PL

Pulsacyjne pola elektryczne (PEF) są jedną z niekonwencjonalnych metod utrwalania zazwyczaj płynnych produktów spożywczych, takich jak soki, mleko czy masa jajowa. Głównym czynnikiem wpływającym na inaktywację drobnoustrojów jest oddziaływanie polem elektrycznym, o wartości natężenia 10-80 kV/cm, czego skutkiem jest elektroporacja błony komórkowej drobnoustrojów, prowadząca do śmierci komórki i zwiększenia trwałości produktu spożywczego. Metoda PEF jest szczególnie skuteczna razem z innymi metodami w ramach” teorii płotkowej”.

EN

Pulsed Electric Fields (PEF) are one of the unconventional preservation method of mainly liquid food products like juices, milk or whole eggs. The main inactivation factor of microorganisms is treatment of PEF in range of 10-80 kV/cm what results in electroporation of microorganism’s cell and its death, what leads to longer “shell life” of food products. PEF method is especially useful with another methods in the framework of so called “hurdle theory”.
