During processing of complex multiphase systems several processes occur on different time and length scales simultaneously and influencing each other. To establish the main relevant driving process, time-scale analysis is an important tool in physics. This work outlines the physical and chemical kinetics occurring during cereal based foam processing and contributes to enlighten the impact of different characteristic times. Such analysis becomes beneficial if detailed micro-scale description of the whole process is required which may be used for process optimization. With regard to the latter, an important tool is numerical modeling where a sophisticated knowledge of the processes, time and length scales is required to produce realistic results. The time scale estimation shows the impact of each process on the whole macro scale behavior of the system and gives a critical review of previous physical and mathematical models and the related simulation approaches.     «
