Why can't the microwave oven heat sealed food? -Alice

November 20, 2021

The microwave oven has become an indispensable "weapon" in every kitchen by virtue of its fast and convenient advantages, but everything has both good and bad sides. While the microwave oven is convenient, it is not absolutely safe to use. Pay special attention to the following 9 Taboos.

1. Avoid too long heating time. The microwave oven uses high-frequency heating, and the heating speed is very fast. Too long will make the food dry, harden, and even produce toxins. Therefore, when using, the time should be adjusted according to the type of food.

2. Avoid placing ordinary plastic containers, plastic bags, etc. in a microwave oven for heating. Ordinary plastic containers and plastic bags are not resistant to high temperatures and are easily deformed when heated. In addition, it may release toxic substances under high temperature, which is harmful to health. Should try to choose a high-temperature-resistant microwave oven special container.

3. Avoid heating fried foods. High temperature will cause oil to splash, which may cause open flames and fire. If you accidentally cause a fire in the furnace, do not open the door immediately, turn off the power first, and wait for the fire to go out before opening the door.

4. Avoid using metal utensils. The working principle of a microwave oven is to use electromagnetic waves to emit energy to heat food, and electromagnetic waves and metal will react, there is no way to absorb or conduct it, and it is impossible to heat the food in metal utensils.

5. Do not put the raw meat thawed in the microwave oven into the refrigerator again. After the meat is thawed in the microwave oven, the outer layer is actually heated at a low temperature, and bacteria can multiply at this temperature. Even if re-freezing can stop the growth of bacteria, it cannot kill the living bacteria. Meat that has been thawed in a microwave oven must be heated until it is fully cooked if it is placed in the refrigerator again.

6. Avoid using closed containers. The local high temperature generated by the microwave oven will generate steam, that is, high pressure. Once a closed container is used, it may explode. Use a container with air holes. Even if it is food with a shell, first use chopsticks to pierce the shell.

7. Avoid heating food wrapped in plastic wrap. Under high temperature conditions, the plastic wrap will undergo chemical changes, which will bring hidden dangers to food safety.

8. Avoid putting things in the microwave oven. The upper part of the microwave oven is equipped with an air outlet. If it is covered by other objects, the inside of the microwave oven will age due to high temperature, and a short circuit may occur.

9. When the microwave oven is working, avoid standing around it. In order to reduce microwave radiation, after the microwave oven is turned on, it is best to keep a distance of at least 1 meter, let alone stare at it.
