The microbial and enzyme activity in different points within cheese and quality of final product are determined by local concentrations of salt and moisture in aqueous phase. To predict the evolution of moisture content in different layers of the Iranian white cheese during brining, constant and variable moisture diffusion coefficients were determined using experimental moisture time–dependent concentration-distance profiles. These experimental profiles for Iranian white cheese were obtained in rectangular samples, ensuring semi-infinite unidirectional mass transfer within saturated solution of sodium chloride at different temperatures (6, 14, 19, 24 °C) and brining times (6, 24, 48 h). Results showed that moisture diffusivity increases with increasing temperature and moisture content in cheese aqueous phase. The variation of the moisture effective diffusivity as a function of temperature was represented by the Arrhenius’s relation. Finally, the relation of diffusivity with moisture content and temperature was developed. The predicted diffusivity values using the developed model showed a good agreement with the experimental values by using Boltzman variable method.
