PEF Pilot Trials at Hochschule Geisenheim Confirm Promising Extraction Results

15. April 2026 - Together with Hochschule Geisenheim, Elea recently conducted a series of pilot-scale trials to investigate the impact of Pulsed Electric Field (PEF) technology on the extraction performance of various vegetables.

Evaluating Vegetable Extraction Performance at Pilot Scale

Elea's R&D Engineer Marc Schmidt and Laboratory Technician Teresa Siefken were on site to support the series of trials at Hochschule Geisenheim. Over two dedicated trial days, the pilot-scale results confirmed the findings previously observed in laboratory studies. The trials demonstrated increased juice yield, enhanced colour intensity, and consistently higher Brix values across the tested products. These outcomes provide strong evidence that the benefits of PEF technology can be reliably transferred from controlled laboratory experiments to practical processing conditions, highlighting its potential for industrial applications.

Strong Collaboration with Hochschule Geisenheim and Industry Partners

The successful trials were made possible through the close cooperation between Elea and the Department of Beverage Research at Hochschule Geisenheim University, led by Prof. Dr. Ralf Schweiggert. The project also benefited from access to advanced processing equipment provided by BLFT GmbH and Flottweg.

Elea greatly values the collaboration with Hochschule Geisenheim and its partners and looks forward to continuing joint research activities!
