Answer 2

Covering the fruit or vegetable will prevent oxygen from reaching the cut cells, and thus prevent oxidation. Cook, boil, or otherwise heat the fruits and vegetables right after cutting them to prevent oxidation. When you cook fruits and vegetables, the heat destroys the enzymes that cause oxidation and the resulting discoloration.
