- •
Inhibition of PPO induced by citric or malic acid was due to the decrease of pH.
- •
Cinnamic acid reversibly inhibited PPO in a mixed-type manner.
- •
Citric acid, malic acid and cinnamic acid quenched fluorescence in different modes.
- •
Cinnamic acid bound to PPO and induced the rearrangement of secondary structure.
