It was selected some fruits and vegetables which were separated from leaves, stems, bark and seeds. It was analyzed the nutritional composition and total phenols. After recipes were developed using the leaves, stalks, husks and seeds, which were evaluated by sensory analysis. The fat content ranged from 0.03% (stalk of spinach and beet) to 2.27% (pumpkin seed). The protein content ranged from 0.51% (banana husk) to 9.56% (melon seed). Most samples had about 1% ash and fiber content ranged from 0.72% to 16.02%. The higher content of polyphenols was found in orange husk (631.25mg) and the lowest in the papaya seed (22.53mg). It was concluded that by identifying the nutritional composition of the portions of food usually discarded the use of these parts can be better direct in preparing various recipes, which are enriched nutritionally.
