Zusammenfassung: | Grumixama (Eugenia brasiliensis Lam.) is a Brazilian berry native to the Atlantic Rainforest. Information on nutritional and bioactive profiles of the fruit cultivated in the Brazilian Savannah (Cerrado) is not available in literature. The aim of this study was to investigate the physical and proximate composition; mineral, total phenolics, total tannins and total carotenoids contents; and antioxidant capacity (DPPH and FRAP assays) of the dark purple grumixama cultivated in the Cerrado area (Goias State). Results showed a similar physical and proximate composition to those of grumixama native to the Atlantic Rainforest. However, grumixama from Cerrado presented the highest dietary fiber and magnesium contents. In addition, the Cerrado grumixama showed higher content of total phenolics (with a large amount of tannins), carotenoids and antioxidant capacity than those of grumixama native to the Atlantic Rainforest, cherry, blueberry, and fruits native to the Cerrado. Thus, the consumption of whole fruit (peel, pulp and seed) in healthy diets and its use as an ingredient for functional food products should be encouraged. Key words: Eugenia brasiliensis Lam., nutrients, bioactive compounds, polyphenols, antioxidant activity. Grumixama (Eugenia brasiliensis Lam.) e uma 'berry 'nativa da Mata Atlantica. Informacoes sobre o perfil nutricional e bioativo do fruto cultivado no Cerrado nao estao disponiveis na literatura. O objetivo deste estudo foi investigar a composicao fisica e centesimal; o conteudo em minerais, fenolicos totais, taninos totais e carotenoides totais; e a capacidade antioxidante (ensaios DPPH and FRAP) da grumixama roxa cultivada na regiao do Cerrado (Estado de Goias). Os resultados mostraram uma composicao fisica e centesimal similar a da grumixama nativa da Mata Atlantica. Entretanto, a grumixama cultivada no Cerrado apresentou teores de fibra alimentar e magnesio superiores. Alem disso, a grumixama do Cerrado apresentou maiores teores de compostos fenolicos totais (com grande quantidade de taninos) e carotenoides e maior capacidade antioxidante do que os teores da grumixama nativa da Mata Atlantica, cereja, mirtilo e frutos nativos do Cerrado. Assim, o consumo do fruto inteiro (casca, polpa e semente) em dietas saudaveis e seu emprego como ingrediente em produtos alimenticios funcionais devem ser estimulados. Palavras-chave: Eugenia brasiliensis Lam., nutrientes, compostos bioativos, polifenois, atividade antioxidante. |
