Storage of potatoes is important to minimize solanine formation. Potatoes are cold, dry and dark. As suggested by the NRW Consumer Advice Centre, the optimum temperature is between four and eight degrees. If potatoes are stored above eight degrees, they germinate faster. Below four degrees, starch is converted to sugar and potatoes are sweet. So storage in refrigerator is not recommended. The best storage space, for example, is the basement. If you buy potatoes wrapped in plastic, be sure to remove the potatoes to prevent moisture build-up.

Avoid sprouting potatoes: Ethylene from apples can help

Storing potatoes with apples will do wonders. The ripening gas ethylene, which usually speeds up the ripening process of other fruits or vegetables, is released from the apple. However, for potatoes, ethylene has a portal-like germ-inhibiting effect. utopia.de writes

An apple can be stored with about one to two kilos of potatoes, and the ethylene diffuses automatically. However, apples also need to be changed regularly so that nothing rots. However, consumer center NRW also warns that ethylene can cause potatoes to shrink and lose their aroma. In general, potatoes should not be left for too long.

Sprouted potatoes – so the consumption of the tuber is harmless

Just because potatoes sprout, doesn’t mean you have to throw them away. If you have potatoes with some small sprouts or some green spots, you can still eat them. You should liberally remove these spots and eat potatoes without the skin. Solanine is released in cooking water, so it should not be used.

Do not remove the skin until the potatoes are cooked so that more vitamins are retained. However, as recommended by the Lower Saxony Consumer Advisory Center, children should not eat unpeeled potatoes. With a simple trick, potatoes can be cooked in three minutes. (VK)
