Long-term use of microwave oven to heat food will cause cancer?

The idea that long-term use of microwave heating food can cause cancer is, indeed, a rumor! The principle of microwave heating The principle of microwave heating is to make polar molecules (such as water and protein) rotate rapidly through the change of electric field direction, thus generating heat through the friction of molecular motion. Many natural ingredients are high-moisture foods, such as fish, meat, eggs and milk, fruits and vegetables, and porridge and soup, so they are more suitable for microwave heating There is no evidence that microwave heating can directly produce carcinogens, and even, if the microwave oven is used correctly, it can help avoid the production of carcinogens. Compare with traditional cooking methods Traditional cooking methods, such as frying fish and meat, grilling meat (especially when charred), the temperature can easily be too high (more than 200 ℃), thus producing carcinogens. In contrast, if you microwave leftovers and high-moisture food, the temperature of the food will not exceed 100 ℃ as long as the water is not dried out. Does microwave heating lose nutrition? Any cooking method will have a certain amount of nutrition loss. As long as the heating time and temperature are reasonable, microwave heating is no more nutritional loss than gas heating. There are many studies that prove that when vegetables and fruits are cooked in microwave ovens, the loss of vitamin C, flavonoids and chlorophyll is smaller because of the fast heating speed and short heating time. What kind of dishes are suitable for microwave oven? High-moisture foods, such as porridge, rice, noodles, milk and vegetables, are more suitable for heating in the microwave oven. Because microwave heating of food may be unevenly heated, for food safety, it is recommended to take the food out halfway and stir or turn it several times to evenly heat it. Microwave cooking eggs turned into a bomb? It’s true. Microwaving eggs turns them into bombs. Food with shells that have membranes (such as egg yolks) or shells are not suitable for microwave heating and can easily explode. Even without the shell, the yolk of an egg has a membrane. The moisture content of the yolk is low, and when microwaved, the temperature soars and a lot of steam is generated. However, the steam is wrapped in the yolk membrane and cannot be dispersed, so the yolk membrane is eventually broken and the yolk bursts everywhere. Microwave fried eggs tip: Beat the eggs on a flat plate and poke a few holes in the yolk with a toothpick, then microwave for about 40 seconds. Microwave boiling water with coffee powder will spurt? It’s true. Microwave boiled water with coffee powder will erupt. When water is microwaved, the water does not flow, but the temperature rises, and it may exceed the boiling point without the sign of “boiling”. At this time, as long as there is a little disturbance (such as you open the microwave door to get the water), it will boil fiercely, it is easy to burn. What foods are not suitable for microwave heating? High-fat food with little moisture such as cheese, nuts, pancetta, because of the low moisture, microwave heating, the temperature rises particularly quickly, it is easy to scorch or fried. In addition, dried fish, dried meat and other moisture content is too low, microwave heating is very easy to scorch and produce carcinogens. So these foods with microwave heating should be very careful, strict control of time, it is best to switch to other heating methods. Which containers can not be placed in the microwave oven heating? 1, any material containing metal, including porcelain cups or porcelain plates with gold patterns. Otherwise you will see the flash of fire in the microwave oven, and then these beautiful patterns are all ruined. 2, the paper box may overheat, or even catch fire. 3, the ordinary food plastic bags bought outside you have no idea of the temperature resistance of these materials. The bottom labeled “microwaveable” except for lunch box products.
