چکیده
|
Moisture sorption isotherms of peppermint tea treated by thermal and biochemical process were determined at 30, 40 and 50°c using the static gravimetric method. gab model found to be the most suitable model for describing the sorption curves among three well-known tested equations. thermodynamic properties such as differential enthalpy and entropy of sorption were determined from moisture adsorption and desorption data, using the clausius-clapeyron equation. the experimental data showed that enthalpy-entropy compensation theory was applicable to the moisture sorption behaviour of peppermint tea.
