How PEF works for

roots, tubers and fruits

Elea Pulsed Electric Field systems use precise and targeted electrical pulses to open the cell membranes (electroporation) in raw products. It’s a clean, gentle and controlled process that can be used to benefit a broad range of products.

1 cell wall
2 water
3 cell components
4 cell membrane

The only part of the cell affected by PEF is the cell membrane.

The product enters the PEF system, and the cell transits into the PEF treatment area.

As the Pulsed Electric Field is applied, the cell membrane becomes charged, resulting in electrical compression and pore formation (electroporation).

Water and soluble solids are able to leak out of the newly opened pores. Valuable cell components cannot exit through the pores and are retained. The cell structure remains undamaged.

The cell is now softer, more elastic and much easier to process.
