Mistakes in using microwave oven
First, heating time misunderstanding
People often put food in the microwave oven to thaw or heat, sometimes forget to take out, put for a few hours. If you forget to take it out for more than 3 hours, it's better to throw it away, so as not to cause food poisoning. Moreover, the food heated for a long time is easy to dry due to the rapid loss of water diversion. In addition to poor taste, the nutritional value of food will be greatly reduced.
Second, the misunderstanding of cooking containers
Maybe you're used to putting packaged food and plastic lunch boxes in the microwave oven, which is absolutely not allowed. Because plastic containers can deform during heating and release toxic substances to contaminate food, which can cause cancer in the long run. In addition, it should be noted that metal containers are also not desirable, because sparks will be generated during microwave heating, which will not only damage the furnace body, but also cause explosion. We should use the special container of microwave oven to heat food, and do not cover the container tightly during the heating process, because the heat generated by heating food in the closed container is not easy to emit, which makes the pressure in the container too high and easy to cause explosion accidents.
Third, the heating of food taboo
It is better not to fry food in microwave oven, because high temperature will make oil splash and cause fire. If there is a fire in the oven, do not open the door of microwave oven, cut off the power supply first, and then open the door after the fire is extinguished. In addition, when cooking food with shell, the shell should be punctured first to avoid explosion.
Fourth, mistakes in freezing or heating
Although it can shorten the cooking time, the bacteria will still grow when the food is half cooked. When the meat is reheated in the microwave again, it is impossible to kill all the bacteria if the time is too short. In this case, frozen meat can be thawed in the microwave oven, and then heated for cooked food, so that you can rest assured of eating.
Fifth, is it necessary to cover food when cooking in the microwave oven?
Yes. When cooking with a stove, we usually cover the pot when stewing food. That's to get a unique burnt flavor, but the microwave oven can't. What we don't understand is that during the stewing process, a large amount of vitamin in the food is lost, which causes this flavor. If you want to maximize the nutrition of meat, you'd better cook it on the stove for a while, and then heat it in the microwave oven until it matures.
Sixth, the wrong position
As the microwave oven has radiation, so do not put it in the bedroom, should try to put it in a ventilated place. And also with television, radio away from a certain distance, otherwise it will affect the audio-visual effect. After opening the micro furnace, it is better to keep a distance of 1 meter from it, and do not look directly at it. Otherwise it will cause dizziness, dizziness, fatigue, weight loss, hair loss and other symptoms.
Seventh, microwave processing of food can kill bacteria?
correct. Microwave heated food, bacteria and viruses can be eliminated. But we need to differentiate between raw and cooked food. Cooked food should be microwave heated for at least 10 minutes before serving, so that the bacteria in the food can be completely killed. Raw and frozen ingredients need to be heated longer.
Eighth, don't put food in the microwave oven?
Error. We must treat frozen food and fresh food differently. It won't be a big problem to heat these foods in the microwave oven, but pay attention to the heating method. For the ingredients we store in the refrigerator or freezer, the treatment is the same as leftovers. Some people may think that frozen and reheated ingredients will become tasteless, but in fact, there is no change in the nutrients.
