PEF accelerates air drying, saves energy and captures more of the natural shape, flavour, aroma and colour of the fresh produce.

PEF induces electroporation which opens cell membranes
in the treated product. This increases the internal
diffusion resulting in improved mass transfer.

    Save energy, increase capacity and reduce process time

    The production process becomes more sustainable with shorter process times, providing energy savings and an increase in capacity

    Retain more flavour, aroma and colour

    Shorter drying times and better process control enabled by PEF mean that the raw product retains more of its original colour, shape and flavour.

  • Dried kiwi slices on dark background

    Better rehydration

    Better shape preservation with PEF treatment produces a more open product structure, enhancing rehydration.

  • Dried beetroot slices on a dark surface.

    Better shape retention

    PEF treatment produces a higher quality product with increased form stability and less shrinkage.

40 % shorter drying of air-dried tomatoes

In this example, tomato slices were dried at 50°C. A noticeable difference in moisture content over time was observed, demonstrating a 40 % shorter drying time after PEF treatment.

Yellow onions dry faster, gentler, with fewer quality losses

PEF treated yellow onions dried at 75°C have nearly the same drying time compared to an untreated sample dried at 85°C!

Moisture content [%]

time [min]

Rehydration rate of yellow onions doubled with PEF

The open cell structure caused by PEF improves rehydration. In this example the final water uptake for the PEF-treated sample is with 66.8 % nearly twice as high as for the untreated sample with 35.1 %.
