and filtering the asparagus extract with a filter having a pore size of 1.0 μm or less. [Selection figure] None |
