wat is micro wave oven...it's use...is it hygenic 2 cook in it?

Answer 1

A microwave oven uses microwaves to heat food, they cook food in an amazingly short amount of time are also extremely efficient in their use of electricity because a microwave oven heats only the food -- and nothing else.

Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion -- heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. Metal reflects microwaves, which is why metal pans do not work well in a microwave oven. The radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. No heat has to migrate toward the interior by conduction. There is heat everywhere all at once because the molecules are all excited together. There are limits: radio waves penetrate unevenly in thick pieces of food (they don't make it all the way to the middle), and there are also "hot spots" caused by wave interference, but you get the idea. The whole heating process is different because you are "exciting atoms" rather than "conducting heat."

The air in the oven is at room temperture, so there is no way to form a crust. That is why microwavable pastries sometimes come with a little sleeve made out of foil and cardboard. You put the food in the sleeve and then microwave it. The sleeve reacts to microwave energy by becoming very hot. This exterior heat lets the crust become crispy as it would in a conventional oven.

Cooking foods in a microwave oven does not alter them other than to heat them. There are no known effects on humans from microwaved food as opposed to foods heated by other means.

Answer 2

Microwaves have a magnetron which generates a high frequency radiowave. The radiowaves are absorbed by the food in the oven and this raises the temperature of the food. It is very hygienic. Always cover the food being heated with a microwave safe lid or a heavy paper towel. A common use is re-heating refrigerated food. Microwaves are very energy efficient and for most purposes, much faster than a conventional oven. They come in various sizes. Always get a microwave with a rotating tray and variable powerr settings. It is easy to make just one cup of tea or coffee in the microwave - no hassle of heating the water in a pan on a gas or electric range. Good for thawing most frozen food also.

Answer 3

A microwave oven is perfectly good and safe to use and hygeniec as well. You just have to learn a new way of cooking. Micro's cook by using microwave radio energey that energizes the water molecules in food and excites them to rub together to creat the cooking heat. I have used microwave ovens for over 30 years and they are a great and fast way to cook.

Answer 4

Micro wave oven is an electonic device for cooking food.There r many advantages of cooking food in it it is hygenic but food should not be over cooked,it has some limits also like time & temperature management must be proper.Uses of microwave oven are:-1.cooks food faster than cooking gas with less oil.2.make pastry,biscuits,cakes & other bakery items.3.Italian dish like pasta,pizza R coked in it nicely.4.U can grill sandwiches,toast i it etc.5.lastly kheer & halwa R also made fastier in it.

Answer 5

Ok first answer sucks. If microwaves changed food THAT much, they would NOT be sold for use in cooking/reheating food. There's nothing wrong with cooking food in a microwave. It heats differently than an oven, from the inside out, but it doesn't really change the structure, or whatever, of food.

Answer 6

very hygenic,rapid and easy !!!microwaves cook foods swiftly and easily,in a fraction of the time stove or oven cooking would take.meats dont brown as well,tho.very hygenic,far easier to clean than a conventional oven.

Answer 7

Hygienically it is very good but it is said that it disturbs the very fabric of the foods in such a way that our body is unable to accept that ultimately it is being advised that it should not be used either for cooking or for heating various food items.

Answer 8

a microwave(thats what i call it) heats up food very quickly (a piece of bread in 10 secs, steak in 1 minute) and is generally ver clean. Try going to Google.com/images and type it in (you can see what it looks like)

Answer 9

it is useful. u shud use proper cooking vessels. hygiene depends on how u maintain it. it is harmless if used safely. we are using for last 2 years with no difficulty..initially we had some difficulty in timings and power settings but u can learn with trial and error
