Popis:	The present study has its aim to evaluate the different dimensions of organic vegetables quality from the Brazilian family-run farm, especially the evaluation of composition, antioxidant activity, microbiological characteristics and pesticide residues. There were evaluated carrot, broccoli, kale and white cabbage grown by organic farmers in the highlander region of Rio de Janeiro state. There were determined humidity, lipids grade, total protein content, mineral residues (ashes), soluble and insoluble fibers, soluble solids, total acidity, pH, and pesticide residues. The antioxidant activity was determined using DPPH (2, 2-diphenyl-1-picrylhydrazyl) free radical removal. Among the analyzed vegetables, the effectiveness of the antioxidant capacity was obtained, in decreasing order, by broccoli, kale, white cabbage and carrot. According to the microbiological parameter, evaluated vegetables have shown satisfactory sanitary quality. Pesticide residues were not found above the detection limit for both authorized and unauthorized analyzed crops.
