Why do the cut surface of fruits and vegetables turn brown?
Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.
Is blackening of brinjal is a physical change?
The reaction that occurs, which is called oxidation, is what turns the fruits and vegetable brown. It is also known as enzymatic browning. So, it is a chemical change.

This is known as enzymatic browning. Keep cut fruits, such as apples, pears, bananas, and peaches from turning brown by: Coating them with an acidic juice such as lemon, orange, or pineapple juice. Use a commercial anti-darkening preparation with fruits, such as Fruit-Fresh®*, and follow the manufacturer’s directions.
Is it bad to eat oxidized fruit?
When the chemicals within the fruit become oxidized by enzymes like polyphenoloxidase, the reaction causes an unappealing brown color. There’s no evidence, however, that oxidized fruit is bad for you. As they feed on the fruit’s exposed innards, the cells multiply rapidly.
