Parameters identification associated with textured soy protein thermal diffusivity via high-order numerical methods

Abstract

Article InformationThe sterilization process of canned foods in retorts is widely used in the food industry for preservation purposes. Accurate temperature distribution during the process is crucial for determining optimal sterilization parameters. This study proposes estimating the thermal diffusivity as a function of temperature, which proves to be more reliable for heat transfer by diffusion compared to using a constant value. A high-precision finite volume method is employed to solve the governing differential equation, minimizing numerical errors in parameter estimation. The main result demonstrates that the utilization of temperaturedependent thermal diffusivity reduces the simulated temperature error compared to experimental data by nearly nine times, highlighting its fidelity to the actual heat transfer process.
