How to Keep Apples from Turning Brown: Tips and Tricks


Apples are a versatile and delicious fruit that can be eaten raw, cooked, or used as a snack or decoration. However, they have a tendency to turn brown quickly when exposed to air, which can make them unappetizing and spoil their appearance. Therefore, it’s important to know how to keep apples from turning brown and how to preserve their freshness for as long as possible. In this article, we will explore some effective and easy ways to prevent apples from browning and enjoy them at their best.

Covering the Apples

One of the simplest and most common methods of keeping apples from turning brown is to cover them with a protective layer that prevents air and moisture from reaching their flesh. There are several options for covering apples, depending on your preferences and needs.

Plastic wrap is a convenient and widely available option that can be wrapped tightly around the apple to create a seal. However, it is not eco-friendly or biodegradable and can create waste.

Beeswax wraps are a more sustainable and reusable alternative that can be wrapped around the apple and secured with a knot or clip. They come in different sizes and designs and can be washed and reused multiple times.

Airtight containers, such as plastic or glass containers with a lid, can also be used to keep apples fresh for longer. They are especially useful for storing sliced apples or apple pieces and can be stacked in the fridge or freezer.

Whatever method you choose, make sure to seal the apple tightly and keep it in a cool, dark place to maximize its freshness and prevent browning.

Adding Lemon Juice

Lemon juice is a natural and effective way to prevent apples from turning brown by inhibiting the oxidation process that causes browning. It contains ascorbic acid, also known as vitamin C, which acts as an antioxidant and neutralizes the free radicals that cause browning.

To use lemon juice, simply squeeze some juice onto the apple slices or pieces and toss them gently to coat them evenly. You can also mix lemon juice with water or sugar to balance the taste and create a fruity and refreshing salad, pie filling, or snack.

Here are some recipe suggestions that incorporate lemon juice:

  • Apple salad with olive oil, feta cheese, and lemon juice
  • Classic apple pie with lemon juice and cinnamon
  • Healthy apple chips with lemon juice, cinnamon, and honey

Remember to use fresh and ripe apples for best results and adjust the amount of lemon juice to your taste.

Blanching the Apples

Blanching is another method of preventing browning by exposing the apple to high temperature for a short period of time, which deactivates the enzymes responsible for the browning reaction. This method is especially useful for cooking or freezing apples, but may affect their texture and flavor if used incorrectly.

To blanch apples, follow these steps:

  1. Wash and peel the apples, and remove the core and seeds
  2. Slice the apples into even pieces or wedges
  3. Bring a pot of water to a boil and add the apple slices
  4. Boil the apples for 1-2 minutes, depending on their size and thickness
  5. Remove the apples from the boiling water and immediately immerse them in a bowl of ice water to stop the cooking process
  6. Drain the apples and pat them dry with a clean towel
  7. Use the blanched apples in your recipe or store them in an airtight container in the fridge or freezer

Keep in mind that blanching may alter the texture and flavor of the apples and make them softer or more tender depending on the duration of the process.

Using Saltwater

Saltwater is another effective and inexpensive way to prevent apples from turning brown by deactivating the enzymes through a process called osmosis. Saltwater draws the moisture out of the apples and inhibits the browning reaction, while preserving their natural taste and texture.

To use saltwater, follow this recipe:

  1. Dissolve 1 tablespoon of salt in 1 cup of water in a bowl
  2. Add the apple slices or pieces to the saltwater solution and stir them gently
  3. Let the apples soak in the solution for 5-10 minutes, depending on their size and thickness
  4. Remove the apples from the solution and rinse them with clean water
  5. Pat the apples dry with a clean towel and use them in your recipe, snack, or decoration

Keep the saltwater solution ratio constant even if you use a different amount of water.

Commercial Products

Finally, there are several commercial products available that are designed to prevent apples and other fruits from turning brown, such as ascorbic acid, citric acid, or Fruit Fresh. These products work by providing a protective layer around the fruit surface and inhibiting the enzymatic reaction that causes browning.

However, using commercial products may have some drawbacks, such as the cost, availability, and possible side effects from artificial or chemical ingredients. Always read the labels and instructions carefully before using any commercial product and choose the one that fits your needs and preferences.


Keeping apples from turning brown is easy and essential to preserve their freshness and quality. By using some of the methods and tips we have suggested in this article, you can enjoy apples in various forms and recipes without worrying about their appearance or taste.

Remember to cover the apples, add some lemon juice, blanch them, use saltwater, or try a commercial product if you prefer.
