Can sprouted potatoes be eaten? Some experts once said that germinated potatoes are easy to cause human poisoning, so it is not recommended to eat them. Potato protein has a high nutritional value, and its quality is equivalent to that of egg protein. It is easy to digest and absorb, which is better than other crops. And potato protein contains 18 kinds of amino acids, including all kinds of essential amino acids that human body can't synthesize.
It can be used as a main food as well as a stir fry, so it is very popular, especially in the north where the natural environment is bad and there are few kinds of vegetables.
But you will find that the potatoes you buy will turn green and sprout if you don't pay attention to them. It's a pity if you throw them away, but you will be afraid if you don't throw them away, because the saying that eating sprouted green potatoes will be poisoned has never stopped.
So what about the facts?
After harvest, the growth process of potatoes has been stopped, and the metabolism has been reduced to the lowest level. Usually we call this period the dormancy period. The dormancy period of potatoes is 2 to 4 months. But if the temperature and light conditions are right, the bud eyes on potatoes will germinate again and enter a new growth period.
In most varieties of potatoes, under the condition of direct sunlight or high temperature, the epidermis will turn green. It is because the starch generating body in potatoes changes into chloroplast, which then produces the accumulation of chlorophyll. Chlorophyll is harmless to human body, but because potatoes turn green, some alkaloids are produced at the same time, especially solanine, also called solanine, which is a kind of toxic alkaloids.
Can't we eat potatoes that sprout or turn green?
It doesn't have to be from life experience or from the scientific point of view of 'let alone dose and talk about toxicity'.
In general, the content of solanine in potatoes is very low. When the content of solanine in green potatoes reaches 10 to 15 mg / 100g fresh weight, people can obviously feel a little bitter. When the content reaches 20 mg / 100g fresh weight, different degrees of poisoning symptoms will appear.
When the degree of green germination of potatoes is not serious, cut off the part of green germination, and then soak it in water for half an hour. In the process of processing, you can boil it, then pour out the boiled water, or add a little vinegar to destroy solanine.
