The artificial throat: a new device to simulate swallowing and in vivo aroma release in the throat. The effect of emulsion properties on release in relation to sensory intensity

Abstract

The effects of oil content and droplet size distributions of dilute oil-in-water emulsions on release of 4 esters with different hydrophobicities were studied under in vivo , staticheadspace, and artificial throat conditions. The effect of oil content on orthonasal and retronasal perceived intensity of ethyl hexanoate was studied using a sensory panel. The results indicate that the effect of droplet size distribution on aroma release strongly depends on the hydrophobicity of the aroma compound, the emulsion characteristics and the dynamics of the measurement. The lowest oil content that had an effect on aroma release was determined for all systems.
