The potential sources of coloring pigments are Betalain and Betacyanins are present in Beet root and Amaranth respectively. Extraction of these natural color used various novel techniques like ultrasonic assisted extraction, Microwave assisted extraction. . Betalain pigment can be used as a natural additive for food, cosmetics and drugs in the form of beet juice as well as beet powder and Amaranth plant can be a good source of antioxidants. Aim of this study is that to how to extract natural color , study various novel techniques of extraction especially ultarsonication and microwave assisted extraction techniques and their efficiency and suitability.
