Abstract: The effects of scalding temperature, scalding time and hardener on VC content, enzyme activity and hardness were studied to solve the issue of browning and softening in the processing of candied apple. The optimum processing conditions were obtained as following: the scalding temperature 100 ℃, scalding time 4 min and dipping for 3 hours, with CaCl2 (0.5%) as the hardener.

Key words: scalding, hardness, quality
