EFFECTS of ELECTRICITY ON MICROORGANISMS: A REVIEW

Although the idea of electrical treatment of foods for microbial control is not new, the data available on nonthermal effects of electricity are limited and inconclusive. an understanding of such effects would be useful in developing new methods for microbial inactivation. the present review discusses a number of different methods of electrical treatment and their nonthermal effects on microorganisms. Subjects discussed include electric pasteurization of milk, electrohydraulic shock, electroporation, and electroconductive heating. Information relating to mechanisms contributing to microbial death is summarized and discussed.
