Studies to date on plasma have shown its capability to injure and inactivate pathogenic bacteria on inert food contact
surfaces, solid foods and in liquids [59-63]. These include decontamination of fruits [62], vegetables [64] and milk [63].
Recent investigations on the bacteriocidal effects include the evaluation of the inactivation of food-borne pathogens
seeded onto thin films of agar, treated with NTP [65], and sprayed onto the surface of heat sensitive polyethylene
terephthalate (PET) foils. A 5 log reduction in E. coli adsorbed on the surface of almonds, was observed using a DB
system [61-62]. Other studies have focused on the inactivation efficiency of cold plasma with respect to contaminated
of pericarps of mangos, melons [66], bell peppers [67], almonds [62], eggs [68], Cheese and meat products [36], and
milk [63]. Although these are very limited preliminary studies, the potential of this technology in food processing is
being recognised.
