How to judge whether the plastic box is a special box for the microwave oven
The plastic box has 1-7 security levels, which are marked in the triangular arrow box at the bottom of the plastic box. The heat resistance and function of each safety grade plastic are also different. The number in the triangle arrow box is 5, which can be used as a microwave lunch box.
Will plasticizers be produced when the plastic box is placed in a microwave oven? Another teacher in the Department of Food Science at the College of Environmental Science and Engineering at Anshida said that it depends on whether the plasticizer is added to the lunch box during the manufacturing process. When added, it is likely that the plasticizer will evaporate due to heating in the microwave oven. The plastic box is heated at a high temperature in a microwave oven, which releases harmful substances in the production material, not only in the microwave oven, but also in the plastic cup. Although there is no evidence that microwave heating is not good for the human body, plastic products are used as little as possible for heating.
