Proximate, mineral composition and antioxidant activity of traditional small millets cultivated and consumed in Rayalaseema region of South India.

BACKGROUNDMillets are a diverse group of small seeded grasses, widely grown around the world as cereal foods. This communication details the proximate, mineral profile and antioxidant activity of six different small millets (Finger, Foxtail, Proso, Little, Barnyard and Kodo millets) and their 21 cultivars that are traditionally cultivated and consumed in the region of Ralayaseema, south India. RESULTSThe proximate analysis revealed that these millets are rich in protein, fat, ash (mineral), total dietary fibre and total phenols with appreciable antioxidant activity. However, starch and amylose content was comparatively lower as compared to major millet sorghum. ICP-MS analysis of small millets demonstrated that they are rich in minerals such as Ca, P, K, Mg, Fe, Cu, Zn, Mn, Cr, Mo and Se. CONCLUSIONFinger and kodo millets were found to be nutritionally superior over other small millets. The results suggest that small millets have a potential to provide food security and can combat micronutrient malnutrition. (c) 2017 Society of Chemical Industry
