How to Keep Sliced Apples from Browning

There's nothing more annoying or frustrating than slicing into a fresh, delicious apple only to see it brown just moments later. However, there are many ways to solve this issue, allowing you to enjoy vibrant, freshly cut apple slices whenever you want!

Use lemon juice. Apples turn brown because of an enzyme in the fruit that reacts with oxygen in the air. This process is known as "oxidation." Lemon juice can prevent oxidation due to its citric acid content, which is an effective antioxidant. You can use fresh lemon or pre-bottled lemon juice; this method works best with sweet apples, as fresh lemon juice can make the apple taste sour. To use lemon juice to stop apples from browning, you can try one of the following methods:

• You can soak the apple slices in a bowl of cold water mixed with lemon juice. The ratio should be one tablespoon of lemon juice to one cup of water. Soak the slices for 3-5 minutes, then drain and rinse them off.
• Lemon concentrate can also be used instead of fresh lemon juice, as it still contains the necessary citric acid for the oxidation process. Pineapple juice can also be a good alternative.

Use Salt. Salt is a natural preservative and works effectively to keep apple slices from browning. Sprinkle salt on a plate of apple slices with a spoon. To avoid making the apples too salty, don't use more than a teaspoon of salt. This method can help keep apples from oxidizing for a decent amount of time.

• Don't worry about the apples tasting salty – as long as you don't overuse the salt, the apples will still taste normal.

Use Carbonated Drinks. Carbonated beverages also contain citric acid, which helps prevent your apple slices from browning. Lemon soda and ginger ale are two common drinks you can use to soak apples.

• Simply place the apple slices in a bowl with the carbonated beverage of your choice and soak for about 3-5 minutes before removing them. You can rinse them if you wish, or just leave them as is and enjoy the new flavor!
• Seltzer water is also a good option to prevent browning, so you can try using it if you have some on hand!

Use Fruit-Fresh Powder. Fruit-Fresh powder is a blend of citric and ascorbic acids designed to prevent fruits from browning. It's said to keep fruit fresh for up to 8 hours, and you can find it in the canned goods section of most grocery stores.

• To use Fruit-Fresh powder, simply sprinkle half a teaspoon over each plate of sliced apples, making sure the powder evenly coats the surface of the slices.

Blanch the Apples. Blanching apple slices can prevent them from browning by neutralizing the enzymes in the apples that would normally react with oxygen in the air. To blanch apples, simply dip them in warm water for about 5 minutes, then remove and rinse with cold water.

• Keep in mind that this method softens the surface of the apples, making them less tasty to eat. Therefore, it's best suited for apples you plan to use in cooked or baked dishes.

Wrap with Plastic Wrap. A simple method to prevent apples from browning is to wrap the slices with plastic wrap. This technique works by blocking air from coming into contact with the apple flesh, thus preventing oxidation. Try to wrap the plastic tightly around the apple slice and avoid any folds where the wrap touches the open part of the apple slice.

• This method works best for halved apples rather than smaller slices, as it is easier to wrap a whole apple tightly.
• Be aware that even a little air trapped inside the wrap can still cause oxidation. Since it’s hard to completely eliminate air, this method isn’t the most effective one.

Use a Rubber Band. Using a rubber band is a clever and simple way to prevent your apple from browning, though this method can only be applied to apples that have been sliced but not peeled. It works by keeping the flesh of the apple from being exposed to air.

• Simply cut the apple into slices as usual, then piece them back together like a puzzle to form the shape of the whole apple. Wrap a rubber band around the apple to make it look as though it hasn’t been cut.
• This is a great option for those who want to take pre-sliced apples to work or send them with their children for lunch at school.

Choose Your Apples Wisely. Some types of apples are more prone to browning than others. If you're planning to slice your apples, it’s best to choose a variety that has a lower tendency to brown. Research on apple browning shows that: "The Arangeh apple variety is the least likely to brown. Both Granny Smith (Green apples) and Golden Smoty varieties also brown less. The Golden Delicious (Yellow apples) is average, while Red Delicious (Red apples) tends to brown the most."

Store Apples Properly. The best way to store apples (after using one of the preservation methods above) is to place the slices in a ziplock bag. Seal the bag three-quarters of the way and then suck the air out before sealing it completely. Store the bag of apples in the refrigerator until you're ready to eat or use them. The apple slices will stay fresh and crisp as if they were just cut.

Use a Clean, High-Quality Knife. If your knife is old, it may have been corroded by organic acids, leaving rust stains on the apple slices. These rust stains can accelerate the oxidation process, causing the apples to brown faster. That’s why it’s important to use a clean, high-quality knife to help slow down the oxidation process.

Hide the color of the bruise. If it’s too late to prevent your apple from browning, you can mask the discoloration by dusting a bit of cinnamon over the cut surface. The flavor of cinnamon will add a unique taste to the apple, while its reddish-brown hue will conceal the browning. Cinnamon also contains mild antioxidants, so sprinkling some will help prevent the apple from turning brown further.

These methods can be used for other fruits as well. The techniques above are not limited to apples; they can be applied to any fruit that tends to brown when cut, such as bananas, pears, peaches, and avocados.

• No method can stop browning indefinitely, but they can all keep apples from browning for several hours, such as when you’re preparing them for a fruit platter with cheese.
• The same methods are effective for potatoes, as they operate on the same principle.

• Be cautious when using a knife to avoid cutting your hand.
• Chew your apple carefully to prevent choking.
• If you accidentally swallow the apple seed, there's no need to induce vomiting or call a doctor.
• Do not eat the core of the apple.
