The synthesis of the immobilization carrier of polyphenol oxidase(PPO): polyvinyl alcohol grafted glutamic acid resin(PGAR) has been studied and the structure of the PGAR has been characterized by IR and DTA techniques. The results showed that the PPO was immobilized onto the carrier resin through coordination with Cu²⁺, forming PGAR-Cu-PPO. The optimum pH for immobilization was 5.59 and 6.64, and the Michaelis-Menten constant was of 1.70×10^-2 mol/L, both are the same as those for free PPO. The immobilized PPO can be used repeatedly and the activity was found reduced by 80% after being reused 5 times.
