Although the report also pointed out that the plasticizer content of the seven samples was lower than that specified in the European standard, the white-collar workers with rice were still worried.
The experts of the Food Packaging Association said that the polypropylene material used in most microwave oven plastic lunch boxes has good heat resistance and can be sterilized at above 100 ℃ without deformation at 150 ℃ without external force. Generally, heating in a microwave oven for a short time will not precipitate excessive plasticizer. However, if the temperature exceeds the heat resistance, the plasticizer may also be released. It is necessary to avoid heating the plastic lunch box with high temperature for a long time.
1. Pay attention to the production date. The shelf life of plastic products is generally three to five years. If it is used frequently, it is better to replace it in one to two years.
2. When purchasing, pay attention to whether there is QS mark and number, whether there is material description and precautions for use, and whether there is the word "microwave use". Choose a transparent lunch box.
3. The lid of some disposable lunch boxes may not be made of heat-resistant materials, so the lid should be removed when heating.
4. Avoid using plastic boxes to heat foods with a large amount of fat and high sugar content, because the boiling point of oil is easier to exceed the heat resistance of plastic, and oil, sugar and plasticizer are organic substances, which are similar to each other.
Lunch, for most white-collar workers, is nothing more than ordering takeout, eating boxed lunch, bringing a bento, and going to a restaurant for lunch. It is unavoidable to deal with disposable lunch boxes in these ways. Microwave oven lunch boxes and disposable lunch boxes have encountered quality problems, which many white-collar workers fear. In fact, facing the relative disposable lunch box every day, we should learn to choose and use the disposable lunch box correctly.
