PEF Systems:A Cost-effective and Innovative Processing Technology

摘要

APEF is a non-thermal technology for food processing based on the application of repetitive, short electric field pulses to the food. This creates miniscule holes in membranes of the plant cells, which makes the cells porous and facilitates transportof water and other valuable compounds. This technology induces poration of membranes of potato cells, leading to cell disintegration. A typical PEF system for potato processing consists of a high voltage pulse generator and a treatment chamber through which the potatoes flow inwater. In the treatment chamber the high voltage pulses are applied. PEF technology has also been tested and validated for other applications such as fresh fruit juices, tomato processing, olive oil and red-wine making.
