Sourced so far mostly from beet root juice, betanin is a red-violet natural colorant increasingly used by the food, beverage, and nutraceutical industries. The production and purification methods, emerging sources, extraction technologies and applications are reviewed. Moreover, we provide an updated bioeconomy perspective on this valued betacyanin whose supply and applications, as we argue in this study, will rapidly expand.
