Precautions for Using Microwave Oven
July 28,2022
Sometimes, the improper use of microwave ovens will cause injuries to users, and a lot of things should be paid attention to when using them:
- Avoid overtime heating
Pay attention to the time of heating food in the microwave oven. Put the food into the microwave oven for thawing or heating. If you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.
- Avoid heating ordinary plastic containers
Never put plastic in the microwave oven. First, hot food will deform the container. Second, ordinary plastic will release toxic substances, pollute food and endanger human health.
- Do not heat the meat until it is half cooked and then heat it in a microwave oven
A microwave oven is the function of heating, and it can't cook food. Because bacteria will still grow in semi-cooked food, it is impossible to kill all bacteria due to the short time when they are heated in the microwave oven for the second time. Frozen meat food must be thawed in the microwave oven first, and then heated to cooked food.
- Avoid using metal utensils
Microwaves cannot penetrate metals. Because the iron, aluminum, stainless steel, enamel, and other metal utensils put into the microwave oven will generate electric sparks and reflect microwaves with it when heated, which will not only damage the oven body, but also make unsophisticated food, and it is also easy to cause a fire in serious cases.
- Avoid refreezing meat thawed in a microwave oven
Don't thaw food in the microwave. Because after the meat is thawed in the microwave oven, the outer layer has been heated at a low temperature. At this temperature, bacteria can reproduce. Although refreezing can stop their reproduction, it cannot kill live bacteria. Meat that has been thawed in the microwave oven must be heated until fully cooked if it is frozen in the refrigerator.
- Pay attention to safety when placing microwave ovens.
The microwave oven should be placed in a ventilated place, and there should be no magnetic substances nearby, so as not to interfere with the uniform state of the magnetic field in the oven cavity and reduce the work efficiency. We should also leave a certain distance from the TV and radio, otherwise, it will affect the visual and listening effects.
- The microwave oven cannot be empty.
Do not work with electricity when there is no cooking food on the stove. Do not make the microwave oven run without load, otherwise, the magnetron will be damaged. To prevent inadvertent no-load operation, a glass containing water can be built in the oven cavity.
- Microwave heating will expand the air in the sealed product.
Eggs with shells and food with sealed packages cannot be cooked directly to avoid explosion.
Microwave ovens not only bring convenience to us but also bring certain potential safety hazards. However, any electrical appliance will be in danger when used, so there is no need to be too taboo. As long as you pay attention to safety, you can use it properly.
