The results
showed that the TPCs of white rice and green rice (124.81 mg/
100 g and 159.95 mg/100 g, respectively) were significantly lower
than those of black and red rice. Yao et al. (2010) found that black
rice (8.58 g/100 g) possessed the highest TPC among the three
strains studied (red, purple and black rice); the TPC of black rice
was 86-fold greater than that of red rice (0.1 g/100 g).
