Abstract
The changes in the levels of $\gamma$ -aminobutyric acid (GABA) and some free amino acids were investigated in germinating brown rices. Ungerminated brown rices were germinated for 72 hrs by application of the following solutions: 1) distilled water, 2) 50 ppm lactic acid, 3) 5 mM glutamic acid. The GABA levels were enhanced in all germinated states of brown rices compared with ungerminated ones, highest in the germinated brown rices by 5 mM glutamic acid solution. Alanine levels were also enhanced significantly in the germinated brown rices. The levels of aspartic acid and glutamic acid were decreased significantly in all the germinated states. The levels of serine decreased during germination in the solutions of water and lactic acid were increased by the germination in the glutamic acid solution. The data show that germination of brown rices by the application of the glutamic acid solution can significantly increase the levels of GABA and can restore the serine level.
