Tracing the geographic origin of poultry meat and dried beef with oxygen and strontium isotope ratios

Abstract

Two promising isotope ratios, the d18 O of the water fraction, as extracted by azeotropic distillation, and the 87 Sr/ 86 Sr of the ash fraction were tested for their applicability to determine the geographic origin. In two sampling phases, in total 78 fresh poultry breast meat and 72 dried beef samples, independent from each other and originating from different countries, were analysed.

Tissue turnover in ovine muscles and lipids as recorded by multiple (H, C, O, S) stable isotope ratios

“…However, analytical tools are needed to enable confirmation of country of origin of animal products and to verify the authenticity of foods. The potential of stable isotope ratio analysis (SIRA) in this regard has been demonstrated (Camin et al, 2007;Franke et al, 2008;Heaton, Kelly, Hoogewerff, & Woolfe, 2008;Schmidt et al, 2005).…”

“…While not of zip code precision, stable isotope analyses can provide information about bands or zones consistent with region-of-origin. Similarly, animals record the stable isotope ratio of consumed water in their tissues (Boner & Förstel, 2004;Heaton, Kelly, Hoogewerff, & Woolfe, 2008) and the stable isotope analysis of meats can be used to answer questions of food origin (Franke et al, 2008).…”

Combination of multi-element and stable isotope analysis improved the traceability of chicken from four provinces of China

“…To date, most of the studies using the element analysis technique focused on the geographic traceability of beef, and little attention has been paid to that of poultry. Franke et al (2007) and Franke, Hadorn, et al (2008) determined the multiple trace element contents of poultry meat from different countries to identify their geographic origins, and from the results we see that the combination of both oxygen isotope and trace elements did not improve the classification of origin (Franke et al, 2007;Franke, Koslitz, et al, 2008).…”
