A solid‐phase microextraction (SPME)‐based method for the GC‐MS analysis of volatiles in dehydrated carrot root samples has been developed and the effect of the most important factors (fibre coating, extraction temperature, equilibrium time and extraction time) on the fractionation of different volatiles has been studied. GC‐MS chromatograms showed terpenoids relevant to carrot aroma such as α‐pinene, sabinene, β‐myrcene, limonene, γ‐terpinene, terpinolene, trans ‐caryophyllene and β‐bisabolene, and several furan derivatives whose origin is discussed in this paper. As an example of application, this methodology has been used for the characterization of volatile composition of industrially dehydrated carrots. SPME followed by GC‐MS is shown as an affordable, fast and solvent‐free technique which can be performed with low sample amounts and be easily implemented at an industry for quality control purposes.
