Pulsed Electric Fields

Microbial inactivation through high intensity Pulsed Electric Fields (PEF) application is a new technology in food preservation. PEF has a minimal effect on food's temperature and quality and is suitable for foods such as fruit juice, apples, avocados, onions, and eggs.

PEF involves the application of short bursts of high voltage to a fluid food placed between two electrodes. It has the potential to increase energy use efficiency, as well as to provide microbiologically safe and nutritious foods with fresh-like quality.
