The 4-aminobutyric acid (γ-aminobutyuric acid, GABA) Was accumulated steeply in the rice germ during water soaking. GABA-enriched rice germ work effectively to lower the blood pressure of patients of hypertension. However, the rice germ have a high amount of oil that will be rancidity. In this study, we tried a deffating of the rice germ without inactivation of gulutamate dehydrogenase. The oil content was decreased to 3.9% (w/w) from 21.5% (w/w) and the accumulated GABA content increased to 328 mg/100g from 251mg/100g after defatting of the rice germ with n-hexane for 2h at 40°C. High temperature of defatting decreased the oil content. There was no effect of defatting temperature on the amount of accumulated GABA contents. However long time proseeding decreased the accumulated GABA content. There was no effect to GABA-accumulation of solvent change to acetone from n-hexane. However, ethanol decreased the accumulated GABA content. And the residue of solvent, n-hexane have no effect on GABA accumulation, but ethanol decreased the content of accumulated GABA during water soaking.
