PROBLEM TO BE SOLVED: To obtain a defatted food material reduced in the content of free fatty acids contained in the material to enable the improvement in the flavors of embryo foods, and capable of being applied to the field of foods on the comprehensive aspects of tastes, digestion, cooking processing, maintenance, etc. SOLUTION: This defatted food material enriched in γ-aminobutyric acid is obtained by extracting off lipids from at least one of rice embryo, rice bran containing the rice embryo, wheat embryo and wheat bran containing the wheat embryo, and subsequently immersing the defatted product in water under conditions comprising a pH of 2.5-7.5 and a temperature of <=50 deg.C. Concretely, the defatted food material is obtained by extracting off the lipids from the material with subcritical or supercritical carbon dioxide and subsequently immersing the defatted product in water under the conditions comprising a pH of 2.5-7.5 and a temperature of <=50 deg.C. |
