International Students from the ISU Program Explore PEF Technology at Elea

28.July 2025 — Last week, we had the pleasure of welcoming a group of international students from the International Summer University (ISU) program at Hochschule Osnabrück, accompanied by Dr. Lusani Norah Vhangani, PhD, to Elea.

Hands-On Experience with the Elea PEF Advantage B1 System

As part of their academic focus on food processing, technology, and innovation, the students participated in practical experiments using Elea’s PEF Advantage B1 system. Working with sweet potatoes, they explored how different PEF intensities influence chip production, evaluating improvements in cutting force, oil uptake, and colour after frying.

Investigating Extraction and Microbial Inactivation

In further trials, they used the PEF Pilot Dual system to explore enhanced extraction processes and microbial inactivation. By comparing untreated, PEF-treated and thermally treated samples, they were able to assess the benefits of Pulsed Electric Fields over conventional methods in terms of yield and pasteurization efficiency.

Industry Insight at Wernsing Feinkost GmbH

The program also included a visit to Wernsing Feinkost GmbH in Essen, where the students toured industrial facilities equipped with Elea PEF systems, giving them valuable insight into real-world applications of the technology at production scale.

Inspiring the Next Generation of Food Engineers

We truly enjoyed hosting such an enthusiastic and curious group, and we’re proud to contribute to the development of the next generation of food engineers by sharing our expertise and passion for innovative food processing solutions. Thank you to the students from the ISU program for visiting us in Quakenbrück!
