Standardization of osmotic drying time for apple pops and apple rings

Osmo-dried apple pops and rings were prepared from “Golden Delicious” apples. The technology has been optimized for osmo-dried apple pops with a diameter of 28 mm and apple rings with a thickness of 0.5 cm. In case of apple pops drying time of eight hour for sugar syrup and seven hours for honey syrup at 70^oB osmotic sugar syrup at 50°C was optimized. The drying time of five hours has been optimized for osmo-dried apple rings with sugar and four hours for osmo-dried rings with honey. Honey osmo-dried apple pops and rings rated better in quality and sensory characteristics and with less water activity. The developed technology can be explored commercially at an industrial level for the production of quality osmo dried apple pops or apple rings.
