Modified forms of the Guggenheim-Anderson-de Boer model (mGAB), Halsey model (mHAL), Henderson model (mHEN) and Oswin model (mOSW) with temperature term were used to describe the sorption isotherm experimental data of pine nuts at different temperatures. Goodness-of-fit indices were examined to evaluate the moisture sorption models, and the mGAB model showed the best performance at individual temperatures. Furthermore, the mHEN and mOSW models were able to differentiate the temperature effect effectively with the lowest AICc values in one-step modeling.
Modified forms of the Guggenheim-Anderson-de Boer model (mGAB), Halsey model (mHAL), Henderson model (mHEN) and Oswin model (mOSW) that incorporate a temperature term were selected and used to describe sorption isotherm experimental data of pine nuts that were obtained using the static gravimetric method at 15 degrees C, 25 degrees C and 40 degrees C. A series of goodness-of-fit indices with random and normal residual distributions, the statistical significance and the precision of the parameter estimates were examined to adequately evaluate the pine nut moisture sorption models. The mGAB model best described the sorption isotherms at individual temperatures. Moreover, with the lowest AICc values, the mHEN and mOSW models best differentiated the temperature effect in one-step modelling.
