Polyphenol oxidase (PPO) is mainly found in animals, plants, microorganisms and culture cells. PPO is a copper-contained oxidase that oxidizes monophenols and diphenols to produce quinones. It is closely related to fruit and vegetable processing, tea quality and tissue culture.
Measurement Principle：
PPO can catalyze o-dihydroxybenzene to produce quinones which has absorbance at 410 nm.
