Description
Ohmic heating uses electric current to generate uniform volumetric heat within food.
Technical
By passing current through food, electrical resistance causes Joule heating, raising temperature rapidly and uniformly. The process inactivates microorganisms and denatures proteins while preserving heat‑sensitive nutrients due to short residence times.
