- In cooking, radiation is the process where heat and light waves strike and penetrate your food. As such, there is no direct contact between the heat source and the cooking food. There are two main radiant heat cooking methods: infrared and microwave radiation.

Jun 14, 2021 · Infrared radiation is when the infrared light, emitted naturally by the burning wood or glowing charcoal of an outside grill, or artificially by the heating panel of your broiler, toaster, or infrared oven, heats both your cookware and your food.
Jan 22, 2021 · What is infrared technology? In short, the technology behind infrared cooking is the use of infrared radiation (IR), also referred to as infrared light: a type of electromagnetic radiation (or energy-carrying waves, which microwaves emit) generally not visible to the human eye.

Aug 8, 2021 · Microwave radiation is used to cook food. Reflection and polarisation also occur in microwaves. Microwaves are absorbed by water particles in the outside layers of the food, increasing the kinetic energy of the particles. Energy is then transferred to the centre of the food by conduction or convection.
Infrared radiation can be used to inhibit bacteria, spores, yeasts and mold in liquid and solid foods. The effectiveness of infrared inhibition depends on the amount of infrared energy, food temperature, wavelength, wave width, food depth, microorganism type, moisture content, and food material type.
Feb 10, 2021 · Radiation is when you feel the heat of your lover’s body under the covers without touching. Let’s be a bit more precise: 1) Conduction is when energy is transferred to the food by direct contact with the eneregy source. Grill marks are a good example of conduction. Heat is transferred to the grill grates and the hot metal brands the meat.
