Because any reaction occur.
you don't
It can be used as an anti-oxidant. It stops the oxygen in the air to interact with the food. Ex. If you cut up apples in slices they will get brown and 'floppy' from oxidizing this happens quite fast. If you sprinkle some lemon juice over the cut apple slices they will not go brown and stay crisp .

A household item that can help preserve apples in lemon juice. Using lemon juice will prevent the apple from turning brown which is caused by an enzyme.
All you have to do is keep them in a plastic bag with a tiny bit of air in it and put in the fridge. But eat them soon! Also coating them with lemon juice will prevent them going brown ^^^The air is what turns them brown, so that will not work. Lemon juice or orange juice will, though. It is the acid in the juice that prevents them from oxidizing and turning brown.

Hypothesis 1: When you disturb the skin of an apple by cutting the apple into half, the exposed area will turn brown due to exposure to air.Hypothesis 2: If you snugly wrap or cover the exposed area of an apple after cutting it (disturbing the skin), you can slow down how fast the inside turns brown. Hypothesis 3: If you remove all of the skin of an apple and let it sit in the air, the outside will turn brown but the inside will not turn brown at the same rate. Hypothesis 4: If you remove all the skin of an apple AND slice the whole apple into pieces, all sides exposed to air will turn brown; if some slices are thicker, the inside will turn brown more slowly than the exposed outside areas.
Dried apples have nothing in them but apple. The liquid has been removed. Some apples might have sulfites or other color preservatives added to keep the slices from turning brown during drying. Check the ingredient statement.
