Fresh pork Atmospheric pressure plasma 2.45 GHz, 1.2 kW; process gas air pH decreased, CIE a* increased and CIE b* decreased upon plasma treatment. Fröhling et al. (2012)

Beef jerky Plasma beam system N2 or air, 20 kHz, 300 W, brine (sodium nitrite) solution Comparable texture and lipid oxidation values in samples cured in plasma-activated brine as opposed to standard curing. Significantly higher CIE a* in samples cured in plasma-activated brine. Inguglia et al. (2020)
Beef jerky Flexible thin-layer plasma system Linear electron-beam RF accelerator (2.5 MeV, beam power 40 kW) Plasma treatment decreased the CIE L* and increased the CIE a* and ΔE values. Yong et al. (2017a)
Pork jerky DBD plasma Air, 4 kHz, 3.8 kV, 40 min Jerky made with plasma treatment for 40 min had similar color values, nitrosoheme pigment, lipid oxidation, and texture properties as opposed to jerky made with sodium nitrite (100 ppm). Yong et al. (2019)
Bacon Atmospheric pressure plasma He/He+O2; 125 W; 14 MHz, 90 s Plasma treatment increased the TBARS values in bacon after a 7-d storage CIE L* of the bacon surface was increased. Kim et al. (2011)
Chicken patties DBD plasma 65% O2+30% CO2, 70 kV, 1% rosemary, 180 s Plasma treatment increased lipid oxidation. However, MDA level decreased upon the addition of rosemary extract to the product. Gao et al. (2019)
Canned ground ham DBD plasma Air, 600 W, 25 kHz, 30 min Plasma treatment had no effect on lipid oxidation. Lee et al. (2018)
Ground ham Atmospheric non-thermal plasma (ANP) Air, 1.5 kW, 60 kHz, 30 min Temperature and residual nitrite levels increased when cured by remote infusion of ANP (RANP) compared to sodium nitrite.
