The advantages of microwave heating are high heating speed and little damage to nutrients in food. The main principle is that water in food can generate molecular oscillation and release energy, thus playing a heating role, and no new substances will be produced in the process.
In addition, the radiation generated by microwave heating is non-ionizing radiation, which is usually harmless to human body, so using microwave oven will not cause cancer.
However, if the microwave oven is improperly used, such as burning food and burning it, it may produce harmful substances such as acrylamide, and long-term excessive intake may have a certain carcinogenic effect.
Use taboos:
1, avoid using ordinary plastic containers.
One is that hot food will deform plastic containers, and the other is that ordinary plastics will release toxic substances, pollute food and endanger human health.
2. Avoid using metal appliances.
As 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 the food.
3. Avoid using closed containers.
Wide-mouth containers should be used when heating liquid, because the heat generated by heating food in a closed container is not easy to dissipate, which makes the pressure in the container too high and easily leads to blasting accidents.
4. Avoid bottled food with narrow bottlenecks.
Even if the lid is opened, it will expand due to pressure and cause an explosion.
5. Don't put the half-full bottle of baby food or the original bottle into the furnace for heating, so as not to break the bottle.
