PEF can significantly enhance the quality of freeze-dried products by preserving more of the natural shape, flavour, aroma, and colour of the fresh produce.

PEF triggers electroporation, opening cell membranes in the treated product. This enhances internal diffusion, leading to improved mass transfer.

    Better shape retention

    PEF treatment results in a higher-quality product with improved shape stability and reduced shrinkage.

    Retain more flavour, aroma and colour

    The shorter drying times and improved process control provided by PEF allow the raw product to retain more of its original colour, shape, and flavour.

    Potentially save energy & increase capacity

    Shorter processing times make the production process more sustainable, resulting in energy savings and increased capacity.

    Better rehydration

    PEF treatment improves shape preservation, creating a more open product structure that enhances rehydration.
