2. Avoid heating ordinary plastic containers and plastic bags in the microwave oven. Ordinary plastic containers and plastic bags are not resistant to high temperature and are easily deformed when heated. In addition, it may release toxic substances at high temperature, which is harmful to health. You should try to choose a special container for microwave ovens with high temperature resistance.
3. Avoid heating fried food. High temperature will spill oil, which may lead to open fire and fire. Do not open the door immediately if there is a fire in the furnace by accident. Turn off the power first, and then open the door when the fire goes out.
4. Avoid using metal appliances. The working principle of microwave oven is to use electromagnetic waves to heat food. Electromagnetic waves will react with metals, and there is no way to absorb and conduct them, so it is impossible to heat food in metal utensils.
Microwave ovens are generally used to heat meals, sausages and food. Everything used in the microwave oven should be heated in the microwave oven container, so as to ensure that the heated food tastes good, but there are nine taboos to pay attention to when using the microwave oven.
5. Raw meat thawed in microwave oven should not be frozen in refrigerator. Because after the meat is thawed in the microwave oven, it has actually heated the outer layer at a low temperature, and bacteria can reproduce at this temperature. Even if freezing can prevent bacteria from multiplying, it can't kill live bacteria. If the meat thawed in the microwave oven is frozen in the refrigerator again, it must be heated until it is fully cooked.
6. Avoid using closed containers. After the microwave oven is heated, the local high temperature produces steam, that is, high pressure is produced. Once a closed container is used, an explosion may occur. If you use a container with air holes, even if it is food with a shell, you should first pierce the shell with chopsticks.
7. Avoid heating food wrapped in plastic wrap. Under the condition of high temperature, plastic wrap will change chemically, which will bring hidden dangers to food safety.
8. Don't put anything in the microwave oven. There is an air outlet above the microwave oven. If it is covered by other objects, it will lead to the aging of the microwave oven due to excessive temperature, and may also cause a short circuit.
9. Avoid standing around the microwave oven when it is working. In order to reduce microwave radiation, it is best to keep a distance of at least 1 m after the microwave oven is turned on, and don't stare.
