Aroma release in fat free dairy gels added or not added with pectin
Résumé
The replacement of fat by thickeners in fat free yogurts leads to an important modification of aroma compounds partitioning, with an impact on aroma perception (Guichard, 2002). Investigation of retention/release equilibriums allows a good understanding of aroma compounds behaviour depending on food composition. The aim of this work is to study the influence of matrix composition on aroma release.
