Inactivation of Escherichia coli, Listeria innocua and Saccharomyces cerevisiae in relation to membrane permeabilization and subsequent leakage of intracellular compounds due to pulsed electric field processing

Amplitude Modulated Waves as a Promising Tool for Food Preservation

“…Such reduction might be due to breakdown of cell membrane (Calderon-Miranda et al, 1999;Schoenbach et al, 2000;Dunne, 2000;Oshima and Sato, 2004;Aronsson et al, 2005).…”

“…Electromagnetic waves are nonionizing radiation proved to affect some physiological activities of living organisms (Piskorz-Binczycka et al, 2003;Maxim et al, 2004;Aronsson et al, 2005). Such effects are found to be time, frequency and intensity dependent (Grahl and Markel, 1996;MacGregor et al, 2000;Bamidele et al, 2012).…”

Comparative analyses of prediction models for inactivation of Escherichia coli in carrot juice by means of pulsed electric fields

“…For the instances where the survival curves may not follow the loglinear relationship, alternative mathematical models are desirable to describe the survival curves (Rivas et al 2006). Immense studies have been carried out in buffered media (Aronsson et al 2005;Toepfl et al 2007) and actual food (Saldaña et al 2011) to canvass the inactivation kinetics of pathogen and yeast. Various models based on the empirical and phenomenological considerations have been proposed (Peleg and Penchina 2000;Van Boekel 2002).…”

Effect of pulsed electric fields upon accumulation of magnesium in Saccharomyces cerevisiae

“…The electric field can affect the cell membranes [21], which can irreversibly be damaged [22][23][24], influences the transport of ions [25] and structure of enzymes [26]. In a cell subjected to PEF-induced transmembrane tension facilitates the formation of pores in the membrane and leads to an increase in its permeability [27][28][29][30][31]. Electroporation temporarily eliminates integrity of the plasmatic membrane, i.e., produces small pores that close back with a time [31][32][33].…”
