title: Influence of composition (CO2 and sugar) on aroma release and perception of mint-flavored carbonated beverages.
abstract: The aim of the present work was to identify and quantify physical mechanisms responsible for in-nose aroma release during the consumption of mint-flavored carbonated beverages in order to better understand how they are perceived. The effect of two composition factors (sugar and CO(2)) was investigated on both the sensory and physicochemical properties of drinks by studying in vitro and in vivo aroma release. Sensory results revealed that the presence of CO(2) increased aroma perception regardless of the sugar content. In agreement with volatility parameters, in vivo measurements showed that carbonated drinks released a greater quantity of aroma compounds in the nose space than non-carbonated ones. CO(2) seemed thus to induce large modifications of the physicochemical mechanisms responsible for the aroma release and flavor perception of soft drinks. Moreover, sugar content seemed to have an impact (increase) on aroma perception only in the case of non-carbonated beverages. Sensory interactions were thus observed, in particular, between sweet and aroma perceptions. For carbonated beverages, sugar content had an impact only on aroma release, but not on their perception.
