HPP between 400 and 600 MPa from 1 to 10 min reduces several log reduction of spoilage organisms and pathogens such as E. coli O157:H7, Salmonella, Listeria, and Cryptosporidium. Some of the advantages of HPP for processing fresh juices include development of premium healthier juices with a higher level of functionality, avoid postcontamination and increase safety, expand markets, and protect the brand. Processors use HPP in their HACCP program to achieve the US FDA requirement of a 5-log reduction in pathogens in fresh juices.

In particular, the temperature increase with pressure was not linear and, therefore, the relative increase with respect to water depended on the pressure range selected as well as the initial temperature. Since in typical industrial process 5% of HP vessel is filled with packaging, compression heating behavior of packaging materials may affect heat transfer by forming insulation layer surrounding food and consequently temperature distribution within HP vessel. 1 Flexibility A packaging material needs to be flexible enough to withstand compression forces so that it can avoid irreversible deformations and maintain its physical integrity.
