The volatile odorant fraction of aromatic caramel was investigated using GC/O and GC/MS analyses. Forty nine aroma compounds were identified, some of them being reported for the first time in caramel. Sensory properties were also evaluated by establishment of descriptive profiles. The relationship between the sensory properties and the GC/O data was modeled by Partial Least Square regression (PLS-R). Heterocyclic compounds, carbocyclic compounds and carboxylic acids appeared to be the main contributors to the caramel odorant properties.
