Good quality powder can be prepared from aonla juice by spray drying. It may be consumed as health drink after reconstitution, because of its high vitamin C content and antioxidant capacity. An experiment was conducted to evaluate the antioxidant activity and other quality parameters of spray dried powder prepared from aonla juice stored up to one year. The juice, extracted from aonla cv. Chakaiya, was pasteurized at 90 C for 2 min and preserved with 500 ppm SO2 in food grade carboys at room temperature (18–40 C).
