New red rice transgressive variants with high antioxidant capacity
Red coloured rice, has been shown to contain high levels of bioactive properties. The aim of this study was to quantify the major antioxidant compounds in the whole grain of two new red rice transgressive variants together with their parents which was determined by the oxygen radical absorbance capacity (ORAC) method, measured in methanol extract. A Thailand commercial red rice was used as a control. Although, the ORAC values for some red rice samples were similar, they were higher than light brown rice control, MR219. The antioxidant capacity was also evaluated by ferric-reducing antioxidant power assay. FRAP result was well correlated with ORAC (r = 0.94).
