When the fruit’s cells are broken, both via reducing, bruising, or just getting old, enzymes generally known as polyphenol oxidases (PPO) are launched. These enzymes react with phenolic compounds current throughout the apple tissue, within the presence of oxygen. This oxidation course of creates o-quinones, which subsequently polymerize to type melanins. Melanins are pigments answerable for the browning impact.
