1, apple method. Apple will release ethylene gas, which can delay the germination of potatoes, so it can play a better preservation effect. You can put some apples next to the potatoes. But apples can't completely prevent potatoes from sprouting, so the storage time of potatoes should not exceed 2 months.

2. Black plastic bag method. Another way to prevent potatoes from sprouting is to use the principle of avoiding light. Without photosynthesis, potatoes can't sprout new buds. Therefore, it is best to keep potatoes in black sealed bags, which can prolong the shelf life of potatoes.

Extended data:

1, the potato skin turns green and can't be eaten.

If the potato skin turns green, it means that the solanine content is high. Be careful when eating this kind of potato, not only peel it, but also cut off more pulp and completely remove the green part. If the green part of potato skin is large or has sprouted, don't eat such potatoes, otherwise it will easily lead to food poisoning.

2. You can't eat potatoes when they sprout.

When potatoes turn green, germinate or rot, the content of solanine will increase greatly. Eating a very small amount of Solanum nigrum is not necessarily harmful to human body, but if you eat 0.2-0.4 grams of Solanum nigrum at a time, it may cause poisoning.
