Discrimination of Korean beef from beef of other origin by stable isotope measurements

Worldwide stable carbon and nitrogen isotopes of Big Mac® patties: An example of a truly “glocal” food

“…Our results are consistent with other studies analysing beef samples from several parts of the world, which found high d 13 C values of Brazilian beef samples (Heaton et al, 2008;Nardoto et al, 2006;Schmidt et al, 2005). Previously published studies also found high d 13 C values (À14.3‰ to À9.5‰) for US beef samples (Bong et al, 2010;Heaton et al, 2008;Horacek & Min, 2010;Nakashita et al, 2008;Schmidt et al, 2005); and for patties from US fast-food chains (Chesson et al, 2008). The lower d 13 C values observed in Big Mac Ò patties from European countries were also observed in beef sampled from that continent (Heaton et al, 2008;Schmidt et al, 2005).…”

“…The lower d 13 C values observed in Big Mac Ò patties from European countries were also observed in beef sampled from that continent (Heaton et al, 2008;Schmidt et al, 2005). The large variance we observed in the d 13 C values of Big Mac Ò patties from Australia (Table 1) was also observed in beef samples from this country (Bong et al, 2010;Heaton et al, 2008;Horacek & Min, 2010;Nakashita et al, 2008).…”

H, C, N and O stable isotope characteristics of alpine forage, milk and cheese

“…The breed of the cows was Italian Red Pied and Tarantaise in AV and Brown Swiss in MDS. Studies of the literature on beef, lamb and pig (as examples: Camin et al, 2007;Harrison et al, 2011;Horacek & Min, 2010;Knobbe et al, 2006;Molkentin, 2009;Molkentin & Giesemann, 2007Tuross, Warinner, Kirsanow, & Kester, 2008) did not highlight a great influence of breed on the variability of stable isotope ratios of bioelements. At the AV site (details on AV vegetation are reported in Falchero et al, 2010) they fed on an oligotrophic type mainly made up of Trifolium alpinum, Nardus stricta, and Carex sempervirens (AV-T), and a mesophilous type with Festuca gr.…”

Light-Element Isotopes (H, C, N, and O) as Tracers of Human Diet: A Case Study on Fast Food Meals

“…Using the predicted tap water oxygen isotope ratio (d 18 O we ) of the location (Bowen et al 2007 Tracing the geographical origin of beef has recently been recognized as a food-safety concern in Europe and Asia. Preliminary data suggest the stable isotope analysis of beef may be useful to answer questions of region-of-origin (Nakashita et al 2008;Bong et al 2010;Horacek and Min 2010). A recent survey of beef raised in Japan published by Nakashita et al (2008) …”
