Description of the Microwave Oven

The advantages of a microwave oven:

In a conventional oven the heat radiated by the
resistances or gas burners, slowly penetrates the
food from the outside to the inside. There is,
therefore, a great loss of energy in the heating of
the air, oven components and recipients.
On the other hand, in microwave ovens the heat is
generated in the interior of the food itself, heating
it from the inside outwards. There is therefore no
loss of energy as the air, interior walls of the oven
and recipients (when adequate) do not heat up
with microwaves.
In short, microwave ovens have the following
advantages:
1. Save on cooking time: in general there is a
3/4 reduction of the cooking time than with
conventional methods.
2. Ultra-quick defrosting that prevents bacteria
development.
3. Electricity saving.
4. Maintaining the nutritive value of the food due
to the cooking time reduction.
5. Easy cleaning.

How the microwave oven works

In the microwave oven there is a high voltage
valve called "Magnetron" that converts electric
energy to microwave
electromagnetic waves are conducted to the
inside of the oven cavity by means of wave-guide
and spread by a mode stirrer or by a turntable.
Inside the oven the microwaves spread out in all
directions and are reflected by the metallic walls,
penetrating the food evenly.

Why does the food heat up?

Most food contains water, whose molecules
vibrate with microwaves.
The friction between the molecules generates
heat, which causes a temperature rise in the food,
defrosting it, cooking it or keeping it warm.
As the heat is formed inside the food:
- It may be cooked with little or no liquid or fat;
- Defrosting, heating or cooking in the microwave
oven is quicker than in a conventional oven;
- Vitamins, minerals and nutritive substances are
preserved;
- There is no change in the natural colour and
smell of the food.
The microwaves pass through porcelain, glass,
cardboard or plastic but not through metal.
Therefore, recipients made of or containing metal
should not be used in the microwave oven.
The microwaves are reflected by the metal...
...they pass through glass, porcelain...
...they are absorbed by the food.
