Mathematical modelling of the sorption isotherms of quince

ABSTRACT
The moisture adsorption isotherms of quince were determined at four temperatures 15°C, 30°C, 45°C and 60°C over a range of water activity from 0.110 to 0.920 using the standard static gravimetric method. The experimental data were fitted with generated three-parameter sorption isotherm models on Mitrevski et al., and the referent Anderson model known in the scientific and engineering literature as Guggenheim-Anderson-de Boer (GAB) model. In order to find which models give the best results, large number of numerical experiments was performed. After that, several statistical criteria for estimation and selection of the best sorption isotherm model was used. The performed statistical analysis shows that the generated three-parameter model M11 gave the best fit to the sorption data of quince than the referent three parameter Anderson model.
