Abstract
O objetivo deste estudo foi avaliar a composição de folhas, talos, cascas e sementes de vegetais, elaborar preparações utilizando essas partes e verificar a sua aceitabilidade. Foram selecionadas algumas frutas e hortaliças das quais foram separadas as folhas, talos, cascas e sementes. Foi analisada a composição centesimal e o teor de fenóis totais. Após, foram desenvolvidas preparações utilizando as folhas, talos, cascas e sementes, as quais foram avaliadas sensorialmente através do teste afetivo de aceitação. O teor de lipídios variou de 0,03% (talo de espinafre e talo de beterraba) a 2,27% (semente de moranga). O teor de proteínas variou de 0,51% (casca de banana) a 9,56% (semente de melão). A maioria das amostras apresentou em torno de 1% de cinzas e o teor de fibras variou de 0,72% a 16,02%. O teor mais elevado de polifenóis foi encontrado na casca da laranja (631,25mg 100g-1). Os resultados da análise sensorial demonstraram que 77% das preparações obtiveram notas acima de 5 (gostei). Conclui-se que, através da identificação da composição nutricional das partes dos alimentos, usualmente descartadas, pode-se direcionar melhor seu uso na preparação de várias receitas.
The objective of this study was to evaluate the composition of leaves, stems, bark and seeds of vegetables, prepare recipes using these parts and to verify the acceptability of them. 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.
