I heard that the tape for tying vegetables is poisonous? Can I buy vegetables with tape?

In the supermarket, customers are shopping for small bundles of vegetables

▼

This kind of bundled vegetables is very common in supermarkets and farmers' markets. It is convenient for people to buy, and businesses also use this method to prevent "smart" customers from picking too much.

In the past, straw rope was often used to bind vegetables. In recent years, vegetables bound with colorful tape have become more and more common.

Compared with straw rope, tape is beautiful and generous, and it is more convenient to bind. Moreover, Adhesive Tape  the tape has almost no weight, so you don't have to worry about weighing with straw rope.

However, the information that the tape used to bind vegetables is "poisonous" has spread wildly on the Internet in recent days. Some even claim that "the formaldehyde exceeds 10 times the standard, and long-term consumption of vegetables bound with tape may cause cancer".

Just search, there will be a lot of relevant information

For a time, people were terrified. In addition, it was approaching the time of hoarding vegetables during the Spring Festival. Many friends didn't know what to do.

So, can I buy the vegetables tied with tape? Today, the health headline (wechat: Baojia and Aifu) invited the doctor of food safety to tell you about the tape binding vegetables.

Tape = plastic film + adhesive

To find out whether the vegetables bound with tape are poisonous, we must first know what the tape is.

These tapes are similar to the transparent adhesive usually used. They mainly have two parts, one is the plastic film, and the other is the adhesive coated on the plastic film.

These plastic film tapes, due to direct contact with food, need to comply with the provisions of the food safety law and relevant food safety standards.

There are national standards for plastic film and adhesive respectively, so strictly speaking, Adhesive Tape  the tape produced according to national standards will not have much safety problem.

However, there is still no special product standard for the tape used to bind food, that is, there is no "food grade" tape.

Of course, even if there is "food grade" tape, it is likely that most vendors will still use ordinary tape for cost reasons.

Is it safe to bind vegetables with tape?

You can rest assured that it is safe to bind vegetables with tape.

Plastic film and adhesive are polymers, which are very stable under natural conditions, and there is little possibility of degrading and releasing a large amount of formaldehyde.

Even if there are some formaldehyde residues in the production process, there is only a narrow strip of tape for binding vegetables, and these residues can be ignored.

For example, Shenzhen Quality Inspection Institute tested 11 Adhesive Tape vegetable and tape samples bound with tape, and the results confirmed the conclusion of "tape safety":

In 11 samples, formaldehyde was not detected at the contact part between vegetables and tape.

Although trace formaldehyde is detected in the tape, the premise is to soak the tape in 60 ℃ acetic acid for 2 hours before testing. This obviously can't happen to the vegetables we usually buy.

Don't worry too much

Seeing here, I believe we all know that there is no health hazard in binding vegetables with tape.

Coupled with the strong water solubility and volatility of formaldehyde, it is difficult for them to Adhesive Tape  accumulate on the surface of vegetables. Even if a small number of "leakers" ran to the dishes, they ran away in the process of picking, washing and frying.

If you are really worried, you can also cut off the winding part of the tape. In particular, the tape has been stuck for a long time, and the vegetable surface has become sticky. At this time, it's better to throw away the part wrapped with the tape.

Although it is not recommended to wrap vegetables with tape, generally speaking, there is no health hazard. You don't have to be alarmed by a news.
