How does formaldehyde in vegetables come from? Formaldehyde in vegetables can be divided into endogenous and exogenous categories:
1. endogenous formaldehyde
It is produced in the process of biological metabolism and naturally exists in many foods, such as vegetables, mushrooms, fruits, meat, fish and so on. This formaldehyde content is extremely small and basically harmless to the human body.
2. Exogenous formaldehyde
It is caused by improper use in food processing, transportation and sales, and is the main cause of formaldehyde pollution in food. The "formaldehyde cabbage" and "formaldehyde doll dish" that broke out in previous years all belong to this situation.
Vegetable vendors use formaldehyde because spraying diluted formaldehyde on the roots of vegetables can not only reduce the heat and decay of vegetables during long-distance transportation, but also make the roots of vegetables white and clean, which is more popular with buyers.
China's Food Safety Law and Agricultural Products Quality Safety Law clearly stipulate that formaldehyde shall not be used as a processing aid for food production, operation and use. In other words, it is illegal to add formaldehyde to food in any way.
Therefore, "formaldehyde dish" is only an individual phenomenon, and everyone's hanging heart can be put down a little.
Which vegetables may contain formaldehyde 1 and garlic moss?
Garlic moss is an out-of-season vegetable, which ripens in April and May. Then the garlic moss at this time is an anti-season vegetable! In order to prolong its storage time, garlic moss out of season will definitely spray some formaldehyde into it! Therefore, when eating garlic moss, you must not wash it directly with water. It is necessary to use flour or starch to absorb dirt and formaldehyde on the surface of garlic moss to reduce the intake of formaldehyde.
2. Bagged baby tableware
If this kind of bagged baby cabbage is not kept in a bag, it will easily rot for more than 48 hours. So the vegetable vendor finally sprayed some formaldehyde in the big room. Although the amount is not much, it is not good after all. So when you eat this bagged baby dish, remember to rinse it with water for two or three times.
3. Duck blood
Duck blood is the most common dish in daily life, and there are many fake duck blood on the market now. A large amount of formaldehyde is injected into the fake duck blood to cover up the taste of other blood. Are you really at ease to eat a box of duck blood for two dollars?
4, bagged Flammulina velutipes
Flammulina velutipes will not be stored for more than 24 hours if it does not contain formaldehyde when picked. Nowadays, most of the bagged Flammulina velutipes in supermarkets are vegetables containing formaldehyde. Flammulina velutipes itself is not poisonous, but formaldehyde. So it became a rotten dish.
5. Fresh mushrooms
Fresh mushrooms are rich in endogenous formaldehyde. When it is taken off, there are many living things in it, which will produce endogenous formaldehyde. So when we eat this mushroom at home, we must remember to put it in boiling water for 30 seconds in advance. Remove endogenous formaldehyde, so that eating it will not affect your health.
