Abstract

We have developed an unusual plasma source that allows the generation of plasma exclusively within a sealed container or bag, from an entirely external electrode system. This device is unique in that it can be applied to standard sealed packaging and does not subject the package contents to any significant electric fields. This system can be used to modify the atmosphere inside the package by generating active species such as free radicals and ozone from the gas within it. This allows, for example, sterilisation or decontamination of the contents of a presealed container without the risks associated with handling ozone in open atmosphere. We present results showing the efficacy of this system in reducing the contamination of foodstuffs with pathogens such as Campylobacter and E.coli.
