Technical Abstract: In the quest to provide consumers with safe, nutritious, delicious, and affordable liquid foods, many nonthermal technologies have been researched. Radio frequency electric fields processing is related to pulsed electric fields processing and looks promising, yet has not been commercialized. Ultraviolet light processing and dense-phase carbon dioxide processing have been commercialized, but only to a limited extent. All three technologies are capable of nonthermally reducing the population of bacteria by 5 log. An overview of each technology will be presented including applications, microbial inactivation kinetics, inactivation mechanisms, regulatory issues, and costs. Finally, a comparison of the three technologies will be offered along with their future prospects.
