Description
Heating using radio waves
Technical
Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material. At higher frequencies, this heating is caused by molecular dipole rotation within the dielectric.

Wine Analogy
Like flash-pasteurization in winemaking, dielectric heating rapidly alters molecular structures without prolonged heat exposure
Coffee Analogy
Similar to microwave-assisted drying of coffee beans which preserves volatile aromatics
Perfume Analogy
Comparable to enfleurage where rapid heat extraction captures fragile top notes
Culinary Applications
