We cannot live without a bowl every day, but do you really know the bowl you use? Some bowls cannot be used at will, long-term use will cause great harm to the body!
Tableware made of imitation porcelain looks a lot like ceramics. In fact, it is a plastic product. Generally, if there are children or elderly people at home, bowls made of this material are used as tableware, which are not easily broken and durable. Qualified melamine tableware is made of melamine and formaldehyde resin and can be used for food packaging. Inferior imitation porcelain tableware is made of urea-formaldehyde resin. Compared with qualified melamine tableware, inferior melamine tableware will decompose more harmful substances, such as formaldehyde, when heated.
After purchasing the imitation porcelain tableware, boil it in boiling water for 2-3 minutes in vinegar, or soak it in vinegar for 2 hours at room temperature. Do not use it for a long time to contain acidic, oily or alkaline foods to prevent harmful substances from being released from the porcelain bowl. After cleaning, it is best to wipe with a soft cloth, and do not rub the surface of the tableware with steel balls or sharp objects. If the tableware changes color, becomes white or cracks, do not use it again. It will cause more harm to the human body. Porcelain tableware usually must be replaced within 3-5 years.
How to distinguish true and false imitation porcelain tableware?
Look at the label
Qualified melamine tableware will have the QS mark (food quality and safety mark) on the bottom of the bowl to indicate the specifications for use.
The price of urea-formaldehyde resin is cheaper than that of formaldehyde resin. The price of ordinary imitation porcelain tableware is more than 10 yuan, and the price of inferior products is generally relatively low.
If the color of the melamine tableware is very bright and attractive, it is likely to be inferior, please do not buy it.
