Then they pass through the
cooking containers to be
absorbed by the water
molecules in the food, all
foods contain water to a more
or lesser extent.
The microwaves cause the water molecules to vibrate
which causes FRICTION, i.e. HEAT. This heat then cooks
the food. Microwaves are also attracted to fat and sugar
particles, and foods high in these will cook more quickly.
Microwaves can only penetrate to a depth of 1½ - 2
inches(4-5cm) and as heat spreads through the food by
conduction, just as in a traditional oven, the food cooks
from the outside inwards.
MICROWAVING PRINCIPLES
Microwave energy has been used in this country to cook and reheat food since early experiments with RADAR in
World War ll. Microwaves are present in the atmosphere all the time, both naturally and manmade sources.
Manmade sources include radar, radio, television, telecommunication links and car phones.
CONVERSION CHARTS
HOW MICROWAVES COOK FOOD
In a microwave oven,
electricity is converted
into microwave by the
MAGNETRON.
The microwaves bounce
off the metal walls and
the metal door screen.
