Grumixama (Eugenia brasiliensis Lam.) cultivated in the Cerrado has high content of bioactive compounds and great antioxidant potential
Abstract
ABSTRACT: 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 (Goiás 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.
