1, because microwave is a kind of radiation, there is a wrong view that it will cause cancer. In fact, microwave is an electromagnetic wave, which is essentially the same as radio waves, infrared rays and visible light used in radios and telegrams. The only difference between them is the frequency. The frequency of microwave is higher than electric wave, and lower than infrared ray and visible light. Electromagnetic waves in this frequency band are not carcinogenic.
2. Scientific research has found the minimum microwave power that is harmful to human body, and based on this, the standard of microwave oven leakage power has been established. For example, the United States stipulates that the power per square centimeter should not exceed 5 milliwatts at a distance of about 5 centimeters from the microwave oven; China's standard is more stringent, which is 1 milliwatt. Moreover, the energy of microwave decreases according to the square of distance. Calculated by 5 cm 1 milliwatt, it is reduced to 1 milliwatt at 50 cm. Therefore, as long as it is a qualified microwave oven product that is not damaged in use, it will not leak microwaves that can harm the human body.
3. If the microwave oven is used for heating, it generally does not need to reach 100 degree or above; For porridge, soup, milk, rice, noodles and other high-moisture foods, as long as the water is not evaporated, the food temperature will always be maintained at 100 degrees, and there will be no carcinogens. Therefore, the normal use of microwave ovens will not cause carcinogens in food. Even according to relevant research, compared with traditional heating methods, especially burning, roasting and frying, microwave ovens can effectively reduce the generation of the above carcinogens.
4. Some plastics may release some harmful ingredients when heated. The US Food and Drug Administration (FDA) has determined the amount of harmful substances that various plastic containers may release into food during normal microwave heating, and it is required that this amount is less than 1% or even 1% of the harmful dose determined by animal experiments before it can be marked as "microwave-heatable". Therefore, it is quite safe for those qualified plastic containers marked as "microwave heatable". If you are not at ease, you can also use ceramic or glass containers.
