dried (40 °C) and processed to obtain parboiled brown and parboiled
polished rice grains. For the parboiled brown grains, a significant reduction
in the concentration of TSPCs was observed compared to
brown rice (Table 2), with a reduction of 48.6% for light brown pericarp
color grains, 73.0% to 87.0% for red pericarp color grains and
32.8% for black pericarp color grains. This reduction in the concentration
of polyphenols in the parboiled brown grains is related to the loss
of phenolics in the water during parboiling, thermal decomposition or
interactions with other components of the grains.
