Abstract(s)
O presente trabalho apresenta uma revisão da literatura que evidencia a importância nutricional, fitoquímica e propriedades biológicas das sementes de melancia. Neste trabalho de revisão bibliográfica foram descritos os principais nutrientes, compostos antioxidantes das sementes, tais como ácidos fenólicos, flavonoides, alcaloides, bem como a sua associação às atividades biológicas benéficas que os mesmos poderão exercer no metabolismo humano.
Foi possível concluir que as sementes de melancia são fontes de proteínas, ácidos gordos essenciais, vitaminas e minerais. As propriedades funcionais e medicinais são atribuídas à presença de compostos bioativos como ácidos fenólicos, flavonoides, carotenoides e alcaloides, que são excelentes fontes de antioxidantes naturais.
As sementes desta fruta, apesar de terem valor nutricional e energético, são geralmente descartadas como subproduto alimentar. Recentemente, o uso potencial de subprodutos alimentares no desenvolvimento de novos ingredientes saudáveis para o enriquecimento de alimentos tem sido uma forma de reduzir a poluição e garantir a sustentabilidade ambiental.
Conclui-se assim que, pelo seu teor nutricional, composição química, propriedades biológicas e farmacológicas descritas, estas podem ser adicionadas aos alimentos para os enriquecer, utilizadas como suplemento alimentar e até incorporadas em fármacos, bem como utilizadas na cosmética.
This study presents a literature review which shows the nutritional, phytochemical and biological properties of watermelon seeds. In this research, the main nutrients, antioxidant compounds of watermelon seeds, such as phenolic acids, flavonoids and alcaloids, as well as their association with beneficial biological activities that they may exert in human metabolism. It was possible to conclude that watermelon seeds are a source of proteins, essential fatty acids, vitamins and minerals. The functional and medicinal properties are attributed to the presence of bioactive compounds such as phenolic acids, flavonoids, carotenoids and alkaloids, which are excellent sources of natural antioxidants. The seeds of this fruit, although having a nutritional and energetic value, are usually discarded as a food by-product. Recently, the potential use of food by-products in developing new healthy ingredients for food enrichment has been a way of reducing pollution and ensuring environmental sustainability. In conclusion, due to the nutritional and chemical richness of watermelon seeds and taking into account their biological and pharmacological properties, they can be added to foods to enrich them. They can also be used as food supplements and even incorporated into drugs and cosmetics.
