Table 4. Effect of PEF on the microbial inactivation of different muscles

Meat materials PEF condition Target microbes Findings References
Chicken breast fillets 0.2 ms, 4.67, and 7 kV/cmContinuous treatment during storage period Total mesophilic aero bacteria (TMAB), total coliform bacteria (TCB)Listeria monocytogenes, Pseudomonas aeruginosa The limit for TMAB counts was exceed in PEF-treated samples 2 days later than the control samples.The TCB counts were reduced with 2 Log CFU/g in PEF-treated samples. The counts of L. monocytogenes and P. aeruginosa were maintained in 7 kV/cm PEF treated samples during the storage periods. Aşık-Canbaz et al. (2022)
Beef jerky 20 μs, 20 Hz, 0.52 kV/cm, 606 pulses Total plate count, coliform yeast and mold The microbial contamination by PEF treatment was not observed. Bhat et al. (2020)
Deep and superficial pectoral (beef) 20 μs, 50 Hz, 0.7 and 1.5 kV/cm, 1,030 to 6,400 pulses Lactic acid bacteriaTotal aerobic bacteria The microbial inactivation effect was not observed after PEF pretreatment. Alahakoon et al. (2019)
Semitendinosus (beef) 20 μs, 50 Hz, 1.4 kV/cm, 1,032 pulses Total aerobic bacteria The growth of aerobic bacteria in fresh meat was not different between PEF-treated and untreated meat over the course of 7 days.The growth of aerobic bacteria in frozen-thawed meat increased 2 Log CFU/g in PEF treated meat at 7 days. Faridnia et al. (2015)
Longissimus thoracis et lumborum (pork) 20 μs, 100 and 200 Hz, 1.2 and 2.3 kV/cm, 150 and 300 pulses Total viable count (TVC) The TVC was not affected by PEF treatment. McDonnell et al. (2014)
Minced beef meat 28 to 2,800 MHz, 300 V/m, treatment time: 15 mins, pulse width not described Yersinia enterocolitica The Y. enterocolitica inoculated in the meat was reduced under 1 Log CFU/g. Stachelska et al. (2012)
Chicken breast 10 μs, 5 Hz, 3.75 and 15 kV/cm, treatment time: 10 to 30 sec Campylobacter jejuni Escherichia coli, Salmonella enteridis, Enterobacteriaceae, total viable counts The microbes were unaffected by PEF treatment. Haughton et al. (2012)
