Total phenolic content (TPC)
The TPC of four fractions of KDML 105 rice grown at different
locations are shown in Table 2. There were significant differences
detected amongst these fractions. The TPC of bran fraction had
the highest value (2.5–2.7 mg GAE/g) whilst milled rice had the
lowest TPC (0.5–0.7 mg GAE/g). All fractions of rice from site 2
showed the greatest TPC compared to other sites. The TPC of husk
and brown rice fractions from different sites were significantly different
(p < 0.05). Rice fractions from site 1 showed the lowest TPC
results. However, there were no significant differences between
the fractions of rice samples from site 2 and site 3 observed. This
might be due to similarities in growth conditions.
