How to judge potatoes with high alkaloid content

In both cases, the alkaloid content in potatoes is higher. One is the green part of the epidermis. The second is the sprout eye of the sprouted potato and its vicinity.

The alkaloid in potatoes is called solanine, also known as potato toxin, which is a toxic glycoside alkaloid, which is a toxic substance in potatoes. This substance can be soluble in water, corrosive and hemolytic, but can be decomposed and destroyed when heated with acetic acid.

The content of solanine in mature potatoes is generally about 10 mg per 100 grams of potatoes and does not cause poisoning.

However, when potatoes are exposed to sunlight, the skin will turn green, and the solanine content in this part will increase significantly. When the potatoes sprout, near the eye of the sprouts, the amount of solanine also increases dramatically, possibly as high as 500 milligrams per 100 grams, which can be enough to kill a person if consumed in large quantities.

When eating potatoes, one must peel off the green part of the skin, and the other is that if it has sprouted, the bud eye and the nearby part must be removed, and then put it in water to soak for a few minutes to let the possible residual solanine dissolve into the water before eating.

If the potatoes are basically green, or if there are more and longer sprouts, it is best not to eat them.

Solatelin is ubiquitous in Solanaceae plants such as potatoes, eggplants, tomatoes, etc. These vegetables are very low in solanine when ripe, so they can be eaten with confidence. It is better not to eat unripe.

Alkaloids generally have a special taste, such as bitter, or hemp. Generally, sprouted potatoes or potatoes that turn green after a long time of light exposure have a higher alkaloid content, and it is not recommended to eat, and the alkaloids here mainly refer to solanine.

Peel the skin, remove the bud eyes, and soak in water. Acetic acid is then added when cooking,,, acetic acid is heated together with solanine, which can destroy the structure of solanine.

Potato peels contain "glycoalkaloids", which can cause poisoning when they enter the human body in certain amounts. In normal tubers, glycoalkaloids are mainly concentrated in the subcutaneous millimeters of potatoes, and the outer skin contains 30% 80% glycoalkaloids.

Acute poisoning symptoms occur when ingested in excess of milligrams of glycoalkaloids per kilogram of body weight in humans. Symptoms can occur within a few minutes to two days after ingestion of toxic potatoes, and the incubation period is generally longer in more severe cases. Symptoms of mild poisoning include acute gastrointestinal upset with diarrhea, vomiting, and severe abdominal pain.

Glyco-formulated alkaloids are very heat-resistant, and will only begin to decompose at temperatures as high as 230 to 280, and the process of frying and cooking cannot greatly reduce their content and cause damage to the glycoalkaloids. Therefore, before cooking, potatoes must be peeled first, and not peeled after cooking; If the potato tastes bitter, it should be thrown away immediately, because the bitterness is due to the high solanine content.

Carrot skin is toxin-free and highly nutritious, so you don't need to peel it.

Can't eat.

Potato peels contain "glycoalkaloids", which may be poisoned after accumulating too much in the body, so we should try to peel the potatoes when steaming.

Because it is a chronic poisoning, it is temporarily asymptomatic or the symptoms are not obvious, and it often does not attract attention, but the harm to the body is great. In particular, potatoes with sprouts and blue skin are higher in toxins and should be absolutely forbidden to eat.

In addition, some people like to roast beef with potatoes with skin, and potatoes with skin still retain glycoalkaloids even after cooking! Even if you peel and eat it after cooking, toxic substances will seep into the potatoes and cause food poisoning.

The stems and leaves of the potato plant are poisonous, and even the potatoes themselves are poisonous. If you look closely at potatoes, you may notice that some potatoes are slightly greenish due to the toxicity of glycoalkaloids.

Potato skin can not be eaten: 1. Potato skin can remove tea stains.

Potato skin can remove the residual tea stains on the human tea set, because the potato skin contains some starch that can allow many substances in the tea stain to absorb its surface, you can use the potato skin to wipe the tea set directly when cleaning, and then rinse it with water, you can easily remove the tea stains, so that the tea set becomes clean as new.

2. Potato skin can be cleaned with stainless steel.

Now there are more and more stainless steel supplies in the family, but after a long time, a large number of stains will remain on the surface of these stainless steel appliances, and they can not be washed off.

3. Potato skin can reduce inflammation and relieve pain.

Anti-inflammatory and analgesic is also one of the important effects of potato skin, when the human body appears swelling and pain, you can directly apply the potato skin to the swollen and painful parts, and change it several times a day, which can quickly reduce the symptoms of swelling and pain. In addition, potato skin can also remove acne, usually after acne on the face, you can directly apply potato skin patch, so that the acne can disappear quickly.

Potato skins are not to be eaten, and potatoes contain a substance called solanine to resist pests and diseases. The content of solanine in potato peels is high, and it can cause poisoning after accumulating in a certain amount in the body. In particular, potatoes with green skin and sprouted potatoes have a higher content of solanine, and excessive consumption can cause a series of gastrointestinal reactions such as nausea and vomiting.

Therefore, potatoes must be peeled and cooked when consumed.

Potatoes contain 2 times more vitamins than carrots, 3 times more Chinese cabbage, and 4 times more vitamins than tomatoes, and the vitamin C content is the highest among vegetables. Experts have found that in the former Soviet Union, Bulgaria, Ecuador and other countries are famous for their longevity, the staple food of people is the potato. In addition to protein, potatoes are also rich in carbohydrates, up to grams per 100 grams, and rich in vitamin C, vitamin A, vitamin B1B2 and minerals such as calcium, phosphorus, and iron.

It also contains vitamin B6, which has the effect of preventing arteriosclerosis. Therefore, regular consumption of potatoes can reduce the incidence of cerebral hemorrhage. Potatoes are rich in potassium, containing 502 mg in 100 grams, and are known as high-potassium vegetables.

Potassium in the human body can strengthen the excitability of muscles, maintain the rhythm of the heartbeat, and have a protective effect on the myocardium. Potassium is the nemesis of sodium, which can prevent the increase in blood pressure caused by high salt intake, and has a significant antihypertensive effect.

In fact, the skin of potatoes can be eaten, mainly because they are afraid of being dirty and have a bad taste, so most of the methods are to cut them off. In fact, potato skin has other effects: potato is Ganping, which has the effects of clearing heat and detoxifying, strengthening the spleen and stomach, relieving dampness and itching, and reducing inflammation and pain.

When using, use potato skins, boil the potato skins in boiling water for about 20 minutes, peel the potato skins of the same size on the wound, apply them to the wound, fix them externally with bandages, and use them for a week to see the effect. Suitable for superficial and small burns only. Peel the potatoes skillfully:

1. The skin of the bean is difficult to peel, but it has a thin skin, and it can be poured with water under the faucet, and wiped with a steel wool ball for washing, and the skin can be wiped off soon. 2. First use a knife to draw a circle around the waist of the washed potatoes, the potato skin is not thick, only need to be shallow, and then draw a circle around the longitudinal direction; After putting it in the pot to steam or boil, immediately put it in clean water to cool quickly, and after 10 seconds, the potato skin has burst open, and the skin can be peeled smoothly. You can also peel sweet potatoes and taro with this method.

3. Due to the uneven surface of the potatoes, they are often cut off with the belt meat when they are shaved, which is very wasteful. If you boil the potatoes in boiling water and then peel them directly by hand, you can quickly remove the skin, which is not only labor-saving, but also smooth, and after cooking, the taste is more luscious. 4. Boiling with a rapid fire will make the outer layer rotten and the inner layer raw.

After the potatoes with the skin are cooked, they are first poured with cold water to make it easier to peel the potatoes. Suddenly, I ate it all

Potato skins contain "glycoalkaloids", which accumulate in the body in a certain amount and cause poisoning. Because the poisoning caused by it is chronic and the symptoms are not obvious, it is often overlooked.

Potatoes grow in the ground for a year, bacteria or something are on the skin, and potatoes should be eaten with the skin removed, so they should be healthier.

I can eat it. Sprouted potatoes are best left uneaten. Potato peels are poisonous.

In fact, you don't need to peel potatoes at all. Potato skins are safe and nutritious, rich in dietary fiber that increases satiety and potassium that helps lower blood pressure. Studies have shown that the amount of vitamins that cling to the bottom of the potato skin is up to 80%, which is much higher than the meat inside the potato.

Baked potatoes and stewed potatoes can be eaten with the skin. Some people think that if the skin of the potato turns green, they should peel off the skin before eating.

It is better not to eat it, the soil scalp is poisonous.

Potato peels are actually poisonous? Don't eat it! Steaming doesn't work either!

You can eat it, some dishes in Europe and the United States are eaten with potato skins, just wash them.

Not good. Potatoes, especially potatoes, contain a substance called alkaloids, which are toxic substances, and the human body ingests a large amount of alkaloids, which can cause poisoning, nausea, diarrhea and other reactions. The alkaloids in potatoes are steroid glycoside alkaloids, mainly solanine and cocoline.

Its structure is similar to that of human steroid hormones, such as androgens, estrogen, progesterone and other sex hormones. According to foreign reports, the freshly harvested potato alkaloids are 20 80 mg per kilogram, and after a period of storage, they rise to 75 114 mg. The alkaloid content of sprouted or moldy potatoes will increase further.

This toxic compound is higher in potato skins, so be sure to peel them when eating, especially peeling off those that have turned green. In addition, sprouted potatoes are more poisonous, so be sure to dig out the sprouts and sprout roots when eating, and soak them in clean water, and stew them over high heat. In addition, if pregnant women regularly consume potatoes with high alkaloid content, they may accumulate in the body and cause fetal malformations.

Of course, there are considerable individual differences in people, and not everyone will have abnormalities after eating potatoes, but it is better for pregnant women not to eat or eat less potatoes, especially potatoes that have been stored for a long time and sprouted, which is especially important for women in the first trimester.
