heal.abstract	The prediction of infinite dilution volatilities (Henry's law constants) of aroma compounds is examined. At 25 degreesC, the Bond Contribution model is recommended. At other temperatures where the Bond Contribution model cannot be used, the Kow-UNIFAC group contribution model, coupled with either experimental or predicted by the Antoine-Grain model vapor pressure values, provides estimates only of the volatilities with errors in the range of 20% to 40%. Finally, the effect of a cosolvent (ethanol) on the infinite dilution volatilities of some aroma compounds is examined.	en
