In recent years， with the rapid development of food industry， it is a big challenge to achieve high-quality food process， which is required for food safety， sensory and nutrition as well as for the reduction of energy consumption. Due to the illustration of food processing and the improvement of computer performance gradually， many phenomenon during processing such as heat and mass transfer， chemical reactions and local effects， could be described by mathematical modelling and simulation. It is the basis of the precise control and energy saving for food engineering. Therefore， we summarized the progress of food systems and processes relating to modeling and simulation. This review aimed at promoting the application and development of digital technology in food processing.
