The FRAP values of the antioxidant extracts from black rice
were demonstrated in Table 3. These extracts from waxy or nonwaxy
black rice with different cooking methods performed significant
difference (p < 0.05) in their FRAP values. The FRAP value of
raw waxy black rice was 1.05 mmole FE/100 g. For the different
period of cooking for porridge, the FRAP values were not influenced
similarly.
