– If you are heating liquid in the MW, it could heat over the boiling point without any visible
signs of bubbles. After removing the dish a heat shock may cause sudden overflow and
burst of boiling liquid. You can prevent this by putting a spoon made of special plastic for
use in high temperatures or a glass stick in the dish with liquid before putting into the oven.
– Check the condition of the supply cord regularly.
– Prevent the supply cord to hang loosely over the edge of the working desk where children
could reach it.
– The supply cord must not be damaged by sharp or hot objects, open flames, must not be
immersed in water or bent over sharp edges.
– If you need to use an extension cord, it must not be damaged and correspond with the
standards in force.
– Do not use the appliance for any other use than the one it is intended for and described!
– The manufacturer is not liable for any damage cause by incorrect use of the device (e.g.
devaluation of food, burns, scalding, irradiation by microwaves, fire) and is not liable
for the warranties in case of breaching the precautions mentioned above.
II. INTRODUCTION TO MICROWAVE COOKING
How a microwave works
Microwaves are a form of energy similar to radio and television waves
and regular daylight. Everything radiates microwaves – kitchen sink, coffee pot, even
people. But microwaves spread through the atmosphere and disappear without effect. MW
is designed to utilize the microwave energy. Electricity is transformed into MW energy in
magnetron and microwaves proceed through the openings in the walls of the oven into
the food preparation space. Microwaves can not penetrate the microwave walls but can
penetrate materials such as glass, porcelain and paper, thus materials of which the ware for
microwave food preparation is made. Microwaves do not heat the dishes but the dishes may
be heated by the heat of the heated food. Microwaves are drawn by moisture in the food
where they cause vibration of the molecules of water
2450 times per second. The molecules rub against each other and create friction which
causes the heating of the food.
Very safe appliance
MW oven is one of the safest home appliances. If the door is opened, the MW automatically
stops its operation.
Factors affecting the cooking time
The cooking time is affected by several factors. The temperature of food and ingredients
used for cooking causes big differences in the cooking length. E.g. food preparation with
ice-cold food will last substantially longer than preparation of the same food with ingredients
whose temperature is room temperature. The cooking time is also affected by the set power.
III. HOW FOOD QUALITIES AFFECT MICROWAVE COOKING
Food density
Light, porous foods such as pastry and bread are prepared faster than heavy, dense foods
such as roast. When preparing porous foods in MW oven, make sure the outer parts do not
dry and crispen. Cover the outer parts with foil (for MW ovens) or cook at low power.
Food height
Top part of tall foods, namely when baking will bake faster than lower part. It is therefore
suitable to turn the food while cooking, sometimes several times.
