The power of PEF

Mark de Boevere

International Potato Processing & Storage Convention (IPPSC) 2015

  • PEF

Mark de Boevere from Pulsemaster delivered a comprehensive overview of the latest advancements in the development of Pulsed Electric Field (PEF) equipment at an industrial scale for potato processing. His presentation was titled “Systems Using Pulsed Electric Field (PEF) Technology – An Excellent Alternative for Preheaters in the Potato Industry.”


The presentation effectively highlighted the benefits of Pulsed Electric Field technology, detailing enhanced sugar extraction levels, improved cutting, reduced feathering, and a smoother cutting surface. It also emphasized reduced frying time and improved texture and crispiness of potato products. Potatoes processed with Pulsed Electric Field become more homogeneous, evening out the structure and consequently reducing seasonal variation.

The audience engaged actively, posing numerous questions about the pulse generator principles Pulsemaster employs in manufacturing turn-key PEF systems for the industrial processing of solids like potatoes to produce French fries and crisps.

The Convention

This three-day event was held from June 17th to 19th, 2015, at the Radisson Blu Hotel in Bucharest, Romania. It was jointly organized by Potato Processing International and Potato Storage International magazines. The conference garnered significant interest from the potato industry.


The event’s central theme was “Dynamic Potato Industry Solutions – Looking into the Competitive Future of Potato Processing and Storage.” One of the significant topics covered at IPPSC 2015 was Pulsed Electric Field (PEF) technology for potato processing.An important topic covered by IPPSC 2015 was, among others Pulsed electric field (PEF) technology for potato processing.

PEF Technology

Pulsemaster’s PEF technology induces poration in potato cells, leading to cell disintegration and making PEF systems an excellent alternative to preheaters in the potato industry. The conference presented several examples of potato applications of electroporation to enhance cell disintegration and improve mass transfer in the extraction of compounds of interest in potato processing.
