Static headspace measurements were performed using Atmospheric Pressure Chemical Ionisation- Mass Spectrometer (APCI-MS) to determine volatile partitioning from a series of milk-based emulsions. The 20 aroma compounds studied exhibited a broad range of hydrophobicity/ hydrophilicity in model emulsions. Experimental method was done using 6 samples with different lipid contents (0.002-0.102 g/mL). The results showed that there were three groups of volatile compounds due to their lipophilicities; the least, intermediate and most lipo-philic volatile compounds. Overall, the release of lipophilic molecules was so dependent of the fat content of the matrix which opposed to the release of the very hydrophilic compounds.
