CFD approach for modelling microbial inactivation during thermal processing of intact eggs.

Combined conductive and convective heat transfer during thermal pasteurisation of intact eggs was studied using a commercial Computational Fluid Dynamics (CFD) package. A kinetic inactivation model for Salmonella enteritidis was combined with the CFD model, enabling evaluation and assessment of egg pasteurisation processes. Simulated temperature profiles were found to be in good agreement with experimentally observed data. The obtained results offer a useful tool for assessment and optimisation of egg pasteurisation processes.
