Sažetak
Sage (Salvia officinalis L.) and winter savory (Satureja montana L.) are melliferous plants which are common for Mediterranean region of Croatia, so as for other parts of southern Europe (Spain, Italy, France). Both plants are used as spice/flavouring plants or medicinal herb. Also, they are honey bearing plants and these two honey types are appreciated and run up high market price. Sage and winter savory honey have been characterized in the last years through physicochemical parameters, pollen spectra and sensory analyses but due to increased incidence of honey adulteration new parameters for providing honey authenticity are needed. In the last thirty years stable carbon isotope ratio (δ13C) method is used for detection of honey adulteration with sugar cane or corn syrups. Recently, researches have been focused on application of stable isotopes determination for honey botanical and geographical origin assessment. The data about stable isotopes in honey are scarce compared to other well-known parameters, and sage and winter savory honey are not characterized from this aspect yet. This paper presents the results of stable carbon (δ13C) and nitrogen (δ15N)isotope ratio in sage and winter savory honey from the Republic of Croatia and considers the possibility of using this parameter in assessment of honey authenticity. Average δ13Choney and δ13Cprotein values for winter savory honey were -27.93‰ and -26.65‰, while for sage honey they were -26.38‰ and -26.57‰, respectively. Both honey types had low average δ15N values (-0.10‰ and 0.95‰) which are among the lowest values in comparison to literature for other honey types.
