Process for conveniently prepared rice product was improved to enhance its health benefits. Brown
aromatic rice (Kao Dawk Mali 105 cultivar) was soaked in water at 25 C and 35 C for 12 h and 24 h,
incubated for 24 h and dried. Higher GABA content (15e17 mg/100 g) was observed in germinated brown
rice (GBR) with soaking at 25 C for 24 h and 35 C for 12 h. Subsequently GBR (soaking at 25 C for 24 h)
was cooked in boiling water or pressure cooker and dried to produce quick cooking germinated brown
rice (QCGBR). Cooking time of QCGBR was reduced to 3.6e4.2 times. Pressure cooking provided lighter
QCGBR (p < 0.05) and higher hot paste viscosity, cold paste viscosity and setback than those of boiling,
however, panelists could not detect any differences of sensorial quality (p 0.05). GABA content
significantly reduced after QCGBR development process (p < 0.05). To improve health benefit of the
product, GBR was cooked under pressure and kept at chilling temperature for 24 h and 48 h before
drying. Rehydrated QCGBR prepared by chilled storing cooked GBR for 48 h had noticeably more resistant
starch of 0.74 g/100 g compared to those of cooked brown rice (0.29 g/100 g) and cooked GBR (0.36 g/
100 g).
