Abstract: Pulsed electric fields (PEF) became more and more popular in different applications for processing of biomaterials. The PEF technology is non-thermal and it uses short pulses of electricity to induce electroporation in cell membrane. Electroporation allows creating permanent or temporary pores and increasing the permeability of the cell membrane. The effects of electroporation may depend on the size of cells, their orientation and spatial distribution in space, passive and active electro-physical parameters of cells, pH of media and presence in tissue osmotic agents. Nowadays, electroporation is accepted as promising technique with applications in biomedical, biotechnological and food engineering fields. This presentation discusses fundamentals of electroporation of the membrane, various models, mechanisms for development of electroporation and simulations of electroporation, electroporation in ensembles of cells, and in biological tissues. Techniques to detect electroporation, pulse generators and producers of equipment are discussed. Finally applications of electroporation for assistance of different processing operations (solid/liquid extraction and expression, drying, cooling, freezing, thawing and crystallization) are also presented.
