Why does a freshly cut apple turn brown?
Why Apples Turn Brown. When an apple is cut, oxygen is introduced into the plant tissue and a chemical reaction called oxidation occurs. Apples contain an enzyme called polyphenol oxidase (PPO). When this enzyme comes in contact with oxygen, it turns colorless compounds into a brown pigment called melanin.
