One of the most frustrating things about making a healthy snack is that the fruits and veggies you sliced up to enjoy later often turn brown before you can eat them. This discoloration, caused by exposure to oxygen, is perfectly safe to eat. But it doesn’t look great, and it might make you less likely to want to eat your snacks.

There are a few different ways you can keep your apple slices from turning brown. Some work better than others, and some only work for a short period of time. It really depends on what your goals are. If you’re looking for a long-term solution, might want to try dipping your apple slices in lemon juice or using a fruit freshness spray. If you’re looking for something quick and easy, you can try covering your apple slices with plastic wrap or aluminum foil.

What Causes Apple Slices to Turn Brown?

When cut open, apples release a small amount of an enzyme called polyphenol oxidase (PPO). In the presence of oxygen, PPO causes the apple slices to turn brown. To prevent this, you need to create a barrier between the apple slices and the oxygen in the air.

Prevention Methods

Use Lemon Juice

One of the most effective ways to keep apple slices from turning brown is to coat them with lemon juice. Lemon juice is rich in citric acid, which acts as a natural preservative. Simply coat the slices in fresh lemon juice, or spritz them with bottled lemon juice, before storing them in the fridge. You can also add a few drops of lemon juice to the water when you are prepping the apples – just be sure to drain the water before storing the apples.

Store in a Cool, Dry Place

After you have washed and dried your apples, store them in a cool, dry place. The best place to store apples is in the fridge where they will stay fresh for up to two weeks. However, if you don’t have room in your fridge, you can also store them in a cool pantry or basement.

When storing apples, be sure to keep them away from ethylene-producing fruits like bananas and tomatoes. Apples release ethylene gas as they ripen, which speeds up the ripening process of other fruits and vegetables. So, if you store them together, your apples will turn brown much faster.

Wrap in Plastic Wrap

When you wrap apple slices in plastic wrap, the ethylene gas that the apples emit cannot escape. This gas is what causes the apples to turn brown. By keeping the gas trapped inside the wrap with the apples, you can help keep your apple slices fresh and white for a longer period of time.


There are many methods that can be used to keep apple slices from turning brown. Some of these methods include using lemon juice, salt water, or vinegar. You can also try freezing the apple slices or using an airtight container.
