Detailed explanation-1: -Enzymic browning is a reaction which requires the action of enzymes and oxidation in order to occur. What happens during enzymic browning? Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction).
Detailed explanation-2: -Browning: Enzymatic Browning Polyphenol oxidase (PPO) present in most fruits and vegetables, and some seafood, is responsible for enzymatic browning. In addition to PPO, the presence of peroxidase, a similar oxidative enzyme, may initiate enzymatic browning of fruits and vegetables.
Detailed explanation-3: -Subsequently, these quinones and their derivatives are polymerized through several reactions, forming a relatively insoluble brown pigment known as melanin [5]. The rate of enzymatic browning is determined by the enzymatic activity of PPOs.
