Yes, if the potato skin is green and germinates, it is mainly solanine produced in the blue bud of the potato. This toxin is soluble in water and not resistant to high temperature. Therefore, in addition to cutting off the buds visible to the naked eye, potatoes with buds should be peeled, or cut into small pieces and soaked in cold water for more than half an hour to dissolve the remaining toxins in water.

When cooking, the toxin can be further destroyed by high temperature, boiling or frying. Finally, we add some vinegar, so that the toxin can hardly be contained and can be eaten safely.

From a nutritional point of view, potatoes have comprehensive nutritional components and reasonable nutritional structure. Potatoes are rich in water, fat and calories per unit volume, and are rich in trace elements necessary for human body, such as potassium, calcium, iron and magnesium, as well as carotene and ascorbic acid that cereals do not have. Potatoes are rich in cellulose, which helps to promote gastrointestinal peristalsis and dredge the intestines.

Potatoes can be stored in the shade at about 5℃ for a long time. Once the temperature is too high, potatoes will sprout or turn green. If you need to keep it for more than two weeks, you can put the potato and the apple together, because the apple will release ethylene, and ethylene will inhibit the cells in the eye of the potato bud from producing auxin, thus reducing its germination.
