The application of plasma-activated water combined with mild heat for the decontamination of Bacillus cereus spores in rice (Oryza sativa L. ssp. japonica)

This study applied the combination of plasma-activated water (PAW) and mild heat (40 and 55℃) for the decontamination of Bacillus cereus spores in rice (Oryza sativa L. ssp. japonica). In this study, PAW combined with 40 and 55℃ (PAW-40 and PAW-55) achieved 1.54 and 2.12 log10 CFU/g reduction of B. cereus spores in rice after 60 min exposure, which was significantly higher than the inactivation level (0.72 log10 CFU/g) induced by PAW treatment...
