Apples turn black due to exposure to oxygen, causing a process known as oxidation. When the apple's flesh is cut or bruised, enzymes react with oxygen in the air, leading to browning. To prevent this, apply a bit of lemon juice to the cut surfaces; the ascorbic acid in lemon juice helps slow down the oxidation process.
