Abstract: The present study results indicate that electrodialysis has differents effects on ingredients of orange juice, and their change tendencies are related to pH. pH is regarded as controlling index of deacidification. Voltage, flow rate and temperature have effects on isolation efficiency of electrodialysis, and the optimum parameters are voltage of 60 V, flow rate 550 L/h and temperature 15 ℃.
