It is undeniable that disposable tableware brings a lot of convenience to our daily diet. School students and urban white-collar workers are the main consumers of disposable tableware. For them, disposable lunch boxes are more like an indispensable part of life. They generally believe that disposable lunch boxes are both economical and convenient, and even believe that cross-infection can be avoided and bacterial growth can be reduced. In fact, due to the widespread abuse of disposable lunch boxes, this is not the case. Let's take a look at some of the bad habits of improper use of disposable lunch boxes.
Use a foamed disposable lunch box to hold hot dishes and hot soup. Foamed tableware is made of PS (polystyrene) plus foaming agent. Due to the relatively low price, many unscrupulous manufacturers will add recycled materials to the raw materials, which will make the lunch box inferior. It is itself toxic. , can not directly contact the entrance food.
If it is a qualified foam disposable lunch box produced by a regular manufacturer, it is ok as a food tableware. However, the state has regulations that must be used below 70 °C. However, in reality, people often ignore this rule, and the foam lunch box is used directly for hot dishes and hot soup. The experimental analysis proves that the foamed disposable lunch box will deform when it is at a high temperature of about 90 °C, and release styrene monomer. The higher the temperature, the more the release, the long-term use will damage the liver and kidney function of the human body, and the development of the fetus.
The food packaged in the disposable lunch box is stored directly in the refrigerator. I believe this is the practice of most people after packaging, they believe that the disposable lunch box is only a few degrees in the refrigerator to keep fresh without any problems. In fact, it is not true. Everyone knows that food is not properly preserved in ordinary porcelain tableware. There is bacterial growth during overnight storage. It is not advisable to store food in a disposable lunch box for a long time. Therefore, when the food packaged in the lunch box returns home, you should change the tableware at home for the first time, try to reduce the contact time between the food and the disposable lunch box, and do not eat the soup contained in the disposable lunch box.
A disposable lunch box marked with a microwave can be placed in the microwave oven along with the lid. There are very microwave oven lunch boxes produced by the manufacturer. The box body is made of microwave PP (polypropylene) material, and the cover is a normal PS (polystyrene) material. Therefore, before the food is put into the microwave oven, the lunch box must be removed. Otherwise, the poison released by the lid at high temperature will also pollute the food.
Instant noodles with disposable lunch boxes, brewing cereals and other foods. This is actually the reason why the lunch box should not store overheated food. Even if the hot water for brewing food does not exceed the temperature of the lunch box, these foods should stay in the disposable lunch box for about half an hour, although not as fast as the high temperature release, but There will also be harmful substances released slowly.
