oven inner walls or utensils
(if they are microwave
compatible). In other words,
only the food is heated.
• Microwave ovens considerably
reduce cooking times. Time
needed in microwave cooking
is almost half or a third less than
the conventional ovens. A lot
depends on the density, heat
and amount of the ingredients
to be cooked.
• You can preserve the natural
taste of foods by cooking them
in their own juices without
adding a lot of spices, or with
no spices at all.
• Microwave ovens save energy.
Energy is only used when you
are cooking. There is no wasted
energy with a microwave.
• You need not worry if you forget
to let meat thaw. Microwave
ovens thaw out frozen foods
in a short time so you can start
cooking immediately.
• Foods preserve their nutrition
value thanks to shorter
cooking times.
• Cleaning is also easier compared
to conventional ovens.
Microwaving in theory
• Microwaves are a form
of energy similar to radio
and television waves. The
magnetron tube inside your
microwave oven produces
microwave energy. Microwave
energy diffuses in all directions
inside the oven, reflected
from the side walls and thus
penetrates into the food evenly.
The microwaves cause rapid
vibration in the molecules of the
food. This vibration creates the
heat that cooks the food.
• The microwaves do not pass
through the metal walls of
your oven. Microwaves can
pass through materials such as
ceramic, glass or paper.
Why do foods get heated
Most of the foods contain water
and water molecules vibrate
when they are subjected to
microwaves. Friction between
molecules produces the heat that
increases the temperature of the
food, thaws them if frozen, cooks
them or keeps them warm. As a
result of the heat build-up inside
the food
• Foods can be cooked with very
little or no oil;
• Thawing or cooking in a
microwave is much faster than
a conventional oven;
• Vitamins, minerals and nutrition
elements in the foods are
preserved;
• Natural colour and aroma of
the food do not change.
Containers suitable
for microwaving
Microwaves pass through
porcelain, glass, cardboard
or plastic but not the metals.
Therefore metal utensils or utensils
with metal parts cannot be used
in the microwave oven.
Microwaves are reflected
by metal...
...but they pass through glass
or porcelain...
...and absorbed by the foods.
Fire risk!
Never place metal or metal
covered containers in your
microwave oven.
Warning
Do not use your oven when
empty and without a tray.
This can damage the oven.
• Microwaves cannot penetrate
metal. Microwaves will reflect off
any metal objects in the oven
causing dangerous electric
arcing. Most heatproof
non-metallic containers are
suitable for use in a microwave
oven. However, certain
containers may contain
materials that are unsuitable
for microwaving. You can apply
the following test to determine
whether a container is suitable
for microwaving or not:
• Place the container you wish
to test empty in the oven along
with another container filled
with water.
• Operate the oven at high
power for one minute. If the
water has been heated and
the container you are testing
is cold, then it is suitable for
microwaving.
• On the other hand, if the
water remains cold and
the neighbouring container
heats up, this means that
the microwaves have been
absorbed by the container and
therefore subject container is
unsuitable for microwaving.
Glass containers
• Avoid using containers made
of very thin glass or lead crystal.
Heatproof glass containers are
suitable for use in microwave
ovens. On the other hand,
in the microwave oven avoid
using brittle glass containers
such as water and wine glasses
that may break as their contents
heat up.
