          Abstract

          O cupuaçu é considerado um importante fruto tipicamente amazônico e apresenta polpa ácida, agradável e de aroma característico. Esses atributos de qualidade o colocam no ranking das exportações de frutas. No Brasil, o cupuaçu é consumido principalmente na forma de polpa congelada. Os estudos com marcas comerciais de polpa de cupuaçu que correlacionaram a atividade antioxidante aos níveis de compostos bioativos mostraram que a capacidade de sequestro de espécies radicalares, pelo método do radical ABTS, apresentou correlação positiva com os compostos fenólicos e não com os carotenoides e a vitamina C. Porém, todas as marcas avaliadas apresentaram diferenças significativas quanto aos teores de vitamina C, carotenoides e capacidade antioxidante total equivalente ao trolox.

          Translated abstract

          The cupuaçu is considered an important Amazonic fruit, which presents acidic pulp, pleasant and characteristic flavor. This quality attributes places the cupuaçu in the ranking of exporting fruits. In Brazil, the cupuaçu is mostly consumed as frozen pulps. Studies with cupuaçu pulp brands correlated antioxidant activity with the levels of bioactive compounds and showed that antioxidant activity carried out through the ABTS radical presented a positive correlation only with the phenolic compounds and not with carotenoids and vitamin C. However, all the evaluated brands showed significant differences in the levels of vitamin C, carotenoids and trolox total equivalent antioxidant capacity.
