It is intended to provide a process for producing a gamma-aminobutyric acid-containing composition which contains gamma-aminobutyric acid in a definite amount or more in terms of nutritional value. A gamma-aminobutyric acid-containing composition which contains gamma-aminobutyric acid in a larger amount than the existing products can be produced by a process comprising: the step of disrupting the cell wall of beans or bean pods to give a disrupted cell wall product; the step preparing a liquid reaction mixture wherein a liquid reaction mixture containing the disrupted cell wall product and water is prepared; and the low-temperature reaction step wherein the liquid reaction mixture is maintained at 4 to 15oC for a period of time required for substantially increasing the content of gamma-aminobutyric acid.
