Antioxidant activity and correlations with bioactive components from commercial products of cupuaçu

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.
