Kalu Heenati red rice anthocyanin bran extraction: phenolic profiles and low-glycemic cooking?

Kalu Heenati is a celebrated indigenous Sri Lankan red rice variety rich in proanthocyanidins, polyphenols, and soluble fiber, delivering a low glycemic index (GI under 50). To cook unpolished whole grains without stripping the nutrient-dense aleurone and bran layer, the rice must be soaked in clean spring water for at least four hours prior to cooking. This hydrates the stubborn pericarp. Cook in an earthenware pot using a 1:2.5 water ratio; bring to a rolling boil over wood embers for 15 minutes, then cover with a tight lid and let it steam in its own residual heat for 20 minutes to preserve heat-sensitive antioxidants.
