Weight loss of curacao apple was considerably reduced by film wrapping during storage at 10 deg C for 7 days. The total sugar content was not significantly different in the control and wrapped curacao apple (0.24-0.4 mg/gFW). In both of non-wrapped and wrapped curacao apple, ascorbic acid progressively decreased with storage time (0.45-0.2 mg/gFW). Phenol content was higher in the control (3.5 micro g gallic acid/gFW) than the wrapped curacao apple (2.0-2.5 micro g gallic acid/gFW). Since the PPO activity in both experiments was every low (0.08-0.1 unit/min), in the non-wrapped curacao apple, chilling injury (surface pitting) occurred within day 3 after storage.
