摘要
The effect of pulsed electric field (PEF) treatment on the inactivation of microorganisms and relevant functional properties of porcine blood was investigated. Whole blood inoculated with Escherichia coli, Staphylococcus xylosus and Pseudomonas fragi was processed by a continuous pilot-plant PEP system using a 14 kV/cm electric field strength and specific energy input was varied in the range of 58 - 147 kJ/kg (treatment times between 78 - 233 mu s).
