What-does-a-microwave-oven-do-to-food, microwave ovens cook food using waves of energy that are similar to radio waves but shorter. these waves are remarkably selective, primarily affecting water and other molecules that are electrically asymmetrical — one end positively charged and the other negatively charged.. Microwave ovens are kitchen appliances that turn electricity into electromagnetic waves called microwaves. these waves can stimulate molecules in food, making them vibrate, spin around, and clash ..., a microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. this induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the ....

Also, one must avoid microwaving any food item in a metal container. the fact that metals reflect electromagnetic waves is the working principle of radar. if you feed an oven a metal bowl, most of the microwave energy, as though a metallic ship, will be reflected by it., how do microwaves cook food? how does a microwave turn electricity into heat? like this! inside the strong metal box, there is a microwave generator called a magnetron.when you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves.; the magnetron blasts these waves into the food compartment through a channel called a ....

What microwaving really does to your food... over 90% of households have microwave ovens. when i meet with clients i always ask them how they cook there food. inevitably, many people admit they do frequently re-heat food in their microwave. when ever i hear this i always tell my clients to immediately stop using the microwave to cook or re-heat their food., continued. but in most cases, using your microwave to cook food, if it’s covered tightly in a microwave-safe container with a minimal amount of liquid, is a nutritional win..

Microwaves destroy breast milk and vitamin b-12. the health benefits of vitamin b-12 are instantly negated once heated in a microwave. in a study published in the journal of agricultural and food chemistry, researchers decided to examine the effects of microwave heating on the loss of vitamin b-12 in foods like raw beef, pork, and milk.the results of the study show there was a 30 to 40 percent ..., conclusion. to wrap it all up, microwaves do not kill bacteria but what actually does kill bacteria is heat. the safest route to take is making sure that after defrosting food in a microwave oven or using styrofoam, make sure that you cook it thoroughly by allowing it to stay longer and cook more evenly or using a regular oven or convection oven to cook the food right through..

The food and drug administration (fda) has regulated the manufacture of microwave ovens since 1971. microwave oven manufacturers are required to certify their products and meet safety performance ...
