However, the cut apples always turn yellow, which makes people very distressed. Let me teach you how to preserve the cut apples.

How to keep cut apples fresh

1. After an apple is cut, it turns yellow because the iron ions in it are oxidized. You should first add some salt to cold water, and then pour the water on the cut surface of the apple. This will effectively prevent the apple from turning yellow and achieve the purpose of preserving freshness.

2. Add a few drops of lemon juice on the cut surface of the apple. This will not only prevent the cut surface from turning yellow but also keep the original taste of the apple. You don’t need to wash it when you eat it. It is convenient and effective.

3. Soak the cut apples in cold water. This will not only prevent discoloration but also make the apples crisper, sweeter and more refreshing.

4. Wrap the cut apples with a layer of plastic wrap to prevent the oxidizable substances in them from being oxidized by the air. Placing them in a cool place can effectively prevent them from turning yellow and achieve the purpose of preserving freshness.

5. Put the cut apples into a vacuum bag to isolate the air, which can extend the shelf life. You can use a vacuum cleaner or your mouth to create a vacuum environment.
