Development of isotonic beverage with functional attributes based on extract of Myrciaria jabuticaba (Vell) Berg

Abstract Isotonic repositories are specially designed to promote rehydration during or after physical exercise. These beverages are processed for commercialization from synthetic flavorings and dyes with sensorial characteristics similar to those of fruits, in order to attenuate their natural acidity. The aim of the present study was to develop two formulations of isotonic drinks without synthetic dyes and with functional attributes based on concentrated hydroethanolic extracts of peel and pulp of Myrciaria jaboticaba. Determination of chemical (sodium, potassium and calcium, total phenolics, ...
