Use and deactivation of microwave oven

1. Don't heat the meat half-cooked. Because bacteria will still grow in half-cooked food, because the time is short, it is impossible to kill all bacteria when heating in the microwave oven for the second time. Frozen meat must be thawed in the microwave before it can be heated to maturity. 2. Avoid freezing the meat thawed in the microwave oven again: Because the meat has been thawed in the microwave oven, the outer layer has actually been heated at a low temperature, and bacteria can reproduce at this temperature. Although freezing can prevent bacteria from multiplying, it can't kill living bacteria. Meat that has been thawed in the microwave oven must be heated until it is completely cooked if it is frozen in the refrigerator again. 3, avoid fried food: because high-temperature oil will splash and cause fire. When there is an accidental fire in the furnace, don't open the door, turn off the power first, and then open the door to cool down after the fire is extinguished. 4. Avoid overtime heating: If 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. 5. Avoid using ordinary plastic containers: use special microwave utensils to hold food and put it in the microwave oven for heating. First, hot food will deform plastic containers. Second, ordinary plastics will release toxic substances, pollute food and endanger human health. 6. Avoid using metal utensils: When iron, aluminum, stainless steel, enamel and other utensils are put into the furnace, electric sparks will be generated when the microwave oven is heated, which will not only damage the furnace body but also heat unfamiliar food. 7. Avoid using closed containers: When heating liquid, use wide-mouth containers, because the heat generated by heating food in closed containers is not easy to dissipate, which makes the pressure in the containers too high and easily leads to blasting accidents. Even when cooking food with shells, you should pierce the shells with needles or chopsticks in advance to avoid bursting after heating, splashing to pollute the furnace wall or injuring people. 8. Avoid putting the oven in the bedroom: At the same time, be careful not to cover the cooling window grille on the microwave oven with objects. 9. Avoid working in front of the microwave oven for a long time: After turning on the microwave oven, people should stay away from the microwave oven or keep a distance of at least 1 meter from the microwave oven. Heating tips Different foods are heated in microwave ovens in different ways. Some foods, such as steamed bread, bread and steamed dumplings, will dry after repeated heating. When heating, it is best to cover them with special plastic wrap for microwave oven, or cover them to prevent water evaporation, which can also shorten heating time and save energy. But there must be air holes. You can poke a few small holes in the plastic wrap with a toothpick. Vegetables should not be covered or covered with plastic wrap when heated to prevent yellowing. When heating milk, it is best to pour it into a special container for microwave heating. Don't put it in the microwave oven with the whole package. When heating the platter, the thick parts of meat and vegetables should be placed on the edge of the platter, and the parts that are easy to heat should be placed in the center to avoid uneven heating. Food heated by microwave oven will lose moisture, so heat as much as you eat each time, and don't heat it repeatedly.
