Potential value addition of underutilized kodo and little millet: Study of antinutrients, phytochemical content and invitro bioaccessibility of its polyphenols

Millet, ultrasonication, phytochemical, antioxidant, antinutrient, bioaccessibility

Millets have turned into a food choice for people soon because of its ease in cultivation, nutritive value and various other super nutrients which makes it a super food. The effect of ultrasonication and germination were studied on antinutrients, total phenolic content, total flavonoid content, antioxidant activity and in vitro bioaccessibility of polyphenols of kodo and little millets. The results showcased the treated kodo and little millets had higher total phenolic content (27.01±0.54 mg GAE/ 100 g extract and 44.25±0.78 mg GAE/ 100 g extract, respectively), total flavonoid content (21.23±0.68 mg QE/ 100 g extract and 4.58±0.068 mg QE/ 100 g extract), antioxidant activity (FRAP (12.34±0.11 mg TE/ 100 g extract and 27.56±0.14 mg TE/ 100 g extract), DPPH (89.89±0.70 %RSA and 88.94±0.41%RSA)) than control and lower antinutrients (tannin: 2.59±0.09 mg TAE/ 100g and 9.51±0.05 mg TAE/ 100g, respectively; phytate content: 0.166±0.003 mol/kg and 0.199±0.004 mol/kg, respectively). The bioaccesibilty of polyphenols found to be higher for treated kodo and treated little millet than control. Results contributes the scope of value addition of processed (ultrasonicated/germinated) kodo and little flours for the creation of functional products/nutraceuticals.
