Review of modelling and simulation of high pressure treatment of materials of biological origin

The present paper gives an overview of approaches which have been reported in literature for modelling and simulating the treatment of materials of biological origin such as food with ultra high pressures (up to 1000 MPa). Of the different approaches, chiefly balancing methods are considered here for convenience. Within this context a description of pure time-dependent processes as well as fields of molecular and cellular systems driven by unavoidable thermofluiddynamical transport are given. This provides the basis required for tracing the “complete treatment history” that determines in turn the quality and safety of any product of biological origin. For this purpose, general model equations are presented and simplified to the extent necessary for matching the framework of the different contributions.
