The correct answer is the air reacts with the enzymes in the banana.

  • Bananas turn brown in color because the air reacts with the enzymes in the banana.
  • The life cycle of a banana starts with a deep green color.
  • The deep green color of bananas changes to a delicious yellow and ends with a brown color.
  • The unripened bananas are a light green color that begins to yellow as they ripen.
  • Bananas contain an enzyme called polyphenol oxidase that reacts with oxygen in the atmosphere and coats the banana with a sort of rust that accounts for the dark brown color.
  • Ethylene hormone helps for the ripening process.
  • Large amounts of ethylene leads to the decaying of yellow pigments in bananas and it will change into brown color.
  • The processes of formation of brown spots on a banana is called enzymatic browning.
