Isotope Investigation of Retail Beef

Iso-Analytical has been working for a number of years in collaboration with Dr. Olaf Schmidt and colleagues from University College Dublin in isotopic investigation of beef with a view to the authentication of Irish beef. The first publication resulting from this work: Inferring the origin and dietary history of beef from C, N and S stable isotope ratio analysis. Food Chemistry (2005) 91:545-549 compared beef reared in the USA, Brazil, Europe and Ireland. A second publication on the seasonal variation of ¹³C, ¹⁵N and ³⁴S in organic and conventional Irish beef is currently in press. In August, Bahar et al. gave a poster presentation on the rate of dietary carbon and nitrogen incorporation into bovine muscle at the 58th Annual meeting of the European Association for Animal Production. We have made a copy of the poster available for download in Adobe Acrobat (PDF) format here (1.9 MB).

Example Laboratory Reports

We have made a selection of example laboratory reports available for download in Adobe Acrobat (PDF) format from our website. Currently you will find example reports for the following services available:

¹³C-Urea Breath testing for detection of Helicobacter pylori infection
¹³C and ¹⁵N (dual isotope) analysis of Animal Tissue samples for ecological profiling
¹³C and ¹⁵N (dual isotope) analysis of Bone Collagen samples for dietary reconstruction
Deuterium (²H) analysis of core waters for Deuterium Tracing of core invasion
Doubly Labelled Water (DLW - ²H and ¹⁸O) analysis for measurement of Total Body Water composition
Fruit Juice carbon-13 testing for detection of undeclared addition of corn syrup
Honey carbon-13 testing (SCIRA & ISCIRA) for detection of economic adulteration

These example reports highlight our quality control procedures and the strong emphasis we place on the presentation of results.
