where Cs is the concentration of non-removed extract from the soybean at equilibrium (in g oil/g of soybean). Values of C0 were determined experimentally, while values of C∞ were obtained by model fitting (MTKM).
The thermodynamic parameters of enthalpy change H◦ (kJ mol−1) and entropy changeS◦ (J mol−1 K−1) from the soybean oil extraction were calculated by a linear fit of the Van’t Hoff equation:
