Because heat and oil will promote the dissolution of harmful ingredients and pollute the food.
- Use the special plastic appliances for microwave ovens produced by regular manufacturers.
The special plastic containers for microwave ovens shall be translucent, colorless, and heat-resistant products. When a microwave oven is used to heat food with high water content, PP plastic container can be used; When heating dishes and foods with more oil, PC containers with stronger temperature resistance should be selected; If heating nonliquid food, do not use any plastic containers.
Use the microwave oven to heat food. It is better to use glass containers or porcelain without any dye inside.
- Avoid using non-heat-resistant containers to hold hot food.
Some plastic bottle containers will become soft and deformed in case of heat. Do not try to use such containers to contain overheated food. Although this kind of plastic is safe at room temperature, it may decompose and release harmful components at high temperatures. It is common for people to put hot boiled water and hot tea into mineral water bottles or drink bottles. This practice has certain health hazards.
