10 facts and myths about the microwave

1. Myth: the explosion of an iron plate

There are persistent allegations that an iron plate can not be damaged by the magnetron due to arcing. Microwave radiation can not penetrate into metal objects. Metal utensils and metal appliances (spoons, forks) that are in the oven during heating can disable it.

2. Myth: about the German, military origin of the microwave oven

For the first time, the microwave oven, called Radiomissor, was allegedly developed by German scientists during World War II, it even allegedly was used in the active German army to warm up food, but proved unsafe, and was abandoned. Kin and Rajasthan).

3. Myth: microwave causes loss of nutrients

In fact, any process of cooking leads to the loss of nutrients and vitamins. The microwave is the heats the food, as a result of which there is a loss (the decay of evaporation, etc.) of a part of the substances.

4. Myth: about allergies

The myth of an allergy sounds like this: A microwave oven can cause allergies … to electromagnetic waves.

10 facts and myths about the microwave

1. Myth: the explosion of an iron plate

There are persistent allegations that an iron plate can provoke an explosion of high power (in fact, in the worst case, it will cause damage to the magnetron due to arcing). Microwave radiation can not penetrate into metal objects. Metal utensils and metal appliances (spoons, forks) that are in the oven during heating can disable it.

2. Myth: about the German, military origin of the microwave oven

For the first time, the microwave oven, called Radiomissor, was allegedly developed by German scientists during World War II, it even allegedly was used in the active German army to warm up food, but proven unsafe, and was abandoned (Russian sites referenced on it on foreign, and foreign – on the Russian researches supposedly spent in nonexistent Russian cities Kinsk and Rajasthan).

3. Myth: microwave causes loss of nutrients

In fact, any process of cooking leads to the loss of nutrients and vitamins. The microwave is the heats of the food, as a result of which there is a loss (the decay of evaporation, etc.) of a part of the substances.

4. Myth: about allergies

The myth of an allergy sounds like this: A microwave oven can cause allergies … to electromagnetic waves.

5. Myth: microwaves are radioactive

Microwave ovens are not radioactive. They, just like the sun and fire, just heat food. The furnaces emit microwaves, which cause the friction of water molecules (dipole shift), resulting in heating.

6. Myth: the heating of food in the microwave comes from within

There is a widespread opinion that the microwave oven heats food "from the inside out." In fact, microwaves go from the outside to the inside, stay in the outer layers of the food, so the heating of the evenly moist product occurs approximately the same as in the oven (to be sure, it is enough to heat the boiled potatoes "in a uniform", where the thin skin protects the product from drying.

The misconception is caused by the fact that microwaves do not act on dry non-conductive materials, which are usually on the surface of products, and therefore their heating in some cases begins deeper than with other heating methods (bread products, for example, are warmed up "from within", and it is for this reason – bread and rolls from the outside have a dried up crust, and most of the moisture is distributed inside.

7. Fact: in the microwave it is impossible to heat eggs

You can not heat a microwave in a microwave oven in hermetically sealed containers and whole bird eggs because of the strong evaporation of water. From the same considerations, it is undesirable to strongly heat up.

8. Fact: Water in the microwave can be overheated

When heating water in a microwave, care should be taken – water is capable of overheating, that is, to heating. The superheated liquid can almost instantly boil away from careless movement. This applies not only to distilled water, but also to any water containing little suspended particles. The more smooth and homogeneous is the inner surface of the vessel. If the vessel has a narrow neck, then the probability is high that at the beginning of the boiling, the overheated water will pour out and will burn the hands.

9. Fact: The invention of a microwave oven occurred accidentally

American engineer Percy Spencer first noticed the ability of microwave radiation to heat foods and patented a microwave oven. At the time of the invention, Spencer worked at Raytheon, a company that manufactures radar equipment. According to legend, when he was experimenting with Another magnetron, Spencer noticed that a piece of chocolate in his pocket melted. The fantasy of fiction from the microwave, although the wrapper was made of foil more than bodies and chocolates, and noticeably change the temperature before the defeat of the organism. According to another version, he noticed that a sandwich was put on the included magnetron. Perhaps the cause of the invention was just a burn, but for commercial reasons, the image of the device was not worth the spoiling.

10. Fact: The USSR produced microwaves

In the USSR, from the mid-1980s, microwave ovens were produced at ZiL plants (the ZIL model) and YuzhMASh (the Mriya MV, Dnepranka-1 models (1990, 32 liters, capacity 2300 watts, weight 40 kg, price 350 rubles ), "Dnipryanka-2"), but they used imported Japanese-made magnetrons.
