How does a microwave work?
microwave furnaces revolutionized the way we eat. Cooking incredibly fast compared to conventional furnaces, the microwave will also change healthy food into "fast food". Surprisingly, we can thank radio waves .
The microwave generates radio waves in the range of 2.5 Gigahertz. This spectrum lies between the radio waves of FM and the infrared beam, the latter whose border on the detectable light at the red end of the visible light. The microwave radio waves have favorable properties in the fact that they are absorbed by food - or liquids, fats and sugars. In other words, microwave radio waves are excited by the atoms that make up food. This results in evenly and quickly cooked food, all things are the same. In fact, some types of food do not allow the same penetration of radio waves, resulting in "cold spots". This is a concern for poultry, meat and eggs, and we can survive bacteria in uncooked areas.
To ensure that the food is cooked evenly in a microwave, some experts recommend coverage of food with a ventilated lid or microwave with a microwave. Thanks to this method, hot steam is placed under the lid or wrapping, raising the temperature to kill any bacteria and help cook the food more evenly. If cooking a large piece of meat, cooking at 50% force for a longer period of time can bring better results. One can also use a meat thermometer to ensure that the food is cooked at the right temperature.
Themicrowave is probably used more often to re -warm residues or frozen foods. Unlike the conventional oven that needs to be preheated, the microwave does not lose energy by heating the air inside the oven. Only food is heated. Plastic, ceramics and glass are also not absorbed by microwave radio waves. For this reason, some meals come with microwaveWith a reflective "browning list" for heat reinforcement in a particular area, for example, to brown the bottom of the pizza or the upper part of the pastry.
Because the microwave does not heat the container, it is easy to assume that the food is colder than it really is. Be careful not to burn with foods taken from the microwave. Experts warn to be particularly careful with children's bottles. The bottle might seem well to the touch, while the liquid inside could be close to the boil. Heating children's bottles on a pan with warm water can take several minutes longer, but for your child it is safer in the long run. If you are using a microwave to warm up the bottle, always try the milk or the pattern on the wrist before giving it to the child - a ritual that should be used even when heated the bottle on the stove.
suddenly people are afraid to eat food cooked by radiation until it was understood that all heat is radiation. However, it is recommended to become 20 inches (51 centimeters) or more of the microwave during cooking. If radiation leaks, it will minimize the exposure. If your microwave door stops clicking correctly, it is time to have them repaired or replaced. Meanwhile, use a conventional oven and avoid the operation of a microwave that you know is escape or defective.
