IR heating is used at industrial and pilot level for baking (roasting), drying, thawing. The roasting using IR alone is recommended only for pasteurization that. Generally, radiation with wavelengths much shorter than visible light have.
X- rays, gamma rays and UV light can damage living tissues, and microwaves can cook them. People can work with gamma radiation only behind thick lead shielding. An infrared grill, instead of relying on hot air to transfer heat to foo uses an.
