Abstract
Butia capitata, native to the Brazilian cerrado, is underutilized for human consumption. The objective was to determine the physical characteristics of the fruit, centesimal composition, bioactive and antioxidant activity. Fruits obtained in Montes Claros, Minas Gerais, Brazil. Diameter, height and weight were evaluated. The moisture was analyzed by gravimetry after oven drying, ashes by calcining in a muffle furnace, proteins by the Kjeldahl method, gravimetric lipids after extraction in ethyl ether, carbohydrates by difference and total energy value by conversion factors. Vitamin C, E and carotenoids were analyzed by HPLC, minerals by inductively coupled plasma atomic absorption spectrometry, Folin Ciocalteu solution phenolic compounds, anthocyanins by spectrophotometry and antioxidant capacity by the Radical DPPH. The fruits presented good pulp yield (68.59%), which has a high lipid content (3.42 g.100 g-1) and total energy (83.34 kcal.100 g-1). The pulp contains ß-carotene (8.56 mg.100 g-1), vitamin E (121.07 mcg.100 g-1) and high concentrations of vitamin C (53.57 mg.100 g-1), total phenolics (493, 6 mg.100 g-1) and copper (1.80 mg.100 g-1). Almond has a high value of total energy (457.72 kcal.100 g-1), vitamin E (1594.39 mcg.100 g-1) and minerals Cu (2.40 mg.100 g-1) and Mo (0.9.100 g-1). The pulp is a source of carotenoids, vitamin C, copper and total phenolics, both natural antioxidants.
