Polyphenol oxidases oxidize polyphenols found in fruits and vegetables, causing postharvest disorders such as avocado browning to occur.
Polyphenol oxidase (PPO) enzymes, also known as polyphenoloxidases, are able to catalyze the transformation of an array of aromatic compounds that have two adjacent phenolic groups on them. This includes a number of polyphenols in plants that act as antioxidants. These copper-containing enzymes oxidize the phenolic groups to reactive oxygen molecules known as quinones, which continue reacting with each other and other cellular factors to form brown spots known as melanin. This browning causes the deterioration of fruits and vegetables, causing large economic losses. Examples include the browning of bananas and avocados.
