Innovative food processing technology
Food processing with nanosecond Pulsed Electric Fields (nanoPEF) inactivates spoilage micro-organisms and pathogens without changes of original taste, flavor and nutrient content of the processed beverages with substantial reduction of CO2 emissions
PEF Technologies B.V. is a start-up company which has been founded in 2018. Our team unites highly skilled professionals in the field of pulsed power electronics. During the years of experience we have acquired a lot of unique “know how” knowledge in the building of nanosecond pulse generators for the generation of high current electron beams.
The problems of food and beverages preservation and reduction of energy consumption are daily problems and not new. Our solution is to apply nanosecond pulsed electric fields to the food and beverages preservation. After a number of initial tests on proof of principle concept we came to the conclusion on technical and commercial feasibility of food and beverages preservation with the use on nanosecond high voltage pulses (nanoPEF).
If you want to know more about our technology and how it could be beneficial for your business, we are glad to help. Please, fill in the contact form below and we will reach you back in a short time.
We present a non-thermal innovative technology of food processing involving the application of short duration high intensity electric fields (nanoPEF).Benefits of nanoPEF food processing:
- Undamaged nutritious and sensory quality of processed beverages.
- Fully electrical powered system.
- Environmental friendly technology, substantial reduction of CO2 equivalent emission.
- Extended shelf life of processed liquids up to 1 month.
- Compact design and easy installation.
- Wide range of machines for any production volume.
- Customized solutions are possible.
What we offer
The application of nanoPEF technology is not limited by a certain product type. It can be perfectly applied to any type of homogeneous product, e.g. juices, yogurts, wines, etc.
There is no doubt that pasteurization provides a safe product with a relatively long shelf-life but often fails to preserve on bio-accessibility and bio-availability of nutritious components as any heat treatment. Our solution does not deteriorate the original fresh taste, color, flavor and all the nutritious content of the processed liquid. This is specially important for infant formula since its positive effect on the immune system of babies is strongly dependent on protein quality.
Consumer behavior is changing the fruit juice industry. According to the recent market researches, juices and chilled juices, in particular, are experiencing growth in sales while ambient and FC (from-concentrate) juices are experiencing a decline. Pasteurization technology, which is widely use for juice preservation, changes it quality and taste. Our solution offers extended shelf-life of fresh-pressed juice and remains unchanged its original taste and nutritiouse value.
Nanosecond PEF treatment based on phenomenon known as “electroporation” of cell membranes. As a result, it inactivates different kinds of vegetative spoilage and pathogenic microorganisms without deterioration of proteins, vitamins, antioxidants and pigments. The uniqueness of our idea is the use of nanosecond pulses instead of microsecond ones with much higher electric field intensity.
The main essence of our approach implies in the introduction of the new generator topology which is more practical and cheaper for development compared to any existing models. Our invention goes beyond the present state of art in the pulse generator development on the commercial scale.
High voltage nanosecond pulses are applied to the electrodes which are situated in the treatment chamber. The liquid is pumped through electrode arrangement and exposed to the pulsed electric fields. As a result, after processing with nanoPEF, the product retains its original quality at a level of bacteria inactivation that meets the standards of the food industry.
