PEF can dramatically improve the quality of freeze-dried products, capturing more of the natural shape, flavour, aroma and colour of the fresh produce

Better shape retention

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

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.

Potential energy savings, increase capacity & reduce process time

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

Better rehydration

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

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

Discover how PEF can reduce food waste and enable new product opportunities

PEF can enable new dried product opportunities for producers looking to make better use of their surplus or second-class produce.
