Study by Absorption and Emission Spectrophotometry of the Efficiency of the Binary Mixture (Ethanol-Water) on the Extraction of Betanin from Red Beetroot

Abstract In this paper, we intend to present a method of extraction and analysis of betanin from Algerian red beetroot, and to know the efficiency of the binary mixture (Ethanol-Water) on the extraction. This dye is a natural pigment with high antioxidant power and widely used as a natural dye. In addition, the high bioavailability of this pigment reinforces its potential for future therapeutic applications. However, the betanin content of commercially available beet extracts never exceeds 1.2% and this molecule does not exist marketed in a more purified form, it is therefore necessary to have efficient tools for the enrichment of betanin extracts. The experimental results made in our laboratory, confirm the effectiveness of the binary mixture (Ethanol-Water) on the extraction of betanin from Algerian beetroot.
