AbstractThe objectives of this study were to determine the effects of rice cultivars and some factors of anthocyanin extraction from pigmented rice bran (RB) on total phenolic content (TPC), total anthocyanin content (TAC) and DPPH-scavenging activity (DPPH). The investigated parameters for the extraction were cultivars of pigmented rice bran namely: Homnil cultivar (RB1), Rice berry cultivar (RB2) and Hommali dang cultivar (RB3), particle size (40, 60 and 80 mesh), shaking conditions (shake and non-shake), type of solvents (distilled water 95 percent ethanol:1.5N HCl 85:15(v/v), and 0.5, 1, 1.5 and 2 percent (w/v) citric acid), extraction time (1, 2, 3 and 4 h) and temperature (room temperature (RT), 40, 50, 60 and 70 deg C). The results showed that the appropriate extraction parameters were Homnil cultivar (RB1), particle size at 60 mesh, shaking, 2 percent (w/v) citric acid and extracted for 3 h at 40 deg C. The obtained TPC, TAC and DPPH scavenging activity were 320 g gallic acid equivalent (GAE)/100g, 238.02 mg cyanidin g/100g and 87.09 percent respectively. Therefore, pigmented rice bran extract could be extracted for potentially use as food or beverages ingredients.
