Yellow passion fruit juice (PFJ, Passiflora edulis f. flavicarpa) is an important component of many
tropical fruit beverages, but limited data exist on its antioxidant chemical composition and stability
during processing and storage. PFJ fortified with ascorbic acid (450 mg/L) and sucrose (10%) was
compared to a nonfortified control, and each was evaluated with and without vacuum deaeration to
remove dissolved oxygen. Following pasteurization, juices were stored for 28 days at 37 °C to
accentuate physicochemical changes.
