Increase of GABA content with prolonging of steeping time
at ambient temperature (25e30 C) was confirmed by
Charoenthaikij et al. (2009) and Watchararparpaiboon et al. (2010).
Whereas decreasing of GABA content with extending steeping time
at 35 C might be due to the water content in the grains increased
excessively, and subsequently germination rate reduced (Chung,
Jang, Cho, & Lim, 2009)
