●
Microwave ovens cook food using microwave
energy that is similar to naturally occurring radio
waves. Normally, these “waves” would fade
as they dispersed into the atmosphere but in
a microwave oven they are concentrated onto
the food causing it to heat up.
●
Microwave energy cannot pass through metal
– so it cannot escape from inside your
microwave oven – but it can pass through
materials like glass, porcelain, plastic and paper.
These materials are used in the manufacture of
microwave safe cooking equipment.
●
Microwave safe cooking equipment will still get
hot as the food it contains heats up.
The microwave energy focuses on the moisture
in the food causing lots of tiny vibrations. The
vibrations get so great that the moisture, and the
food heats up. (Fig 1)
checking your cooking utensils
Most heat-resistant, non-metallic cooking utensils
are safe to use in your microwave. If you are not
sure if you can use a utensil in your microwave,
follow this simple test:
1.
Put the utensil into the microwave next to a
cup of water – use a cup that you know is
microwave safe. Close the door.
2.
Turn the microwave on for 30 seconds only.
3.
After 30 seconds, carefully check to see if
the water has warmed up.
If the water has not warmed up but the utensil
has, the utensil is not microwave-safe and
should not be used in the microwave.
4.
Do not use your hands to touch the utensils as
it may already be hot.
