Technical Abstract: Whole-grain pigmented rice products can contribute diverse functional components to the diet to promote improved gastrointestinal health in humans. We are isolating feruloylated arabino-oligosaccharides and proanthocyanidin polymers from red-pigmented rice bran to evaluate individual and synergistic bioactivity in promoting innate immune responses in human colonocytes. A better understanding of the function, bioavailability, and interactions of these rice bran components in colon ecosystem functioning will determine their dietary utility and identify effective processing technologies for formulating safe, high quality rice products containing these components in a sustainable manner. We present our results to isolate these components from red rice bran and their bioactivity in modulating T84 colonocyte response to pro-inflammation factors.
