Use lemon juice. Apples are darkened by an enzyme present in the fruit that reacts with the oxygen in the air. This process is called “oxidation”. Lemon juice can prevent oxidation because it contains citric acid, which is a very effective antioxidant. You can use fresh lemon or pre-mixed lemonade, this is best for sweet apples because fresh lemon juice can make apples sour. To use lemon juice to prevent apples from darkening, you can use one of two ways:

  • You can also use lemon to help prevent your apples from darkening by soaking apple slices in a bowl of cold water mixed with lemon juice. You should mix in a ratio of one teaspoon of lemon juice to one cup of water. You just need to soak the apples for 3-5 minutes, then take them out and wash them. [1] X Research Source
  • Lemon nuggets can also be used instead of regular lemon juice because limes also contain citric acid, which is essential for the antioxidant process. Pineapple juice can also be a good alternative.
Use salt. Salt is a natural preservative and is very effective in keeping apple pieces from turning brown. Sprinkle salt over the apple plate with a spoon. To make sure your apples don’t taste too salty, don’t use more than a teaspoon of salt. This way can keep the apple pieces from oxidizing for quite a long time. [1] X Research Source

  • Don’t worry about the apples being salty – as long as you don’t use too much salt, the apple slices will still taste normal.

Use carbonated drinks. Carbonated drinks also contain citric acid, which helps keep your apple pieces from turning brown. Lemon soda and ginger ale are two popular drinks you can use to soak your apples.

  • Simply drop the apple pieces into a bowl containing your chosen carbonated water, soak for 3-5 minutes then drain. You can wash them if you want, or just leave them be and enjoy the new flavors infiltrating!
  • Seltzer mineral water (xenxe) is also an option to help you keep the apple slices from browning, so you can give it a try if you have this on hand! [1] X Research Source
Use Fruit-Fresh powder to keep fruit fresh. Fruit-Fresh Powder is a powdered mixture of citric acid and ascorbic acid, specifically designed for the purpose of keeping fruit from darkening. It is said to prevent fruit from darkening for up to 8 hours, and you can buy it in the canning section of most grocers. [2] X Research Source

  • To use Fruit-Fresh powder, all you need to do is sprinkle half a teaspoon of powder on each plate of sliced apples. Make sure the dough evenly coats the surface of the apple pieces. [2] X Research Source
Blanch the apple. You can blanch apple pieces to prevent them from browning, and blanch apples to deactivate the enzymes in apples, making them unable to catalyze oxygen in the air. [3] X Research Source To blanch apples, simply dip them in warm water for about 5 minutes, then remove and rinse with cold water.

  • You should note that using this method will make the surface layer of the apple pieces soft, when eaten, they will lose their taste. So this method is best suited for apples that you plan to use in cooking or baking. [4] X Research Sources
Cover with food wrap. One simple method you can use to prevent apples from turning brown is to wrap the apple pieces in cling film. This technique works by preventing air from coming into contact with the apple pulp, thereby preventing the apple pulp from oxidizing. Try to wrap the wrap around the apple as tightly as possible and avoid letting any creases in the glossy paper come into contact around the opening of the apple.

  • This method is best used with halved apples rather than small pieces because tightly wrapping a large apple is easier.
  • It should be noted that as long as there is a little air inside the wrapper, the apple will oxidize. Because it is difficult to completely remove air, this method is not the most effective.

Use string to tie. Using an elastic band is a pretty creative, and easy to do, way to prevent your apples from browning, although it can only be used with whole apples that have been cut into pieces, and not peeled. This method works because it doesn’t leave the apple pulp exposed to the air. [5] X Research Sources

  • Simply cut the apple into regular pieces then put them back together like a jigsaw puzzle, to get the same shape as the original apple. Wrap the rubber band around the apple so it will appear as if it hasn’t been cut. [5] X Research Sources
  • This is a good option for those who want to bring pre-cut apples to work or for their kids to bring for their school lunch.

Choose the type of apple you eat wisely. Some apples are more prone to browning than others, so if you’re going to cut apples, choose one that’s less likely to darken. Studies on the ripening process of apples show that: “Arangeh apple variety has the least browning. Granny Smith (Green Apple) and Gpden Smoty varieties also have less browning. Gpden Delicious (Yellow Apple) variety is average. and Red Delicious (Red Apple) is the most bruised variety.”

Store apples properly. The best way to store apples (after using one of the apple preservation methods above) is to place the apple pieces in a ziploc bag, seal three-quarters of the opening, then use The mouth sucks all the air out and then closes the lock. Place the bag of apples in the refrigerator until you want to eat them or use them for something else. Apple slices will always be fresh and crispy like new. [1] X Research Source

Use a clean, good quality knife. If the knife you used to slice apples is old, it may have been corroded by organic acids and left rust marks on the apple. Those rusts can speed up the oxidation process significantly, causing your apples to darken faster. That’s why it’s important to use a clean, high-quality knife in helping you slow down oxidation.
Hides the color of the bruise. If it’s too late to prevent your apple from turning brown, you can hide it by sprinkling a bit of cinnamon on the cut side of the apple. The flavor of cinnamon will help the apple taste more unique, while the reddish-brown color of cinnamon will help cover the color of the bruise. Cinnamon itself also contains mild antioxidants so sprinkling a little cinnamon will help you prevent the apple from browning more. [4] X Research Sources
  • These methods can be used for other fruits as well. The above methods don’t just work for apples, they can be used with any fruit that tends to darken when cut, including bananas, pears, peaches and avocados. [6] X Research Sources
  • Advice

    • Neither method will last forever, but all can help keep apples from browning for a few hours, for example when you want to toss them with cheese on a fruit tray.
    • The above methods also work with potatoes. Because they share the same principle of operation.

    Warning

    • Be careful when using a knife. Avoid cutting your hand.
    • Chew your apples well when eating to avoid choking.

    • “Do not eat” the core of the apple.
