1, germinated potatoes can't be eaten without buds. Potatoes will produce toxic substances after germination. This substance is called "Solanum nigrum", and most of it accumulates in the germination position. Potatoes can be eaten if they germinate only slightly and the other parts of the surface are not rotted and deteriorated. At this time, there are fewer toxic components, which will not lead to poisoning after eating. However, if potatoes not only germinate, but also grow black spots and rot, they can't be eaten even if the buds are removed. At this time, the toxin of Solanum nigrum may have penetrated into the whole fruit, and there is a risk of edible oil poisoning.

2, how to keep potatoes from sprouting, black plastic bags, first prepare a black plastic bag, then put potatoes in black plastic bags, and tie them, and store them in a cool and ventilated place without sprouting. Black plastic bags have the functions of heat absorption and shading.

3, box storage, box storage is suitable for the city, put the carton or wooden box in the corner, the bottom of the box pad 15 cm high wood or brick to prevent the bottom of the box from being wet, put the potatoes in the box, cover with 15 cm thick wet black soil, and keep fresh, not spicy and slow to germinate.

4. Put apples and potatoes in a fresh-keeping bag with an apple inside. The ratio of potatoes to apples is generally 10: 1. The ethylene released by apples can only delay the germination of potatoes, but can't completely prevent them from sprouting. Generally, potatoes can be successfully preserved for about 2 months by the above methods, but not for a long time.

5. Place in a ventilated place and pile potatoes in baskets or ventilated boxes. Spread a newspaper between each layer of potatoes and cover the top layer of potatoes with newspaper. Newspapers can protect potatoes from the sun Sunlight will make potatoes green and inedible. Sunlight can also germinate potatoes and shorten storage time.
