Moisture sorption isotherms and thermodynamic properties
Moisture sorption isotherms of Mentha pulegium and Mentha rotundifolia were
determined at 30, 40 and 50 °C using the static gravimetric method. GAB, modified Halsey and
Peleg models were fitted to the experimental data and the agreement between experimental and
predicted values was satisfactory. Calculation of the thermodynamic properties was further used to
provide an understanding of the properties of water and energy requirements associated with the
sorption behaviour. Isosteric heats of sorption were calculated through direct use of moisture
isotherms by applying the Clausius-Clapeyron equation. The differential enthalpy and entropy
decreased with increasing moisture content and were adequately characterized by a power law
equation. A plot of differential heat versus entropy satisfied the enthalpy-entropy compensation
theory.
