抜粋

The sorption equation of flavors with packaging film to extend for various flavors and polymers was derived by improving the proposed δc concept. On the basis of the findings that the sorptions depend on both the δc values between film and flavors with similar chemical potential and their molar heat of vaporization (ΔHvap), the following thermodynamic sorption equation was derived: S = So exp γ[Vvv2c2)/RT]. For aqueous phase the plots of In S vs the term of the equation gave an adequate but insufficient relationship (r = 0.802), resulting from the influence of any interaction force from solution on the magnitudes of physical adsorption and condensation of flavors on film surface. On the other hand, for vapor phase the same plots gave a quite sufficient correlation (r = 0.967). Therefore, in the prediction of the sorption behaviors for vapor phase the derived sorption equation may be more useful and effective.
