Feed additives: authenticity assessment using multicomponent-/multielement-isotope ratio mass spectrometry
Markus Greule, Clarissa Hänsel, Ulrike Bauermann and Armin Mosandl
Since the ban on growth-promoting antibiotics throughout the EU essential oils are used increasingly as feed additives. In order to ensure a reliable authenticity assessment of those oils appropriate methods were developed. 2H/1H-, 13C/12C- and 18O/16O isotope ratio mass spectrometric analysis of carvacrol from origanum and savory oil, thymol from thyme oil and trans-anethole from fennel oil in combination with IRMS-analysis of minor components and diVerential analysis is reported.
