Description
PEF applies short, high‑intensity electric pulses to foods, inducing electroporation that inactivates microorganisms without significant heating.
Technical
The electric field disrupts cell membranes, creating pores that allow leakage of cellular contents. When the field exceeds a threshold, pores become permanent, leading to irreversible electroporation and cell death. The process is non‑thermal, preserving nutrients and sensory attributes.
