Ethyl heptanoate (EH), a food aroma compound, was added to water and allowed to come to equilibrium with a known volume of air and results showed that its partition coefficient, [EHair]/[EHwater] is equal to 1.8 x 10-2. In the same experiment with oil in place of water, its partition coefficient, [EHair]/[EHoil] is found to be lower at 6.0 x 10-6. Account for the difference between the two values.
