20120918 TOP- bv - Mrs. Myriam Knopf – Technoproject Pulsed Electric Field (PEF) as accelerator for extraction

TOP is specialized in development and design of innovative food processes and equipment as well as innovation management services. PEF was originally developed for food conservation. TOP-bv‘s PurePulse technology is the only commercial large scale technology to pasteurize food below 40°C. Its high pulse energy makes PurePulse also very suitable for accelerating extraction of components from biomass. The principle is increasing energy levels locally, which creates pores in the cell wall, repaired later by the cell, until cell rupture. The cell releases components that can be captured by suitable extractants.

NL GUTS members Cosun, FrieslandCampina, Purac and Vion participated in this Technoproject. Variabels were field strength, pulse frequency and temperature.

In all tested applications the component extraction efficiency was considerably increased and the juice yield greatly improved. Further research is planned to identify process optima. www.top-bv.nl
