What can't be heated by microwave oven!
Sihaiwang: microwave oven is the most common electrical appliance in our kitchen. It's convenient and fast to use it to heat things, but there are many things and things that can't be put into microwave oven for heating. Let's take a look at the taboo of using microwave oven!
The ten taboos of microwave oven
1. Do not heat the meat until it is half cooked and then use microwave oven to heat it: because bacteria will still grow in the half cooked food, it is impossible to kill all the bacteria due to the short time when using microwave oven for the second time. Frozen meat must be thawed in microwave first, then heated to cooked food.
2. Avoid refreezing the meat thawed in microwave oven: because the meat has been thawed in microwave oven, in fact, a layer of low temperature has been heated outside. Under this temperature, bacteria can reproduce. Although refreezing can stop their reproduction, it cannot kill the living bacteria. If the meat that has been thawed in microwave oven is put into refrigerator for freezing again, it must be heated to full ripe.
3. Avoid fried food: high temperature oil will splash and cause fire. In case of fire in the furnace due to carelessness, do not open the door, but turn off the power first, and then open the door to cool down after the fire goes out.
4. Avoid overtime heating: put the food into the microwave oven for thawing or heating. If you forget to take it out, if the time is more than 2 hours, you should discard it to avoid food poisoning.
5. Do not use ordinary plastic containers: use special microwave oven containers to hold food and put it into microwave oven for heating. First, hot food will deform the plastic containers. Second, ordinary plastic will release toxic substances, pollute food and endanger human health.
6. All the metal tableware, bamboo ware, plastic ware, lacquer ware and other heat-resistant containers, with concave and convex glass products, should not be used in the microwave oven. The iron, aluminum, stainless steel, enamel and other utensils put in the oven will generate electric sparks and reflect the microwave when the microwave oven is heated, which will not only damage the oven body but also heat the uncooked food. The porcelain dishes cannot be inlaid with gold or silver lace. The container for food must be placed in a special plate for the microwave oven, not directly in the oven cavity.
7. Do not use closed containers: wide mouth containers should be used when heating liquid, because the heat generated by food heating in the closed containers is not easy to dissipate, so that the pressure in the containers is too high, which is easy to cause explosion accidents. Even when cooking food with shell, you should prick the shell with needle or chopsticks in advance to avoid bursting, splashing and dirtying the furnace wall, or splashing and hurting people after heating.
8. Avoid placing the micro oven in the bedroom: at the same time, pay attention not to cover the cooling window grid on the microwave oven with articles.
9. Avoid working in front of the microwave oven for a long time: after opening the micro oven, people should be away from the microwave oven or at least 1 meter away from the microwave oven.
10. Eggs with shell and food with sealed package cannot be cooked directly to avoid explosion
