The highest of protein in brown rice was maturity of 44 days with 8.10 ± 0.100 percentage, the rather than were
37 and 30 days (7.43 ±0.020 and 7.05 ± 0.050 percentage) respectively. It was significant difference (p<0.05).
Quantity of protein in germinated brown rice by three different mature had lower than brown rice. The highest of
protein in germinated brown rice was maturity of 44 days after flowering (7.51 ± 0.100 percentage), the rather than
were 37 and 30 days. GABA content in brown rice was a little amount (<0.25 mg./100 g.) compared with
germinated brown rice. The highest of GABA content in germinated brown rice was maturity of 37 day after
flowering with 40.97 ± 0.02 mg./100 g., the second were 44 and 30 days (25.89 ± 0.01 and 16.70 ± 0.20
mg./100 g) respectively. These showed significant difference (p<0.05). It was indicated that the higher quantity of
protein was followed by harvesting maturity. The maximum of protein accumulating in rice was 44 days after
flowering but different from GABA content in germinated brown rice which maximum at 37 days after flowering.
