How to keep an apple from changing color

Apple is one of the most popular fruits in life, and people like to peel the apple before eating it, but many people find that the apple changes color soon after peeling, which makes people very annoyed. How can we prevent the apple from changing color? The following editor will teach you a few tricks.

How to keep an apple from changing color

1. Soak in clean water

Normally, apples change color after being peeled. This is mostly due to an oxidation reaction when the phenolic compounds in the apples come into contact with oxygen in the air. If you want to avoid the apples from changing color, you can soak the apples directly in clean water. If you add a small amount of salt to the water, it will make the color of the apples more attractive.

2. Use lemon juice to preserve the color of apples

Lemon juice can also protect apples from changing color. The best way is to apply some lemon juice directly on the knife when cutting or peeling apples. This way, the cut apples will not change color and will make the apples taste more tempting.

3. Use plastic wrap to protect the apple from changing color

Apples change color when the flesh comes into contact with oxygen in the air. In other words, if you just avoid contact between the apples and the air, the apples will not change color. The best way is to wrap the apples with plastic wrap. This way, the apples will not change color even if they are not stored for more than ten hours. If you put apples wrapped in plastic wrap in the refrigerator to keep them fresh, they can be stored for three to five days without spoiling or changing color.
