Differentiation of Turkish Rakies through Headspace Solid‐Phase Microextraction and Gas Chromatography‐Mass Spectrometry Analysis

Composition of flavour compounds from several commercial raki samples was determined through headspace solid‐phase microextraction (HS‐SPME) and gas chromatography coupled to mass spectrometry (GC‐MS). The extraction of volatile compounds was performed using a 75 μm CAR/PDMS fibre. Forty three volatile compounds were identified. The major compounds were trans‐anethole (86.47–94.19%), valencene (1.15–6.77%), estragole (2.66–5.46%), and cis‐anethole (0.72–2.33%). Principal component analysis (PCA) enabled the differentiation of the raki samples thanks to compounds arising mainly from aniseed.
