“Do not buy vegetables wrapped with tape. Formaldehyde exceeding the standard ten times will lead to leukemia…”

Ms. Zhang this morning I bought a bundle of lettuce from the supermarket and went home with a circle of green tape on it. Unexpectedly, my mother-in-law changed her face when she saw this tape, saying that there is something wrong with this dish, and that it contains formaldehyde and will cause cancer.

“But aren’t all the vegetables in the supermarket wrapped with tape? Could there be any problem?” Ms. Zhang wondered.

“It’s been said on the Internet that there is something wrong with this dish, I would rather believe it than not!” The mother-in-law said with a serious face, and she said that she just bought it. The dishes were thrown away.

Looking at the dish that was thrown away, Ms. Zhang was very distressed, but she was afraid that it really contained formaldehyde. After all, almost everyone knew the name of formaldehyde. Do vegetables wrapped in tape really contain formaldehyde? Can I still eat it later?

1. Are vegetables wrapped with tape poisonous? Formaldehyde exceeds the standard ten times?

Why does the tape contain formaldehyde? Tapes are usually composed of an adhesive and a substrate.Some adhesives use formaldehyde as an auxiliary material in the production process, if not fully reacted A small amount of formaldehyde may remain, and many people worry about formaldehyde on the tape wrapped around vegetables when they buy vegetables.

In response to your concerns, in 2016, Shenzhen Quality Inspection Institute and Shenzhen Food and Drug Administration strong>In different supermarkets, 11 vegetables bound with tape were sampled for formaldehyde residue detection.It was found that no formaldehyde was detected in all vegetable samples, while only 0.13-0.19 mg/square decimeter of formaldehyde was detected in the tape, which is a very small amount.

Jiang Limao, a professor-level senior engineer in the quality and safety risk assessment of agricultural product packaging materials of the Ministry of Agriculture, introduced that there is no need to worry too much. There are strict standards and regulations for materials that come into contact with food. According to the relevant provisions of the national standard GB 9685-2008 “Hygienic Standards for the Use of Additives for Food Containers and Packaging Materials”, the maximum formaldehyde residue used for food contact should not exceed 15 mg/kg , the tape that meets the national standard will not affect the quality of vegetables.

Second, take stock of the popular “formaldehyde dishes” on the Internet, don’t be fooled again

It is rumored that several vegetables contain formaldehyde, which can cause cancer when eaten, but this is not true.

1. Baby Cabbage

There are rumors that Baby Cabbage will soak in formaldehyde and eat it Can cause cancer. Eating baby cabbage bought from regular channels without adding illegal substances will not cause cancer. Even if the baby cabbage is dipped in formaldehyde, but formaldehyde is soluble in water and volatile, as long as it is fully cleaned, it can be removed.

2. White tofu

The color of tofu is actually affected by Influenced by factors such as the type of raw materials and coagulants, formaldehyde must not be added to white tofu, because tofu can also become very strong under normal circumstances. It is unreasonable to identify whether tofu contains formaldehyde by color.

Third, find out those hidden “big formaldehyde owners”

Of course, there are indeed foods that are easy to hide more formaldehyde in our lives. For example, these two foods require us to be vigilant:

1. “Blooming” hairtail

Some unscrupulous merchants will add formaldehyde to hairtail to keep it fresh, prolong the shelf life, and make hairtail more elastic and brighter in color. Gong Jianzhuang, Deputy Chief Physician of the Department of Gastroenterology, Zhengzhou Central Hospital Affiliated to Zhengzhou Universityexplains that if the hairtail will burst and “bloom” when fried It may be related to formaldehyde, because when hairtail is treated with formaldehyde, due to the different concentrations of formaldehyde on the surface and inside of the fish, the degree of denaturation is different , once suddenly encountering high temperature, it is easy to burst, and it looks like “blooming”.

2. Extra crispy chicken feet with pickled peppers

normally cooked chicken feet The color of the back skin is natural, and the skin is tough and not easy to tear off, if after breaking the chicken feet The skin is thin, crunchy, and easily torn off, indicating that the chicken feet may have been soaked in formaldehyde.

4. How to eat less formaldehyde dishes?

1. Avoid from the source
