It is undeniable that disposable tableware brings a lot of convenience to our daily diet, and people generally believe that disposable lunch boxes are economical and convenient. They even think that they can avoid cross-infection and reduce the growth of bacteria. In fact, because people generally use disposable lunch boxes The bad habit of lunch boxes is not the actual situation. Let's take a look at the bad habits of inappropriate use of disposable lunch boxes?
Use foam disposable lunch boxes to hold hot dishes and hot soups. Foam tableware is made of PS (polystyrene) plus a foaming agent. Due to the relatively low price, many unscrupulous manufacturers will add recycled materials to the raw materials, which results in the lunch boxes being inferior and toxic in themselves. , cannot come into direct contact with food.
If it is a qualified foam disposable lunch box produced by a regular disposable lunch box manufacturer, it can be used as food tableware. However, the state stipulates that it must be used below 70°C. But in reality, people often ignore this requirement, and foam lunch boxes are directly used to hold hot dishes and hot soup. Experimental analysis has shown that foamed disposable lunch boxes will deform when exposed to high temperatures of around 90°C and release styrene monomer. The higher the temperature, the more styrene monomer will be released. Long-term use will damage the liver and kidney functions of the human body and the development of the fetus.
Food packed in disposable lunch boxes is stored directly in the refrigerator. I believe this is what most people do after packing. They think that there is no problem in keeping disposable lunch boxes fresh in the refrigerator at only a few degrees. In fact, this is not the case. As we all know, if food is stored improperly in ordinary porcelain tableware, bacteria will breed if it is stored overnight. It is even more undesirable to store food in disposable lunch boxes for a long time. Therefore, after returning home, the food packed in the lunch box should be replaced with the tableware at home in time to minimize the contact time between the food and the disposable lunch box, and do not eat the soup contained in the disposable lunch box.
Disposable lunch boxes marked as microwave-safe should be placed in the microwave together with the lid. There are microwaveable lunch boxes produced by many manufacturers. The box body is made of microwaveable PP (polypropylene) material, and the lid is made of ordinary PS (polystyrene) material. Therefore, be sure to remove the lunch box before putting the food in the microwave to heat it, otherwise, the poisons released by the lid at high temperatures will also contaminate the food.
Use disposable lunch boxes to make instant noodles, cereals and other foods. This is actually the reason why lunch boxes should not store overheated food. Even if the hot water for brewing food does not exceed the tolerable temperature of the lunch box, these foods will stay in the disposable lunch box for about half an hour. Although the high temperature is not released as quickly, it will Harmful substances will also be slowly released.
You should still use disposable tableware as little as possible in your life. If you have to use disposable lunch boxes, you should carefully choose qualified lunch boxes, stay away from the above bad habits, and use disposable tableware rationally.
