Characterisation of the volatile odorant fraction of aromatic caramel using heart cutting two-dimensional gas chromatography.

Poster (1 page); National audience; Odour is one of the main factors contributing to the consumer acceptability of food products. Characterization of odorant compounds thus represents an important challenge for the food industry. Caramel is the resulting product of controlled heat treatment of sugars. Its volatile fraction includes a large number of oxygenated heterocycles as furans and furanones. Due to similar properties, these compounds exhibit similar interactions with the column stationary phase. Consequently, the one-dimensional Gas Chromatography (GC) profile of the volatile fraction of caramel shows numerous co-elutions. The aim of this study was to optimize a two-dimensional chroma…
