How to choose potatoes;

If there is no broken skin, try to choose a round one. The rounder the better. The skin must be dry and not blistered, otherwise it will last for a short time.

It tastes bad, too. Don't have buds and greens, that's about it. Potatoes that sprout already contain toxins and are not suitable for eating. If you find that the potato skin turns green, don't eat it even if it is very light green. Because the green of potatoes is a sign of the existence of toxic alkaloids, eating them will be poisoned.

Poor quality potato pieces are small and uneven; There are damaged or moth-eaten holes; The potato pieces wither and become soft, and the potato pieces germinate or turn green; Mixed with more pests and banned potato chips; There is a rotten smell. Potatoes should not have small buds, otherwise it will be harmful to human body. Also, see if the color is fresh. Don't have black parts like bruises. Most of them are bad. Of course, the price is also on the one hand, the real price is the best!
