What toxic ingredients are common in life?

In our understanding, there is a great difference between poison and food, but in life, many foods we often come into contact with are toxic substances and need special treatment before they can be used.

Toxic food

Day lily, also known as the girl without worry, is widely distributed in China, and is liked by many people because of its crisp taste and rich nutrition. Although it is delicious on the table, fresh day lily contains toxic alkaloids. People used to think that this alkaloid was colchicine, but now it is not.

Nevertheless, if the day lily is not handled properly, it may cause food poisoning, nausea, vomiting and other symptoms, and even death.

However, the toxicity of day lily is not difficult to deal with, as long as it is cleaned before eating and the stamens are removed, because the stamens contain the most toxins. After that, soak for several hours, and then remove the toxins from the food after it is fully fried. If you are worried about poisoning caused by improper handling, you can buy dried daylily to eat. Dry day lily has destroyed alkaloids in the production process, so you don't have to worry about poisoning when eating.

In addition, there is also a kind of delicious food in Yunnan that is said to be the best in the world: wild mushrooms. However, there are many kinds of wild fungi, and there are many differences in appearance. Some are non-toxic and some are toxic. This poisonous mushroom can completely remove toxins after certain treatment.

However, due to improper disposal, and some people can't accurately tell whether the collected mushrooms are poisonous, many local people will be poisoned by eating wild mushrooms when a large number of wild mushrooms are on the market every spring. Therefore, if you want to eat wild mushrooms in Yunnan, there is a saying that you should be familiar with the varieties and methods of wild mushrooms and the way to the hospital.

In recent years, whenever a large number of wild mushrooms are on the market, the local government will also tell local people not to collect wild mushrooms privately through short messages and TV programs, so the number of wild mushroom poisoning incidents has also decreased in recent years.

There are also some places abroad that eat poisonous food, such as cassava, but they will be specially treated before eating to ensure that they will not cause poisoning.

In addition to food itself containing toxins, there are some foods that are originally non-toxic, but improper placement will cause human poisoning.

Improper preservation leads to food poisoning.

The most common spoiled food is germinated potato, which contains solanine and is very toxic. When the toxin of solanine reaches about 0. 1 g per catty, people will be poisoned, but the symptoms are mild, mostly dizziness and nausea. And it won't take long to recover.

But when the content of Solanum nigrum in potatoes reaches 2.5 grams per catty, potatoes at this time will pose a life threat to people.

However, if the potatoes at home have just sprouted, cutting off the sprouted and surrounding parts in time and soaking them in clear water can remove some toxicity. This is because Solanum nigrum is soluble in water, and in the newly germinated potatoes, the toxin is concentrated around the germination and has not spread to the surrounding. In addition, high temperature and vinegar can destroy some toxicity, so when the germination area of potato is not very large, it can still be used after treatment.

In daily life, the most perishable and toxic foods are nothing more than edible fungi and tremella. Under normal circumstances, the fungus or tremella we buy is dry, so we should soak it before eating. Because of the high nutritional value of auricularia auricula and tremella, microorganisms will multiply rapidly, leading to food deterioration and poisoning.

Pseudomonas cocoanum is a very common microorganism in life, but it will not cause us poisoning, because it requires high environment, and dry environment and acidic environment will kill them. Moreover, it is hooliganism to talk about toxicity without dosage. Even if the food contains a small amount of Pseudomonas cocoanum, it will not affect the human body.

Auricularia auricula and Tremella fuciformis have high nutritional content and are suitable for the reproduction and survival of Pseudomonas cocoanum. Therefore, when auricularia auricula or tremella fuciformis is soaked for a long time, the toxicity of food will become very high, even leading to human death.

It is dangerous to soak fungus and tremella for more than 4 hours. When the foaming time exceeds 1 day, the probability of human poisoning death will also increase greatly.

Of course, spoiled food itself is toxic. No matter what food is spoiled, it should be thrown away immediately and cannot be eaten.

abstract

Sometimes poison and food are far apart, but sometimes they are the same creature. Even poison can be turned into food, such as day lily, mushrooms and so on, as long as it is handled properly in the production process. However, if some foods are not properly preserved, they will also become poisons, such as fungus. If you are worried about food poisoning, you can try to reduce the frequency of eating these foods or not eat them at all.
