Why do some potatoes get poisoned when eaten?

Poisonous potatoes are supposed to be sprouted potatoes that turn green on the surface and the toxic substance inside is solanine.

Solanin is the main ** The toxic substance of sprouted potatoes is solanine (solanen), also known as diosolin, which is a toxic glycoside alkaloid. This alkaloid is not a single component, mainly two different glycoside alkaloids, sola-nine and chaconine, which are composed of solanidine as an aglycone. The content of solanine in each part of potato varied greatly, with 0 25 in green leaves, 0 5 in buds, 0 73 in flowers, 1 0 in fruits, 0 004 in mature roots, and 0 01 in skin.

Only trace amounts of solanine are contained in intact and well-behaved potato pieces, and feeding them to livestock generally does not cause poisoning. Solanine can be destroyed when heated in acetic acid. Shaanxi Guanzhong folk vinegar artichoke is a home-cooked dish, which not only tastes fragrant and delicious, but also destroys its toxins during the cooking process.

When the potato is germinated or the flesh turns green and purple due to improper storage, the content of solanine is significantly increased, for example, the sprouted potato pieces can be increased from the normal 0 004 to 0 08, an increase of 20 times; The intra-bud increased from 0 5 to 4 76, an increase of nearly 10 times. The moldy potato pieces can reach 0 58 -1 84, which is increased by 145-460 times; Storing for too long can also increase the number of toxins, which can be increased to 0 11 in July of the following year and to 1 30 after one and a half years of storage.

Eating a very small amount of solanine may not be obvious to the human body, but if you eat 200 mg of solanine at a time (about half a tael of potatoes that have turned green and sprouted), you can get sick after 15 minutes to 3 hours. The earliest symptoms are itching in the mouth and throat, pain in the upper abdomen, and nausea, vomiting, diarrhea and other symptoms, the symptoms are mild, after 1 2 hours will be healed by their own detoxification function, if you eat 300 400 mg or more solanine, the symptoms will be very severe, manifested as increased body temperature and repeated vomiting and loss of water, as well as dilated pupils, photophobia, tinnitus, convulsions, dyspnea, blood pressure drop, very few people can die due to respiratory paralysis. Therefore, patients with severe symptoms should be sent to the hospital as soon as possible**.

The extraction rate and ** rate of solanine extracted from potatoes extracted by ethanol method, ethanol-acetic acid method and mixed solvent method were determined by ultraviolet colorimetric method, and the results showed that the extraction rate and ** rate of solanine extracted by ethanol method, ethanol-acetic acid method and mixed solvent method were the highest, which were 100 and the solanine extracted by ethanol method, ethanol-acetic acid method and mixed solvent method were quantitatively determined by liquid chromatography-mass spectrometry (LC/MS) method, respectively. The results showed that the ethanol-acetic acid method was the best method for the extraction of solanine.

Therefore, when eating potatoes, if you find that the potatoes are green, it is best to throw them away, or you should peel off all the green colors and cook them thoroughly before eating.

Yes, but not with beef. The wrong diet can lead to poisoning!!

The potatoes are blue and cannot be eaten. It's going to be poisoned.

Of course, potatoes contain solanine. The toxic ingredient is solanine (C45H73O15N), also known as potato toxin, which is a weakly alkaline glycoside alkaloid, also known as solanine, soluble in water, easy to decompose in case of acetic acid, and can also detoxify when heated and boiled thoroughly. Solatelin is corrosive, hemolytic, and has a paralyzing effect on the motor center and respiratory center.

Each 100g of potatoes contains solanine glycosides only 5 10mg; The solanine content of unripe, bruised-skinned potatoes or sprouted potatoes increased to 25 60 mg, and even as high as 430 mg. Therefore, eating large quantities of immature or sprouted potatoes can cause acute poisoning.

Eating raw potatoes may cause poisoning.

If you feel unwell after eating uncooked potatoes, you can go to the hospital to take symptomatic treatment** to promote the metabolism of endotoxins. In addition, sprouted pure liquid potatoes contain more solanine, so it is recommended not to eat them.

Potatoes contain a lot of starch, can provide rich calories for the human body, and rich in protein, amino acids and a variety of vitamins, minerals, especially its vitamin content is the most complete of all food crops, in Europe and the United States, especially North America, potatoes have long become the second staple food.

Since potatoes contain alkaloids in them, if they are not fried, they can cause digestive discomfort. In addition, potatoes are not easily digested if they are not fried. In normal times, for this starchy food, it is best to fry a little, which is conducive to the digestion and absorption of food.

Can you eat potatoes if they sprout?

It is best not to eat potatoes when they sprout, and when eating potatoes, they should be injected with lead and observe that once they are found to be sprouting, this kind of potatoes cannot be eaten. Since potatoes sprout, potatoes produce a solanine, a toxic substance that can cause food poisoning if eaten carelessly.

Summary. Kiss 3 Hello! Glad to answer this question for you :

Raw potatoes will not be poisoned if eaten. But there may be uncomfortable symptoms, this is because the gastrointestinal intolerance of Chinese to raw food, so try not to eat raw potatoes. In addition, poisoning occurs only when you eat sprouted potatoes, mainly due to spoilage of potatoes.

Kiss 3 Hello! I'm glad to answer this question for you. 晌萌: Raw potatoes will not be poisoned if eaten.

But there may be uncomfortable symptoms, this is because the gastrointestinal intolerance of Chinese people to eat raw potatoes, so try not to eat raw potatoes. In addition, eating sprouted pancakes will cause poisoning, mainly due to the spoilage of potatoes.

In addition, it is not recommended to kiss 3 raw beans, first of all, potatoes are a vegetable rich in starch, including a lot of resistant starch, starch grains are not easy to break when eating potatoes raw, not only many nutrients are not digested and absorbed by the jujube family, but also because of indigestion to cause bloating, diarrhea and other symptoms.

It is best not to eat it raw. Potatoes contain some toxic alkaloids, mainly solanine and chochomycoline, but generally after 170 years of high temperature cooking, the toxic substances will decompose. Wild potatoes are highly toxic, and solanine poisoning can cause headaches, diarrhea, convulsions, coma, and even death.

However, the toxicity of generally cultivated potatoes is very low, and there are very few incidents of potato poisoning.

Eating potatoes can be poisoned" may have been known for a long time, but most people can't say why they can't say why they will be poisoned in order to investigate and dismantle it. Fresh potatoes contain trace amounts of solanine, which is not harmful to the human body, but during the storage of potatoes, the solanine content gradually increases, when the potatoes become black-green cracked dates or sprout, the solanine in them increases significantly, and the solanine content of the young shoots and bud eyes is as high, and people can cause food poisoning if they eat solanine grams.
