What You Need to Know
Dielectric heating in microwaves excites polar molecules, raising temperature uniformly within the field. Induction generates eddy currents in conductive cookware, heating the surface via resistive losses. Radio‑frequency penetrates deeper, gelatinizing starches, while plasma ionizes gases, sterilizing surfaces. These processes alter molecular structures, accelerating Maillard reactions and lipid oxidation kinetics.
The Science
Primary Reaction
Rapid dielectric heating, eddy current induction, and plasma ionization leading to protein denaturation, starch gelatinization, Maillard browning, and lipid oxidation
