Abstract: In predictive microbiology, the Ratkowsky square root model is known as a model that describes the influence of suboptimal growth temperatures on the maximum specific growth rate of microorganisms. By integrating the square root model into Baranyi's model, this one becomes a secondary model, dependent on time and temperature. D- and c- optimal experimental designs are provided for the Baranyi model with two controllable variables and considering different perspectives. These designs are compared by means of efficiency with those provided in the literature.
