Research Breakfast: Pulsed electric field - Principles and Applications
Welcome to a presentation on the topic of pulsed electric field - principles and applications with Federico Gomez, Professor at the Division of Food and Pharma at Lund University.
On the first Friday of every month, Biotech Heights invites you to a breakfast and lecture on a topic of relevance to biotechnology, the food sector and materials! This seminar series is a collaboration with the LTH Profile Area Food and Bio.
The event is a space to learn something new, discuss research with your peers and build your network! We encourage questions, queries and new perspectives!

Pulsed electric field - Principles and Applications
Pulsed electric field (PEF) technology uses short electrical pulses to induce physical and biological changes in food and biological materials. This presentation introduces the fundamental principles of PEF, key processing parameters, and interactions with food components. The focus then shifts to cellular materials and electroporation, explaining how membrane permeabilization can be reversible or irreversible.
Applications of irreversible PEF, including enhanced extraction and mass transfer, will be presented alongside emerging applications of reversible PEF. Particular attention will be given to how surviving cells may respond to PEF through changes in metabolism, stress responses, and subsequent cellular behaviour, and how these responses can be exploited in applications such as fermentation.
