In this study, the phenolic content, antioxidant capacity, antimicrobial activity and bioaccessibility in different fruit purees were evaluated. Strawberry (Fragaria ananassa Duch.), starfruit (Averrhoa carambola) and other fruits native from Brazil, such as açaí (Euterpe oleracea), acerola (Malpighia emarginata), araçá (Psidium guineenses), cambuci (Campomanesia phaea), jabuticaba (Myrciaria cauliflora), murici (Byrsonima verbascifolia), panã (Annona crassiflora) and pitanga (Eugenia uniflora) were evaluated. Among the fruits studied, acerola exhibited high antioxidant activity and high concentration of total phenolic compounds. Individual bioactive compounds were determined by UPLC-QToF-MS. A wide range of organic acids, flavonoids and phenolic acids were found in the samples. Fruit puree extracts (6–25 mg/mL) inhibited bacterial growth, especially those from strawberry, acerola, starfruit and pitanga. Overall, up to 8% of the TPC were bioaccessible after gastrointestinal digestion. The findings support the notable potential of fruit purees as sources of bioactive compounds of industrial interest.
