Like most of today’s great inventions, the microwave oven was a by-product of another technology. It absolutely was after a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer using the Raytheon Corporation, noticed something very unusual. He was testing the latest vacuum tube known as the magnetron, when he learned that the candy bar in his pocket had melted. This intrigued Dr. Spencer, so he tried another experiment. These times he placed some popcorn kernels at the tube and, perhaps standing slightly farther away, he watched through an inventive sparkle in the eye because the popcorn sputtered, cracked and popped across his lab.
Another morning, Scientist Spencer decided to place the magnetron tube near an egg. Spencer was joined with a curious colleague, and they also both watched because the egg began to tremor and quake. The rapid temperature rise within the egg was causing tremendous internal pressure. Evidently the curious colleague moved in for a closer look just like the egg exploded and splattered hot yolk all over his amazed face. The facial skin of Spencer lit up with a logical scientific conclusion: the melted chocolate bar, the popcorn, and today the exploding egg, were all attributable to exposure to low-density microwave energy. Thus, if the egg may be cooked that quickly, why not other foods?
A lot of people use microwave ovens like a convenient way to thaw, cook and reheat food. Many people have concerns, however, about the effect of microwaves on their health and also on the safe practices of the foods.

Many individuals who use microwave ovens say they’ll “nuke” their food. This reference to nuclear energy is incorrect and misleading. Microwaves are a variety of radiofrequency electromagnetic energy. These are generated electronically. They cannot originate from radioactive sources and they cannot cause food or even the oven itself for being radioactive. Microwaves are widely-used to detect speeding cars, to send telephone and tv communications, and treat muscle soreness. Industry uses microwaves to dry and cure plywood, to cure rubber and resins, to raise bread and doughnuts, and to cook potato chips. But the most frequent consumer using of microwave energy is due to microwave ovens.
The Food and Drug Administration (FDA) has regulated the manufacture of microwave ovens since 1971. On such basis as current understanding of microwave radiation, the Agency believes that ovens that fulfill the FDA standard and so are used in line with the manufacturer’s instructions are safe for use. Microwave ovens can play a huge role at mealtime, but special care must be taken when cooking or reheating meat, poultry, fish, and eggs to be sure they may be prepared safely. Microwave ovens can cook unevenly as well as leaving “cold spots,” where harmful bacteria can survive. Because of this, it is very important to make use of the following safe microwaving tips to prevent foodborne illness.
Arrange foodstuffs evenly inside a covered dish and then add liquid if needed. Cover the dish having a lid or plastic wrap; loosen or vent the lid or wrap to let steam escape. The moist heat that may be created may help destroy harmful bacteria and ensure uniform cooking. Cooking bags in addition provide safe, even cooking.
