Abstract
It has been shown that exposing biological cells to an electric field provides a potential to influence permeability of cell membranes and to induce structural changes and a local membrane breakdown. Based on this phenomenon called electroporation a broad variety of applications in food processing and bioprocessing have been studied since the 1960s (Doevenspeck, 1960; Sale and Hamilton, 1967; Flaumenbaum, 1968). In plant or microbial genetics an electroporation is used to induce foreign material such as DNA into cells. The process of reversible pore formation has to be perfectly controlled to maintain viability of the organisms during the application of the PEF. This principle can also be utilized to induce stress reactions and secondary metabolites biosynthesis, which can be desirable food constituents.
