Microwave ovens are an easy way to heat up food. But they do have a few rules that you should follow to keep your family safe and prevent injury:
Never put styrofoam, takeout containers, or metal items in a microwave. These items can melt and cause burns or even fires.
Avoid using a microwave to reheat frozen foods or hot beverages (they can actually cause the liquid to break down). The heat will also damage the delicate skin of fresh produce.
How microwaves work
A microwave works by reversing the electric field 2.5 billion times a second in water molecules. Those molecules have one positively charged end and two negatively charged ends, says John Bloomfield of the University of Texas at Austin.
The positive end of the water molecule aligns itself with the microwave’s electrical field and the negative end tries to move away from it, he explains. But the electric field twists the water molecule back and forth, which can heat up the atoms inside the molecule.
Sensor cooking mode: This feature senses the amount of heat needed to cook a particular item and automatically adjusts the power level for perfect results every time.
Convection cooking mode: A microwave also features a fan that circulates the air inside the cavity and keeps it warm, similar to a traditional convection oven. This allows for the best results with a wide variety of dishes.
A microwave oven’s exterior is typically made of a plastic or stainless steel finish, and there are many different models to choose from. But the key is to look at what functions and features a model has, and how easy it is to operate.
