Spray drying of juçara pulp aiming to obtain a "pure" powdered pulp without using carrier agents

The aim of this work was to investigate the possibility of obtaining a juçara pulp powder by spray drying with no carrier agent addition. The pulp was filtered and then dried in a lab scale spray dryer. The process yield was relatively high (66%) and a highly anthocyanin-rich (7,079 ± 83 mg/100 g cy...

Description
Summary:The aim of this work was to investigate the possibility of obtaining a juçara pulp powder by spray drying with no carrier agent addition. The pulp was filtered and then dried in a lab scale spray dryer. The process yield was relatively high (66%) and a highly anthocyanin-rich (7,079 ± 83 mg/100 g cyanidin-3-glucoside) powder was obtained. Total phenolic content (14,305 ± 551 mg/100 g) and antioxidant capacity (4,155 ± 92 µmol of Trolox/g) were satisfactorily preserved after drying, showing similar or better results than those reported using carrier agents, as well as solubility, bulk density and morphology. Finally, pulp powder was stable for 103 days, at different storage conditions, with respect to color, anthocyanin content and antioxidant capacity, showing potential to be used as a natural colorant or antioxidant in food products.
