Other commonly used processes using high temperature, such as heat pasteurisation, affect food quality more negatively.<\/p>\n<p>The PEF mechanism is called electroporation and based on the following steps:<strong><sup>1<\/sup><\/strong><\/p>\n<ul>\n<li>Very short electric pulses of high voltage are applied to the food.<\/li>\n<li>Small pores are formed in the cell membrane of the food by the electric pulses without damaging the cell compounds, such as vitamins.<\/li>\n<\/ul>\n<p>Another application, where many advantages have been seen already is the <strong>pre-treatment for drying. <\/strong>PEF is creating small whole in the membrane of the biological cells causing an easier extraction of water. As a result, reduced process conditions in terms of temperature and time can be used for the drying process.<strong><sup>2<\/sup><\/strong><\/p>\n<p>When PEF is used for <strong>juice preservation<\/strong>, the electric pulses make pores in the cell of microorganisms such as <em>Salmonella typhimurium<\/em> or <em>Escherichia coli <\/em>and inactivate them. This way, fresh juice can be stored longer.<strong><sup>1<\/sup><\/strong><\/p>\n<p>When PEF is used for <strong>extraction<\/strong>, the pores in the cells make the content more easily accessible to produce for example puree or juice.<strong><sup> 3<\/sup><\/strong><\/p>\n<p>A short <a href=\"https:\/\/www.youtube.com\/watch?v=wnZuLzhh0b8&amp;feature=youtu.be\" target=\"_blank\" rel=\"noopener noreferrer\">video<\/a> from one of the project\u2019s partners ELEA explains this mechanism:<\/p>\n<\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"margin-left: auto;margin-right: auto;width:100%;\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"margin-left: auto;margin-right: auto;width:100%;\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"margin-left: auto;margin-right: auto;width:100%;\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-video fusion-youtube fusion-aligncenter\" style=\"max-width:600px;max-height:360px;
