Microwave Oven
- The magnetron produces short
radio waves called microwaves
- These waves travel
through a wave
guide
- A fan like device called
stirrer that scatters the
waves throughout the
oven
- The waves bounce from wall to
wall until they enter the food
- The water
molecules in the
food are dipolar
- Have a positive charge at
one end and a negative
charge at the other
- Act as magnets as the
microwaves pass into the food
- The rapid vibration from
molecules creates heat
- Advantages- Warms up leftovers,
defrosts meats, freshens snacks,
cooks foods quickly.
- Has been around since 1945
- Acceptable dishes- plastic,
glass, microwaveable dishes.
- Foods that should not be microwaved-
eggs in shells, pancakes, deep fried foods,
large amounts of foods.
- The more food you cook in the
micowave, the less energy there is
for the food to absorb.
- Food cooks quickly and
has no tie to brown.
- Arrange food so that the thickest
is on the outside of the plate.
- The microwaves do not go through metals.
- Use potholders to avoid burns
- Removed food from the oven before it is totally
cooked, allows some microwaves to finish cooking.
- Heat is inside the food, so food does not stop
cooking when oven turns off.
- Foods at refrigerator and freezer
temperatures take longer to cook
- Density affects cook time
