Consequently, only the combination

Consequently, only the combination of steaming and
ethanol treatment is completely effective.
We measured the effect of steaming and ethanol treatment
on the GABA content of GBR. Table 2 shows that
the GABA content in GBR–SGT was 11.3 mg, and that
GABA content was not affected by steaming and ethanol
treatment. Watanabe, Maeda, Tsukahara, Kayahara, and
Morita (2004) reported that GABA in bread containing
brown rice and GBR was almost completely decomposed
during the baking process. They suggested that heating
decomposed the GABA; however, steaming at less than
100 C had no effect in our experiment
