Fruits and vegetables are prone to discoloration after damage during transportation, packaging or processing, a phenomenon known as enzymatic Browning. The basic step of enzymatic Browning reaction is to oxidize phenolic compounds into o-quinones catalyzed by phenolase, and then quinones undergo a series of oxidative condensation polymerization to form brown products, which leads to Browning. Vitamin C is a common anti-browning agent, which can prevent Browning through 2 different mechanisms: In the absence of Polyphenol oxidation (PPO) substrate, it irreversibly inactivates PPO, possibly by binding to its active site; In the presence of PPO substrate, vitamin C will reduce the reaction product of PPO oxidation, that is, conjugate oxidation with the quinone formed by oxidation, and the quinone is reduced, resulting in the regeneration of phenol, thereby inhibiting Browning
