What causes apples to brown?
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
What happens when you put an apple in water with vitamin C?
This is because vitamin C is an antioxidant that reacts with the very reactive oxygen-centred radicals, turning them into less reactive species. Hence, this reduces the amount of oxidative damage to the apple flesh. This is why the apple in the vitamin C solution does not turn brown and remains fresh looking.
Do apples turn brown in water?
Using Water, Lemon Juice, and Citric Acid to Prevent Apples From Browning. One of the easiest things you can do to prevent browning is to submerge the cut fruit in plain water, which reduces the amount of air, and therefore oxygen, that can get to it.
