Effect of Pulsed Electric Field (pef) on Escherichia Coli within the Liquid Whole Egg
نویسندگان
چکیده
The objective of the present study was to evaluate the efficiency of pulsed electric field (PEF) against Escherichia coli contaminating the liquid whole egg (LWE). The samples of LWE were inoculated with the test bacteria and subsequently treated for 30 μs by the different number of pulses (20-180) of PEF (32.89 kV x cm). Application of PEF resulted in statistically significant reduction of the test microorganisms, proportional to the number of pulses used. Depending on the studied strain, treatment with 150-160 PEF pulses was required to obtain the reduction of initial bacterial level by 4 log units. Considering the obtained results, PEF seems to be an effective technique, improving the microbiological status of LWE, and consequently its industrial application is highly advisable.

The aim of the work was determination of functional and rheological properties of liquid whole egg (LWE) after pulsed electric field (PEF) treatment. LWE was obtained from eggs of 27 weeks old layer hens Tetra SL. Parameters of PEF treatment were chosen according earlier experiment results where significant reduction of microflora was observed (32,89 kV/cm and 20, 60, 100 pulses). It was conclu...

Apple juice inoculated with Escherichia coli ATCC 23472 was processed continuously using either ultraviolet (UV), high-voltage pulsed electric field (PEF), or a combination of the PEF and UV treatment systems. Apple juice was pumped through either of the systems at 3 flow rates (8, 14, and 20 mL/min). E. coli was reduced by 3.46 log CFU/mL when exposed in a 50 cm length of UV treatment chamber ...
