What is Pulsed Electric Field (PEF) Technology?

Pulsed Electric Field (PEF) technology uses short, high-voltage pulses of electricity to treat materials, most commonly food and liquids, for various purposes, such as preservation, extraction, and sterilization. When an electric field is applied to a product, it creates temporary pores in cell membranes, a process known as electroporation. This disruption of the cell membrane leads to the release of intracellular contents and, depending on the application, results in either enhanced extraction or microbial inactivation.

PEF processing has emerged as a key innovation in several industries due to its ability to achieve non-thermal, energy-efficient, and sustainable processing. It preserves the quality and nutritional content of food, improves shelf-life, and reduces energy consumption, making it a compelling alternative to traditional thermal methods like pasteurization or sterilization.
