Abstract:
The property of polyphenol oxidase (PPO) in two Jujube cultivars `Dongzao' and `Lizao' was studied, including phenols, specificity on substrates of PPO and effects of pH and concentration of substrate on PPO activity. It was showed that both Jujube cultivars had an optimum pH range,the value was 7.0 The optimum native substrate of PPO in `Dongzao' was gallate, and in `Lizao' was asafoetida acid.
Key words: Jujube fruit, Polyphenol oxidase, Phenols
