Microwave processing uses dielectric heating to rapidly raise temperatures in foods, especially proteins, by exciting polar molecules.
Origin: United States (1940s) — North America
See full technique reference →Microwave ovens operate at 2.45 GHz, causing dipolar rotation of water molecules and ionic conduction that convert electromagnetic energy into heat within seconds. The rapid heating can reach 100 °C in 1–2 min for 100 g of water, but uneven heating and localized hot spots can lead to moisture loss, texture changes, and lipid oxidation.
