: Dense phase carbon dioxide is a non-thermal processing
alternative with many advantages for the pasteurization of juice. This chapter
discusses the validation, scale-up, and commercialization of the first dense
phase carbon dioxide processing system in the United States. Process
validation and shelf life studies showed that dense phase carbon dioxide
processing is capable of maintaining the freshly squeezed quality of orange
juice while meeting the 5-log reduction on pertinent pathogens as mandated
by the Food and Drug Administration Juice Hazard Analysis Critical Control
Point Regulation. Results of the pilot model, the prototypes, and the
commercial system demonstrated that the dense phase carbon dioxide system
is scalable in terms of size and performance.
