Microwave oven Use instructions
Paper towels
Use when reheating to cover food and absorb any fat. Use only for
short cooking times and under constant.
Ordinary plastic
Only if the plastic is suitable for cooking into the microwave. Follow
the instructions of the manufacturer. Should be stamped with the
mark for use in microwave oven. Some plastic containers are defor-
med when the food placed inside heat. Bags for cooking and sealed
plastic bag should be punched as indicated on the package.
Thin Plastic film
Only the one suitable for cooking in microwave oven. Use to cover
food during cooking and maintain moisture. Make sure the plastic

Do not use aluminium containers into the microwave oven, paper container with metallic handle,
metallic utensil, paper bags, polystyrene container, polyurethane or wood, that could damage the
appliance and could be harmful to food.
MAIN CHARACTERISTICS OF A MICROWAVE OVEN
The operating principle of a microwave oven is the use of magnetic waves to cook food.
The heart of the technology is a device that can generate electromagnetic waves that led into the
microwave oven heats the water molecules into the food. Water molecules are agitated and produce
heat that spreads uniformly reaching the deeper layers of the food.
Food cooks more quickly and evenly when the water content is more important. Indeed for example
vegetables need only few minutes, depending on the quantity, precisely because of the quantity of
water.
Compared to traditional cooking methods, which can burn more easily foods, with the microwave
oven that does not occur, if the advice on cooking times are applied.
The main advantages of microwave ovens are a part of the reduced cooking time compared to tra-
ditional cooking, with a significant energy saving. Exposure of food at high temperatures is limited,
for a better nutritional properties.
The microwave oven is also very useful to defrost and reheat food.
Cooking in a microwave oven is safe, does not produce permanent changes in the molecular struc-
ture of foods.
The downside of cooking in the microwave is the difficulty of assaying the exact cooking time for
each food.
