Functional properties of encapsulated Cagaita (Eugenia dysenterica DC.) fruit extract

Cagaita (Eugenia dysenterica DC.) is an important native Brazilian fruit species with potential health effects associated with its concentration and profile of polyphenols. The aim of this work was to evaluate the total phenolic (TPC), total proanthocyanidins, the antioxidant, antimicrobial, and anti-obesity potential of cagaita extracted, dried and encapsulated powders. Samples were produced with gum arabic or inulin as the carrier using different spray-drying conditions. E. dysenterica powders had a content of total phenolics between 9.9 and 31.2 mg GAE/g DW, which correlated with antioxidant capacity. Powders also showed inhibitory activity against Staphylococcus aureus and Listerya monocytogenes similar to vancomycin, erythromycin and ceftriaxone used as controls, and also showed inhibition of α-amylase and α-glucosidase. Preparation of dry extracts from cagaita using spray-drying is an alternative to prevent deterioration of the bioactive compounds present in the fruit, ensuring quality and availability of the fruit during the off-season.
