Abstract :
This study was performed to evaluate the enhancement of functional components of germinated rough rice. Rough rice was germinated at 37 °C for 6 days, and subjected to a high hydrostatic pressure treatment (HPT) at 30 MPa for 24 h (HP24) and 48 h (HP48). Germinated rough rice without HPT (HP0), HP24, and HP48 were analysed for their functional components. The highest γ-aminobutyric acid, total arabinoxylan, and tricin 4′-O-(threo-β-guaiacylglyceryl) ether contents were 121.21 mg/100 g, 10.6%, and 85.82 μg/g, respectively, after HP48 for 2 days. γ-Oryzanol contents increased from 23.19–36.20 mg/100 g (at HP0) to 31.80–40.32 mg/100 g (at HP48). The highest vitamin B (60.99 mg/100 g) and E (4.07 mg/100 g) contents were observed after HP24 for 5 and 2 days, respectively. These results suggest that a combination of HPT and germination efficiently enhances the functional characteristics of rough rice.
