What are the taboos of using microwave oven
1. Do not put ordinary plastic containers into microwave oven heating: first, hot food will deform the container; second, ordinary plastic will release toxic substances, contaminate food and endanger human health.
2. Avoid overtime heating: food is thawed or heated in the microwave oven. If you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.
3. Avoid the use of metal utensils: because the iron, aluminum, stainless steel, enamel and other metal utensils put into the oven, the microwave oven will generate electric sparks and reflect the microwave when heating, which will damage the furnace body and make cooked food.
4. Do not heat the meat until it is half cooked and then heat it in the microwave oven: because the bacteria in the semi cooked food are not completely killed, even if they are put into the refrigerator, the bacteria will still grow. When the meat is heated in the microwave oven for the second time, it is impossible to kill all the bacteria due to the short time. Frozen meat must be thawed in the microwave oven, and then heated for cooked food.
5. Do not use closed containers: when heating liquids, use wide mouth containers, because the heat generated by food heating in closed containers is not easy to emit, which makes the pressure in the container too high, which is easy to cause explosion accidents. Even when cooking food with shell, the shell membrane should be punctured with needle or chopsticks in advance, so as to avoid bursting and splashing after heating and dirty the furnace wall.
6. Avoid refreezing the meat thawed in the microwave oven: because after thawing in the microwave oven, the outer layer of meat is actually heated at a low temperature. At this temperature, bacteria can reproduce. Although re freezing can stop the reproduction, it can not kill the living bacteria. The meat that has been thawed in the microwave oven must be heated until it is fully cooked if it is frozen in the refrigerator again.
7. Avoid fried food: due to high temperature oil will splash, resulting in open fire. In case of fire in the furnace caused by carelessness, do not open the door, but turn off the power supply first, and then open the door to cool down after the fire is extinguished.
8. Avoid contacting food with preservative film: when using preservative film, it is better not to let it contact food directly during heating. Put food at the bottom of a large bowl, seal the bowl with preservative film, or cover the bowl directly with glass or porcelain without plastic film. In this way, water vapor can be sealed and heating can be quickly and evenly distributed. Before taking out the food, the plastic film can be punctured to prevent it from sticking to the food.
9. Avoid working in front of microwave oven for a long time. After the microwave oven is turned on, people should be away from the microwave oven or at least 1 meter away from the microwave oven.
10. Avoid placing the microwave oven in the bedroom, and pay attention to the radiator grille on the microwave oven not to be covered by articles.
