This study was carried out to obtain more information about the physicochemical properties, composition, and antioxidant activity of pitanga fruits (Eugenia uniflora L.), particularly fruits from the State of Rio Grande do Sul, Brazil. Pitanga with different flesh colors (purple, red, and orange) from tree selections cultivated at Embrapa Clima Temperado (RS-Brazil) were analyzed. Only slight differences were observed in the quality parameters and in the proximate and fatty acid compositions among the fruits studied. The extracts from purple-fleshed pitanga had the highest total phenolic and anthocyanin contents along with the highest antioxidant capacity. The antioxidant capacity (DPPH and FRAP assays) of methanolic pitanga extracts was highly correlated... |

Food industry generates a significant amount of seed wastes from the juice production, frozen pulps and jams. Considering that the characterization of wastes is the first step to determine their potential use, the aim of the present study was to determine the composition and the antioxidant capacity of seeds from pitanga fruits with different flesh colors (purple, red and orange). Chemical composition results revealed that pitanga seeds are a good source of insoluble dietary fiber, with low protein and fat levels, and no relevant differences were found among pitanga seeds from different flesh colors. Pitanga seed extracts had powerful antioxidant capacity that was partially correlated to their high phenolic content and showed some variation according to... |
