Description
Pulsed electric field extraction is a non‑thermal method that uses high‑voltage pulses to create temporary pores in plant cell membranes, releasing juice efficiently.
Technical
The electric field induces electroporation, causing rapid ion fluxes and membrane destabilization. This process allows intracellular solutes—sugars, vitamins, phenolics—to diffuse into the surrounding medium without significant heating, preserving heat‑sensitive nutrients. The short pulse duration (1–10 µs) limits joule heating, keeping product temperature below 50 °C.
