Sažetak
Honey aroma is very complex, involving many tens of volatile compounds [1]. The analysis of volatile fraction of unifloral honey provides useful information for the botanical and geographical origin determination. Croatian Lavandin honey is generated mostly from the nectar of Lavandula hybrida Reverchon. Volatile compounds from three samples of unifloral Lavandin honey (pollen content > 20%) were investigated. The volatiles were isolated by ultrasonic solvent extraction (USE) and hydrodistillation (HD) and analysed by gas chromatography - mass spectrometry (GC-MS) on HP-20M column. The obtained results vary greatly upon the isolation method employed. USE is more suitable for the isolation of low and high molecular weight compounds providing potential biomarkers for unifloral honey origin determination [2, 3]. Aliphatic and aromatic hydrocarbons, terpenes, phenylpropane derivatives and carboxylic acids were identified. The content of ubiquitous benzoic acid and phenylacetic acid was low that could be important for comparison with other unifloral honeys. Major qualitative differences were observed in comparison with the volatile profiles of Lavandula stoechas, Lavandula angustifolia and Lavandula angustifolia x latifolia honeys from Portugal and France [5]. Coumarin was also identified and it can be used as an indicator of honey freshness [5]. HD has main drawbacks because of the drastic isolation conditions (boiling water) that lead to the formation of artefacts (Strecker degradation and Maillard reactions). The isolated honey volatiles were compared with three samples of Lavandin essential oil obtained by steam distillation. Common monoterpene compounds among the honey volatiles and the essential oil were 1, 8-cineole, cis- and trans-linalool oxide, camphor, linalool, terpinen-4-ol, borneol and geranyl acetate.
