- Abstract
- Inactivation of Escherichia coli was attempted using dielectric barrier discharge plasma (DBDP) generated at different currents and electrode-gaps in order to explore its potential as a nonthermal sterilization technology for food products. DBDP showed a potent inactivation power against Escherichia coli especially in initial treatment stage up to 4 min although the effect retarded afterward, indicating that the inactivation pattern deviated from first order reaction kinetics. Instead, the inactivation pattern fitted well to Singh-Heldman model showing shape factors of 0.545-0.783 and D'-values of 0.565-3.268 min at different currents and electrode-gaps with a fixed sample treatment method. The greatest inactivation power of DBDP showing the smallest D'-value was observed at 1.25 A current and 2.65 mm electrode-gap. The inactivation effect was improved by an uniaxial moving samples during the treatment. DBDP treatment with a biaxial movement of the samples boosted the inactivation power furthermore.
