In summary, amongst the rice samples, red pericarp
advanced breeding lines extracts were the most effective
in antioxidative reactions, unlike the MR219, which
showed weak antioxidant abilities. Even though both red
pericarp advanced breeding lines showed only half of the
activity of Thailand rice in the TPC and FRAP assays,
their tocochromanol content was comparable to the mean
values of Thailand rice. However, due to the smaller
number of investigated rice variants in this study, the
effect of colour or pigmentation was not as pronounced as
that found in other studies. We demonstrated that wholekernel
red rice is a good source of phenolics and tocols.
Consumption of red rice, which has been shown to be a rich source of these compounds, could then be
recommended in ordinary diet to enhance the daily intake
of vitamins and thus are interesting for food products.
