Phenolic compounds and screening of the antioxidant capacity of theobroma grandiflorum dehydrated coproducts

Abstract

Theobroma grandiflorum is a fruit, belonging to the Esterculiaceae family, widely consumed in Brazil. Cupuaçu is distinguished by the characteristic flavor of its acidic pulp and intense aroma. Although, the remaining portion of pulp extraction from the bolter is neglected, although it has nutritional and functional potential due to its dietary fiber content, bioactive phytochemicals, minerals and vitamins. The aim of this study was to obtain flours from the remaining portion of the pulp extraction from the fruit pulp industry bolter of cupuaçu, to determine the phenolic compounds and the screening of the antioxidant capacity. The analytical protocols used were performed by spectrophotometric assays. The total phenolic compounds presented 403.00 mg AGE.100-1 extract and antioxidant capacity screening showed 146.90% free radical sequestration by the DPPH method, 710.10 mg of the extracts by the ABTS assay and the Reducing Power 578.40 mg.100g-1 extract compared to BHT. A strong correlation R2 ? 0. as foud etee the otets of total pheoli ostituets ad the atioidat apait epressed i EC50. It can be concluded that the analyzed matrix stands out with a source of bioactive phytochemicals and antioxidant capacity with potential of applying food industry as a functional ingredient, thus justifying the extension of the studies.
