Microwaves provide an energy-efficient way to heat food quickly and easily; however, they don't always heat food evenly and can potentially be harmful if food is not heated properly. Microwaves are useful for preparing convenient meals and for defrosting meats immediately before being transferred to the oven or grill.Know More
According to The University of Texas Health Centers Northeast, carcinogenic compounds can potentially be released when cooking steak or hamburger in a pan or on the grill, but microwaving meats beforehand helps to prevent this.
Microwaves have their limitations. Only "microwave-safe" dishes should be used in the microwave; otherwise, unsafe chemicals like polyvinyl chloride may contaminate the food. According to foodsafety.gov, it’s important to follow directions on the boxes of convenient meals because it can be easy to undercook or unevenly cook the food in the microwave. Covering, stirring and rotating food may be necessary to ensure it is prepared safely. If these directions are ignored, the food may not be heated fully and bacteria will not be killed, causing food-borne illness. It’s important to also recognize that a microwave is not the same thing as a convection oven or a toaster oven.
The wattage of a microwave is also important — if the microwave’s wattage is lower than recommended, the food may not be heated entirely within the recommended time frame. If it is unclear whether a food has been heated properly, use a food thermometer to check the temperature.Learn more about Inventions
Prior to their use in the microwave oven, microwaves were used as part of radar communication, and it is in this capacity that an American named Percy Spencer inadvertently discovered that microwaves could be used to cook food. During WWII, Spencer was working on radio transmitters for Raytheon as part of the 1945 war effort.Full Answer >
The first microwave oven was built in 1947. Sometime around 1946, Percy Spencer, while working for Raytheon, discovered that a magnetron developed to jam radars during World War II also melted the chocolate bar in his back pocket. Corn kernels were some of the first foods Spencer tested, and when they popped, he began attempts to heat other foods using the magnetron.Full Answer >
The automobile was invented to provide a form to transport people and cargo that was quicker and more convenient than those that existed at the time, such as horses, horse-drawn carriages, trains and boats. In addition to the automobiles basic benefit of faster, private transportation, the automobile also provided economic security and job opportunities for those working in the automobile industry.Full Answer >
The microwave oven was patented on October 8, 1945 by the company Raytheon. At the time, it was called the Radarange. It wasn't until 1967 that the microwave was more affordable and reasonably sized.Full Answer >
