The Breville also makes it simple to customize based on the size, weight, and nature of the food you’re cooking. There’s even a reheat option for pizza. Alternatively, you can leave it up to the Breville’s sensor to detect moisture and temperature and accurately reheat. When we tried this in our testing of beverages and with our own lunches, it was surprisingly accurate.
This GE microwave oven with a 16-inch turntable proves you don't need to spend a bundle to get perfectly "baked" potatoes, steamed broccoli, or evenly heated mac 'n cheese. Thanks to a smooth control panel with lettering that contrasts well with the background, it's super easy to read the display and wipe it clean. If stainless steel isn't your style, this model also comes in black and white. 
Reviewers can’t contain their delight about this microwave’s Genius Sensor, which automatically adjusts the time and power based on the food type. “It feels very futuristic to press the Sensor Heat and let the microwave figure out on its own how long it should cook for. Most of the time, it’s dead-on, too, which is nice,” praises one commenter. “It’s pretty much impossible to overcook something,” writes another. Others note they “have had nothing boil over” and it “cooks super evenly. The days of half-molten-half-frozen food are gone.” Its modern exterior is another strong selling point. “The stainless steel looks very sleek and nice and will fit in with most kitchens,” one says.

Any form of cooking will destroy some nutrients in food, but the key variables are how much water is used in the cooking, how long the food is cooked, and at what temperature.[44] Nutrients are primarily lost by leaching into cooking water, which tends to make microwave cooking healthier, given the shorter cooking times it requires.[45] Like other heating methods, microwaving converts vitamin B12 from an active to inactive form; the amount of conversion depends on the temperature reached, as well as the cooking time. Boiled food reaches a maximum of 100 °C (212 °F) (the boiling point of water), whereas microwaved food can get locally hotter than this, leading to faster breakdown of vitamin B12. The higher rate of loss is partially offset by the shorter cooking times required.[46]
Different microwaves are designed for different locations. A countertop microwave sits on top of your kitchen counter. An under-cabinet microwave is mounted beneath your drawers-cabinet-organizers/4044_623679_1032619_1075864'>kitchen cabinets, keeping your counter space clear. An over-the-range microwave is mounted over a range or stove. Microwaves of this type often have built-in exhaust fans and lights.
Microwave ovens produce heat directly within the food, but despite the common misconception that microwaved food cooks from the inside out, 2.45 GHz microwaves can only penetrate approximately 1 centimeter (0.39 in) into most foods. The inside portions of thicker foods are mainly heated by heat conducted from the outer 1 centimeter (0.39 in).[38][39]
The Toshiba has an easy-to-use digital interface, with one key feature that helps it stand out from much of the competition: a mute button. Since this model doesn’t stop beeping when you open the door, we appreciated having the option to mute the beeping entirely. The Toshiba also has six preset cooking functions for popcorn, potatoes, pizza, frozen vegetables, beverages, and reheating a dinner plate. It has one-touch start controls from 1 to 6 minutes, and a plus-30-seconds button so you can quickly add extra time. Also, its lock function prevents kids from accidentally operating the machine (you simply hold the stop/cancel button for 3 seconds to lock or unlock the door). This model also has several other features that other microwaves we tested lacked, including a memory function (that saves up to three customized cooking times and power levels) and a multistage cooking function (that allows you to set two different cooking times and power levels to operate in succession), but we don’t think most people will use these often.
The effect of microwaving thin metal films can be seen clearly on a Compact Disc or DVD (particularly the factory pressed type). The microwaves induce electric currents in the metal film, which heats up, melting the plastic in the disc and leaving a visible pattern of concentric and radial scars. Similarly, porcelain with thin metal films can also be destroyed or damaged by microwaving. Aluminium foil is thick enough to be used in microwave ovens as a shield against heating parts of food items, if the foil is not badly warped. When wrinkled, aluminium foil is generally unsafe in microwaves, as manipulation of the foil causes sharp bends and gaps that invite sparking. The USDA recommends that aluminium foil used as a partial food shield in microwave cooking cover no more than one quarter of a food object, and be carefully smoothed to eliminate sparking hazards.[58]

Microwaves generated in microwave ovens cease to exist once the electrical power is turned off. They do not remain in the food when the power is turned off, any more than light from an electric lamp remains in the walls and furnishings of a room when the lamp is turned off. They do not make the food or the oven radioactive. Compared to conventional cooking, the nutritional content of some foods may be altered differently, but generally in a positive way by preserving more micronutrients - see above. There is no indication of detrimental health issues associated with microwaved food.[66]
Ever wondered how microwaves heat up food so quickly and efficiently? These appliances contain a part called a magnetron, which uses electricity to create high-powered radio waves. The waves are pushed into the microwave’s interior, where they bounce off the metal walls and penetrate whatever food you’re cooking. The turntable spins to help the waves hit the food from all angles, and this process makes the molecules in the food vibrate, warming them up. However, one of the downsides of microwave cooking is that radio waves can only travel a few centimeters into your food, so larger items don’t always cook evenly.
There are, however, a few cases where people have been exposed to direct microwave radiation, either from appliance malfunction or deliberate action.[67][68] The general effect of this exposure will be physical burns to the body, as human tissue, particularly the outer fat and muscle layers, has similar composition to some foods that are typically cooked in microwave ovens and so experiences similar dielectric heating effects when exposed to microwave electromagnetic radiation.

The microwave frequencies used in microwave ovens are chosen based on regulatory and cost constraints. The first is that they should be in one of the industrial, scientific, and medical (ISM) frequency bands set aside for unlicensed purposes. For household purposes, 2.45 GHz has the advantage over 915 MHz in that 915 MHz is only an ISM band in some countries (ITU Region 2) while 2.45 GHz is available worldwide.[citation needed] Three additional ISM bands exist in the microwave frequencies, but are not used for microwave cooking. Two of them are centered on 5.8 GHz and 24.125 GHz, but are not used for microwave cooking because of the very high cost of power generation at these frequencies.[citation needed] The third, centered on 433.92 MHz, is a narrow band that would require expensive equipment to generate sufficient power without creating interference outside the band, and is only available in some countries.[citation needed]
When shopping for the right model, consider the size, price, and type (countertop or over-the-range), depending on your kitchen space. Over-the-range microwaves are usually mounted over your stovetop, and they have a light and ventilation underneath. Depending on the model, you can also have the countertop or over-the-range microwave built into your kitchen setup. The options are limitless, fam.
If you really want microwave power levels that function accurately, look for a microwave with an inverter. What is an inverter microwave? Essentially, it uses a different type of microwave production that actually does change the power levels and heating. Set power to 5, and the inverter will make sure heating is at 50%. Other types of microwaves will use a cycling method, where the power is always set to 100% but at level 5 it cycles half as much as at level 10. Inverter technology tends to make power levels much more effective and sensible, but either way it’s important to know what you’re getting into.
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.[1] 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 outer 25–38 mm (1–1.5 inches) of a homogeneous, high water content food item.
