Chapter 7: Pigmented Millets: Nutritional Quality and Potential Benefits for Human Health

Millets exist in a variety of colours, and their kernel colour is a key criterion for determining market value and nutritional quality. Carotenoids and polyphenols are naturally occurring pigments distributed in varied quantities in different species of pigmented millets. These compounds not only provide health benefits, but also help in the prevention of chronic disorders related to oxidative stress. Because of their high concentrations of minerals, polyphenols, vitamins, and a range of biologically active chemicals, pigmented wheat and rice have recently garnered considerable attention. However, minor cereals with great local significance, like pigmented millets, are yet to be explored. This chapter comprehensively describes colour-imparting compounds in millets, i.e. carotenoids and anthocyanins, their nutritional characteristics, and potential health implications.
