“…The GABA concentration in barley and wheat is less than 2 mg/100 g of dm (Ohm et al, 2016), while in regular brown rice grains it ranges from 3 to 7 mg/100 g of dm (Banchuen, Thammarutwasik, Ooraikul, Wuttijumnong, & Sirivongpaisal, 2009;Charoenthaikij et al, 2010;Chen et al, 2016). It is present in higher concentrations in sprouted barley and wheat (7 to 25 mg/100 g) (H. Chung, Jang, Cho, & Lim, 2009;Ohm et al, 2016), and especially sprouted brown rice (35 to 80 mg/100 g of dm) (Banchuen et al, 2009;Chungcharoen et al, 2015;Cornejo et al, 2015;Ohm et al, 2016;Ohtsubo et al, 2005;Roohinejad et al, 2011;Thitinunsomboon, Keeratipibul, & Boonsiriwit, 2013). Charoenthaikij et al (2010), Cornejo et al (2015), and Roohinejad et al (2011) observed a 8-to 12-fold increase in GABA content in brown rice when sprouted for 2 to 4 days at 27 to 35°C.…”
