Is it harmful to eat microwave food?

Do not put ordinary plastic containers in the microwave oven to heat: first, hot food will deform the container, and second, ordinary plastic will release toxic substances, contaminate food, and endanger human health.

Do not use metal utensils: Because the iron, aluminum, stainless steel, enamel and other metal utensils put into the furnace will produce electric sparks and reflect microwaves with the microwave oven when heated, which will not only damage the furnace body but also make uncooked food.

Do not use closed containers: Wide-mouth containers should be used when heating liquids, because the heat generated by food heating in closed containers is not easy to dissipate, so that the pressure in the container is too high, which is easy to cause explosion accidents. Even when cooking food with shells, it is necessary to puncture the shell membrane with a needle or chopsticks in advance to avoid bursting, splashing and staining the walls of the oven after heating.

Do not make the plastic wrap contact with food: when using plastic wrap, it is best not to let it directly contact the food during the heating process, you can put the food into the bottom of the large bowl, seal the bowl mouth with plastic wrap or directly cover it with glass or porcelain without plastic wrap, so that the water vapor can also be sealed, so that the heating is rapid and uniform. Before removing food, puncture the plastic wrap to prevent it from sticking to the food.

Microwave oven heating food is not too harmful to the human body. The mechanism of microwave oven heating food is to use microwaves to cause violent friction and collision of water molecules in the food, and generate a large amount of heat to heat the food, which is a kind of physical effect.

Microwave oven to heat food is not too harmful to the human body. The mechanism of microwave oven heating food is to use microwaves to cause violent friction and collision of water molecules in food, and produce a large amount of heat to heat food, which is a kind of physical action.

When heating food, microwaves need to be used to make the molecules in the food beat quickly and play a role in heating. Many people believe that this principle leads to the destruction of the molecular structure, which in turn leads to the production of carcinogens. In fact, this statement is not credible, the energy carried by microwaves is far from the extent of destroying food molecules, and the food is still the original food after heating, and will not produce carcinogens.

The microwave oven needs to close the furnace door when working, and the furnace door can play a good shielding role during the working process, and the microwave that can leak out is very small, which is only equivalent to the radiation of a 10-watt sunshine lamp. Even if the microwave oven accidentally opens the door while working, the microwave oven will stop running and will not bring additional radiation to the human body.

At the same time, the metal shell of the microwave oven produced by the regular manufacturer has a very good shielding effect, and the amount of microwave radiation that the human body can receive is actually very small.

Precautions for the use of microwave ovens

1. Do not heat the meal in the microwave for more than 8 hours, because if the time is too long, the food will spoil and it will hurt the stomach, but the time should not be too short, otherwise the bacteria in the food have not been killed. It is recommended to pay attention to the cooking time when you are busy and make the food more nutritious.

2. When heating, cover the lid slightly to avoid a large loss of moisture in the food, but it also depends on the type of food, in addition, the food needs to be thawed before being heated in the microwave.

3. The microwave oven can heat the meal for about two minutes, do not use plastic. While the plastic itself is not heated, hot food can make the container very hot. These plastic containers can release toxins and contaminate food at high temperatures.

There is no harm. In the busy fast-paced life, many people are accustomed to using the microwave to heat food, it is convenient to cook food in the microwave, put cold or raw food in the microwave, close the door, press the switch, the food is turned in the microwave for a while, and it is heated and cooked.

Introduction:

Microwave ovens heat food through microwave radiation, but household appliances will have a certain amount of radiation, which is non-ionizing radiation, which is low-energy electromagnetic radiation, such as ultraviolet rays, light, infrared rays and microwaves, etc., their energy is not high, this radiation does not cause harm to the body, so there is no need to worry too much.

The microwave oven does not rely on fire to heat food, but by microwaves, that is, high-frequency electromagnetic waves, as the heat source of microwave ovens, microwaves are electromagnetic waves with a frequency of 300 megahertz to 300,000 megahertz, and the microwave oven is actually a microwave generator, and the microwave frequency it produces is 2450 megahertz, which has a very interesting habit.

When encountering water-rich foods such as meat, poultry eggs, and vegetables, the microwave will stay, and drag the water molecules in the food to oscillate with it at the same frequency, causing molecules to rub against each other, friction can produce heat, the higher the oscillation frequency, the greater the amplitude, the more intense the friction between molecules, and the more heat generated.
