In the pasta production process, drying is an energy-intensive stage which affects many of the final
product properties. However, the drying process for pasta is only understood on an empirical basis. The availability
of a reliable mathematical model for drying can provide a better understanding of how the different parameters affect
the food quality of dried pasta. Models can also allow optimization of the drying process design and/or operation
and associated cost reductions. Drying includes simultaneous heat and mass transfer phenomena, and development of
a model requires a complex system of coupled nonlinear partial differential equations. Furthermore, models usually
include several parameters with unknown values which are not easy to estimate, this is especially true for food materials
such as pasta. This work is a review of the different aspects of mathematical modeling of pasta drying, methods and
correlations for the prediction of model parameters, as well as recent trends in numerical solution. The application
of computational fluid dynamics approaches is discussed. This paper includes a discussion on prediction of the pasta
quality indices obtained from the numerical modeling
