Question

6. Why do cut vegetables turn brown when exposed to air?​

Answer 1

Answer:

Fresh fruit and vegetables normally keep enzymes trapped in their tissues. However when the fruit is sliced, or squashed, or when the fruit or vegetable begins to break down with age, the enzymes come into contact with oxygen in the air. This causes the fruit to turn brown.
