Use of bacaba peel for the development of hydroelectrolytic beverages and their consumer acceptance

Abstract The hydroelectrolytic beverages segment has been expading its market and introducing new flavors in order to meet the demand for new products. However, experimental studies find concerns about the chemical compositions of these drinks. The aim of this study was to develop a drink without synthetic coloring or flavoring, with functional attributes based on the bacaba (Oenocarpus bacaba Mart.) peel extract. Two hydroelectrolytic drinks were developed, one hypotonic and the other isotonic, containing 0.5 and 1.0% of bacaba peel extract. Physicochemical characterization, determination of total phenolic compounds, anthocyanins, and antioxidant capacity were perfomed, in addition to color evaluation, as well as sensory analysis by means of preference tests. The developed formulations showed potential antioxidant activity and natural red coloring due to the phenolic compounds and anthocyanins present in the beverages. The sensory evaluation indicated positive acceptance by the tasters regarding the addition of the bacaba peel extract to the beverage formulations. The developed formulations demonstrated that the use of the bacaba peel is a viable option for the production of sports drinks, acting as a natural dye and offering health benefits due to its bioactive compounds.
