As food, whether it is spring, summer, autumn or winter, germination is always related to them.
Sweet potatoes that have been put for a long time will sprout; ginger, onions and garlic that have been bought for a few days will sprout new shoots and "thrive", which is really a little way to do it...
Some people can't remember which sprouted foods can be eaten and which can't be eaten, so the Buddhists eat them all; some people, on the contrary, "would rather kill by mistake than let go" and avoid them all.
Good food, food worries, abandonment of pity, so can sprout food be eaten in the end? Let's take a kitchen adventure today.
First, sprouted, green potatoes are recommended not to eat
potato
As a well-known food on the "sprouted food toxic list", it is almost a household name.
And this "killer", is the potato in the dragon sunflower, the normal potato dragon sunflower content is very low, will not pose a threat to the human body, once germinated, the dragon sunflower will be greatly increased, become a "toxic" killer, even if heating can not be removed.

Green potatoes should also pay attention to the fact that potatoes "wear green hats" are actually a signal of the increase in dragon anthrophyll.
Longkolin is mainly distributed on the green epidermis, if the green part of the epidermis is less, it can indeed be eaten by cutting off the surface. However, it should be known that if you eat 200 mg of longanin (about 50 g of greened, sprouted potatoes) at one time [1], poisoning may occur.
If you can't judge the degree of sprouting and greening of potatoes, it is recommended to throw them away, which is a pity.
Store small tips:
Potatoes are best bought at low temperatures (about 4°C)[2], in a place protected from light, such as a refrigerator freezer.
Small amounts of potatoes can also be placed with apples and bananas, and the ethylene gas released by mature fruits can effectively inhibit the germination rate of potatoes [3].
Second, these foods can be eaten when they sprout, but their nutritional value will be reduced
1. Onion, ginger, garlic
As one of life's regular condiments, onions, ginger and garlic are always in the corner of the kitchen, and once you forget them, they sprout in different ways.
However, for this spicy condiment, germination generally does not produce toxins and does not affect continued consumption. But nutrition will be "discounted" and the taste will become worse, because the newly grown buds absorb their original nutrients, and the ingredients will become dry and weak.
The germination of onions and garlic may surprise your food storehouse, such as finding a pot to keep them in, and soon you may be able to eat your own "green onions" (actually onion seedlings, not other onions) and garlic seedlings.
Ginger can be wrapped in plastic wrap and refrigerated in the refrigerator .[4]
Note: Do not eat rotten ginger, rotten ginger will produce a large number of highly toxic safrole, which can degenerate and necrosis of liver cells, induce liver cancer, esophageal cancer and so on. The "rotten ginger doesn't taste bad" argument is unscientific.
Garlic can be placed in mesh bags and hung in a cool, ventilated place [5].
2, sweet potato taro yam
These belong to the potato class, and the germination process does not produce any harmful ingredients, otherwise how can the sweet potato leaves and taro seedlings used as ingredients be brought to the table?
However, the germination of these potatoes is the same as the germination of ginger and garlic, and the nutrients and moisture will be lost in the process, and the taste will become worse.
It should be noted that before eating, carefully check, sprouted sweet potatoes may be moldy, producing toxins such as sweet potato ketone, sweet potato ketol, etc., if the epidermis is brown, black spots or any signs of mildew, it is recommended to throw it away.
You can use dry paper to separate a small space in a cardboard box, and then put the sweet potatoes in the small compartment of the carton.
Taro and yam are suitable for place in a dry, cool and ventilated place.
3, cabbage small rape radish carrot
These vegetables sprout, do not produce toxic substances, but like onions and garlic, the taste and nutritional value is slightly worse.
When you see the Internet turning cabbage root, radish head, etc. into cute little potted plants, are you also eager to move?
Indeed, as long as these vegetables have the right conditions, they "want to open". If you don't want to eat them and don't want to waste them, it's also good to turn them into eye-catching little green plants.
Third, after these foods germinate, the nutritional value is higher
1. Peanuts
In recent years, peanut sprouting has become popular as a new favorite of sprouts.
Peanut sprouts have a significant increase in vitamin C[6], and antioxidant content such as resveratrol increases [7]. In this way, peanut sprouts as an ingredient choice are still good.
But even so, the germination of home peanuts is not recommended.
The peanuts stored in their homes germinate coldly, most likely because the shell of the peanuts has been damaged, and the environment in which the peanuts sprout is likely to be a hotbed suitable for mold generation, which increases the chance of contracting aflatoxin (Class I carcinogen).
Therefore, once you perceive that "it is not good", the peanuts sprouted at home are still recommended to be thrown away, and if you really want to eat peanut sprouts, you should go to the supermarket and the wet market to buy it.
2, soybeans, mung beans, peas
These beans, which we commonly find, are themselves excellent ingredients; and sprouts that become sprouts after germination have higher nutritional value.
In the case of soybean sprouts, fat and reducing sugars decreased compared to soybean sprouts, while vitamin A, vitamin C, riboflavin, niacin, and isoflavones increased [8].
Moreover, after the beans sprout, some proteins will also be decomposed into various amino acids needed by the human body, and the sprouts are more delicious and delicate, and more suitable for people with poor digestive function.
Pea sprouts, on the other hand, are "excellent benxiu", and the germinated pea carotene (2700 μg/100 g) is 27 times more than the melons and fruits and vegetables we often eat (usually less than 100 μg/100 g) [6].
However, these sprouts are the same as peanuts, and homemade must ensure the safety of the ingredients and avoid mildew.
Whether sprouted food can be eaten, today has helped everyone to clarify, I hope you eat delicious, healthy and safe!
