The sorption isotherms give information about the interaction of biopolymers with water vapor. These are extremely important in modeling drying processes and prediction humidity changes during product storage. An analytical expression for vapor agricultural products was developed using statistical physics formalism. model further used to fit interpret desorption Tunisian olive leaves some food products. In this model, five parameters relation process intervene, such as number molecules per...
