This study approaches the physicochemical and bioactive characterization of fresh (FR), spray dried (SD) and freeze dried (FD) jambolan (JA) and pitanga pulps (red: RP and purple: PP) varieties). In general, the concentration of bioactive compounds followed the tendency FR>FD>SD. All samples presented high proanthocyanidin content (18.7 to 121.9 g QTE/Kg-1 DW), ellagic acid (0.203 to 0.943 g/Kg-1 DW) and anthocyanins (up to 15.8 g/Kg-1 DW). In this study, JA, RP and PP powders showed activity against alpha-amylase, alpha-glucosidase and pancreatic lipase. This is the first report of protocatechuic and p-coumaric acids in fresh and spray dried red pitanga pulps. Also, this is the first time that the colorant potential and proanthocyanidin content of dried PP is shown. Overall, this research presents fresh data about these tropical fruits and demonstrates the multifunctional attributes of these understudied Myrtaceae examples of Brazilian biodiversity.
