Screening and Identification of Genotypes for Natural Color from Grain Amaranth (Amaranth sp.)
Abstract:
Nature exhibits a wide range of colours in the form of plant pigments that are used as dyes. Anthocyanin is one such water soluble pigment responsible for an attractive red to blue colour and is known to possess high antioxidant activity. Research on grain amaranth thus far has been focussed on production and productivity besides its nutritive quality. The present study highlights on extraction of anthocyanin from grain amaranth, an underutilized crop. Total anthocyanin content (TAC) (mg/g) in leaf, inflorescence and stem peel was estimated and evaluated statistically (1% and 5% level of significance). Leaves, stem-peel and inflorescence of grain amaranth considered as a waste material after seed extraction is apotential source of anthocyanin adds value.
