| Summary: | This study aimed to investigate the effect of different carrier agents on the physicochemical properties and antioxidant activity of the spray-dried pomegranate juice. Maltodextrin and gum Arabic were used at 20% and 30%, respectively. The results revealed that spray-dried pomegranate juice with 20% gum Arabic exhibited higher drying yield and bulk density than other powders. Spray-dried powder with both concentrations of maltodextrin (20% and 30%) demonstrated higher water solubility and lower hygroscopicity and moisture content than that of gum Arabic. Anthocyanin content (4.64 mg/L), phenolic content (528.40 mg GAE/g), and antioxidant activity (1288.5 mM GAE/g DW for FRAP and 363.9mM GAE/g DW for DPPH) were all noticeably higher in powder with 20% maltodextrin compared to the powder encapsulated with gum Arabic. The type and concentration of carrier agent did not significantly affect the colour properties of the pomegranate juice powder. |
