In addition to providing novel compositional data, a more detailed nutritional and functional characterization of jabuticaba and jussara and their fractions (peel, seed and pulp) will hopefully allow assessing the technological potential of these fruits and value-added products, thus contributing to the sustainable use of Brazilian Atlantic Forest resources. Therefore, the aim of the present study was to determine the antioxidant activity and the chemical composition of jabuticaba and jussara fruits and their fractions , with emphasis on phenolic compounds, carotenoids, tocopherols and minerals.
