The aim of this work is to give a deeper understanding of the impact of the salivary composition on aroma release, by two approaches, an in vitro and an in vivo approach. The impact of salivary proteins on the release of 10 aroma compounds (5 esters and 5 ketones, varying in their hydrophobic chain length) was first investigated by in vitro model systems composed of artificial and human saliva. Artificial salivas were composed of the main salivary proteins, mucins and alpha amylase, alone and in mixture.The amount of aroma released in the vapor phase at equilibrium was analyzed by Static Headspace Gas Chromatography analysis. Air/system partition coefficients have been calculated. This in vitro approach allowed us to demonstrate the ability...
