A powdered juçara pulp was produced by spray drying, and its physicochemical 10 characterization and stability at different storage conditions was evaluated. The drying 11 process had a yield of 66%, and an anthocyanin-rich powder was obtained (7079.19 12 mg/100g cyaniding-3-glucoside). There was a retention of 90% of total phenolic 13 compounds (14084.65 mg/100g), and no significant alteration on the antioxidant 14 capacity was observed (ABTS: 858.59 μmol de Trolox/g; ORAC: 4155.39 μmol de 15 Trolox/g). Powdered juçara pulp presented agglomeration characteristics, with 16 solubility of 72.93% and density of 0.42 g/cm3. The anthocyanin content and the 17 powdered pulp color did not change when stored at 25°C and 7°C, in the presence or 18 absence of oxygen, for 103 days. Juçara powder showed technological properties and 19 stability to be used as an ingredient, adding functional properties to food products.
