영문 초록

We assessed the GABA accumulation and other components after the ‘Nunkeunhukchal (BGE)’, ‘Josanghukchal (BR)’, and ‘Ilmibyeo (IB)’ grain was soaked in water for 24, 36, 48, 60, 72 and 96 hr. The results showed a continuous accumulation of GABA in soaking treated brown rice of BGE and IB. Among the treated hours, 72 hours of soaking had the maximal accumulation of GABA (51.4 mg/100 g), amino acid, polyphenol and other components. The activities of glutamate decarboxylase (GAD) in brown rice and rice-bran were the same in BGE rice. However, the formation of GABA treated with L-glutamate as substrate showed dramatic increase of 354.6 (fourteen times higher than normal extraction) and 726.4 mg/100 g in BGE rice and rice-bran, respectively. These results suggested that the soaking and extraction with L-glutamate buffer could be better methods for the harvest of increased GABA.
