Abstract
Buriti (Mauritia flexuosa L) is an Amazonian fruit with high potential to be used as a source of bioactive compounds and healthy food preparations due to its attractive yellow / orange color. The purpose of this paper was to verify the physicochemical characteristics, bioactive compounds and antioxidant activity in pulp, endocarp, peels, and three food paste developed with Buriti pulp and waste. In addition to the centesimal composition of the fractions of the fruit and the preparations, analyzes of vitamin C, phenolic compounds, carotenoids and antioxidant activity were also carried out. The following values were observed for the fractions of the fruit: vitamin C (48.44-55.22 mg/100 g), carotenoids (6.05-21.03 mg/100g), Total phenolics (19.31-33.30 mg GAEq/100g) and antioxidant activity (111.24-190.43 µmol TE/g DM), for all analyzed parameters, the highest values were observed for the peel. As for the formulations, it was found that the good attributes of the peel interfered in the formulation C, which presented the highest yields of vitamin C (21.22 mg/100g), carotenoids (13.99 mg/100g), Total phenolics (21.45 mg GAEq/100g) and antioxidant activity (82.34-130.52 µmol TE/g DM). Thus, it is verified that buriti has a great nutritional potential for direct consumption or to be used in the formulation of confectionery products, including the use of its peels in formulations.

The Amazon region has an immense variety of fruits, unknown by the rest of the world and with a great potential for industrial use, such as the buriti (Mauritia flexuosa L.) [1] Fruits, such as buriti in general, have their consumption highly recommended for obtaining antioxidant compounds, such as vitamin C, carotenoids and phenolic compounds, notably beneficial to health, since epidemiological studies indicate that a nutrition rich in this fruit, as well as other vegetables , are associated with a lower risk of chronic diseases, due to the presence of an adequate mixture of phytochemicals [2]. This plant is better known as buriti, but it has other names such as: miriti, carandá-guaçú, carandaí-guaçú, muriti, palm-buriti, palm-dos-brejos, mariti, bariti, meriti, it can be designated as the tree of life, and for scientists it is titled by the scientific name of Mauritia flexuosa L.
