NEVES, Leandro Camargo et al. Production of blends based on tropical and native fruits from brazilian Amazon. Rev. Bras. Frutic. [online]. 2011, vol.33, n.1, pp.187-197. Epub Mar 18, 2011. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452011005000023.
The aim of this work was to obtain the nutritional enrichment of nectars of fruits, by means of blends processament, using tropical and Amazonian fruit produced in Roraima. Nectars of pineapple, buriti, cashew, camu-camu, star fruit, passion fruit, murici, Tahiti lime and taperebá were used. A preliminary assay was carried out where it was observed that the nectars of pineapple and passion fruit would be used as matrix, and from these ones the following treatments were originated: 2 controls - 100% of pineapple and 100% of passion fruit; 1 blend using the matrix - 50% of pineapple + 50% of passion fruit; 7 blends of each matrix with which chosen fruit in the proportion of 1:1. The sodium benzoate and sulfur dioxide were added in the concentrations of 500 and 200 ppm, respectively, in all nectars and evaluated blends. The results regarding the nutritional composition of blends reflected a significative raise of nutritional values when compared to the matrix, as well when compared to the individual nectars of each fruit. The same behavior was observed even after 10 days of no refrigerated storage. Regarding the microbiological stability, just the blends in which buriti was used as component were damaged. The blends chemical analysis showed different standard in relation to the matrix, however, when submitted to the sensorial analysis, showed to be satisfactory by the panel. The compositions that more enjoyed the panel were the blends of both matrix associated to camu-camu and murici.
