8F.1 Introduction


Although there are many studies in the literature that have focused on the identifica-


tion and quantification of wine aroma compounds, to understand fully wine aroma


perception it is necessary to incorporate the study of the interactions between aroma


components and non-volatile wine matrixmacro-components. This phenomenon
influences aroma volatility and solubility, and thus its release from wine. Aroma


release ultimately influences aroma perception. Although some research has been


devoted to the study of interactions of aroma compounds and non-volatile com-


ponents of wine, the diversity and significant of these interactions have not been


thoroughly considered. This chapter is devoted to a discussion of this topic.


8F.1.1 Partition Coefficient


Aroma perception of a food, e.g. wine, is strongly influenced by the way indigenous


aroma molecules distribute between the gas and liquid phases. This distribution
