Unqualified melamine tableware is easy to release formaldehyde.
30 Dec 2018

Unqualified melamine tableware is easy to release formaldehyde.



Good-looking and drop-resistant melamine tableware, used by many families. Recently, some media reported that unqualified imitation porcelain bowls will release formaldehyde at high temperatures, which is very harmful to people. Yesterday, the reporter of Modern Express visited the tableware market and found that most of the melamine tableware on the wholesale market did not have the QS certification mark, and the quality was difficult to guarantee. Professionals caution that even qualified enamel bowls should be used with caution.




Most of the melamine tableware on the wholesale market does not have the QS mark. Modern Express reporter Xu Yang.

Many imitation porcelain bowls have no QS logo


Yesterday, the reporter came to a tableware wholesale market near Xinjiekou, Nanjing. Speaking of the imitation porcelain bowl, the merchants took out some and said that this is called "melamine bowl." The bowls are slightly rough and have no labels. The owner of the wholesale store said, "The quality is definitely no problem. The nearby small restaurants are all taken from here."


Later, the reporter went to a large supermarket, where the "melamine" bowls were more varied and expensive. But look carefully, the surface of the imitation porcelain bowl in the supermarket is much smoother and thicker to the touch. At the same time, each bowl has a label with the QS mark on it and an implementation standard QB1999-1994. The reporter learned that this standard is the national standard for melamine plastic tableware. In addition, each tableware is marked with the words "Do not heat in the microwave oven".

"Three nos" bowl boiled boiled with odor


Since there is a national standard, why is it that the imitation porcelain bowl is harmful and easily emits harmful gases such as formaldehyde? Lu Xianming, consultant of the Nanjing Food and Beverage Disinfection Industry Association, said that many manufacturers are making fakes at the source of production. It is difficult to ensure that the material of melamine tableware is 100% pure melamine. The Jiangsu Provincial Quality Supervision Bureau has also conducted sampling inspections on market melamine tableware, and the sample pass rate is 75%.


How to confirm that the melamine bowl is unqualified, can it be used? Experts said that the tableware was boiled in boiling water for 30 minutes, and there was whitishness, bubbles, cracking, or a pungent smell.


In order to verify this statement, the reporter purchased a melamine imitation porcelain bowl from the wholesale market and supermarket, and put it into boiling water to cook. After 30 minutes, the melamine bowls purchased from the supermarket did not change much; the "three no" melamine bowls purchased from the wholesale market clearly smelled of pungent plastic.


The qualified imitation porcelain bowl will be changed in half a year.


So qualified melamine imitation porcelain bowls can be used with confidence? Not at all! Sun Dunbing, secretary general of the Nanjing Food and Beverage Disinfection Industry Association, said that even if it is a qualified bowl, it will not be heated and not placed in a microwave oven. It will be replaced after half a year and up to one year. " Melamine tableware will not toxic gas in a short period of time, but will release toxic gases slowly after half a year and need to be replaced in time."

In order to make the melamine bowl look better, especially for the melamine bowl for children, there will be a lot of bright colors, and it is more likely that the heavy metal will exceed the standard. Experts suggest that you try to use ceramic bowls. If you want to buy imitation porcelain bowls, be sure to check whether the products have QS logo and production license, and try to use white and unpatterned bowls.
