Flavour Science

Two different techniques for obtaining extracts representing the most relevant aroma chemicals from grilled lamb have been developed and applied to the elucidation of the gas chromatographic-olfactometric (GC-O) profiles of grilled lamb from fresh or frozen samples. The first one attempted to collect the aroma released during grilling; the second one, the aroma released during eating. The GC-O work was complemented with a thorough isolation and identification study comprising liquid chromatography and dual gas chromatography with simultaneous MS and olfactometric (GC-GC-O-MS) detection.
