Formaldehyde, a lot of people talk about it, the body inhaling too much formaldehyde will damage the body’s immunity, and it will also increase the risk of leukemia, which will slowly damage the body. There are a lot of sayings on the Internet that “vegetables bound with tape exceed the standard by 10 times”, saying that eating vegetables bound with tape will cause poisoning and cause cancer.
During the epidemic, everyone stocked up a lot of vegetables, right? Can’t eat any vegetables tied with tape? Let me tell you the answer today.
The degree of connection between tape and formaldehyde is not high. According to the national standard, the determination of formaldehyde composition requires Soak in 4% acetic acid at 60°C for 2 hours.
The area of the tape used in the vegetables sold in the market is much less than 1 square decimeter, and the contact temperature is much lower than 60 ℃ in the experiment , and the acidic environment required by the experimental conditions will not occur. Test data from third-party research institutions show that formaldehyde has not been detected in vegetable samples.
So the tape used for bundling vegetables will basically not harm your health, and there is no need to worry about it.
Some foods (aquatic products, milk, vegetables, fruits, etc.) naturally contain trace amounts of formaldehyde, and different foods have different mechanisms for producing formaldehyde.
For example, there is a “trimethylamine oxide” substance in fish meat, which will decompose to produce a small amount of formaldehyde under the action of biological enzymes or microorganisms , Some seafood such as fresh squid contain about 20 mg of formaldehyde per kilogram.
Fruits and vegetables will produce trace amounts of formaldehyde in the process of cellular metabolism through respiration under the influence of storage environment and storage time.
Formaldehyde is easily soluble in water, and formaldehyde in food can be washed or soaked with water to remove part of formaldehyde; secondly, formaldehyde is a volatile The organic compounds are easily volatilized at room temperature. If the ingredients are cooked or fried for a long time, that is, after high temperature treatment, the formaldehyde in the food can be completely removed.
Mother saidFinally, I will draw a key point for you:
< span>1. The tape is indeed a gray area, and “food-grade” tape does not exist yet.
2. Authoritative tests show that the formaldehyde residue in the tape is not as terrible as legends. Moreover, there is currently no standard limit for formaldehyde residues in food, and the statement in the news that “formaldehyde exceeds 10 times the standard” is unreliable.
3. Natural formaldehyde already exists in food, and formaldehyde is highly water-soluble and volatile. If you are too worried about tape dishes, just process or dispose of them.
If you buy vegetables bound with tape, it is best to remove the tape as soon as possible, so that the peeled vegetables can be in contact with the tape. Part of it is directly peeled, or the vegetables are soaked in warm water or light salt water before eating, or simply remove the contact part, so as to ensure health!
However, for the sake of safety, it is recommended that you try to choose vegetables that are not tied with self-adhesive tape when buying vegetables.
