“…The δ 13 C value in meat has been found to be closely related to the feeds composition, especially with the composition of C 3 and C 4 plant material (Bahar et al, 2005;Moreno-Rojas et al, 2008). In the present study, all δ 13 C values of the collected chicken samples ranged from −17.5‰ to −15.7‰, suggesting that the main component of feed was maize, a C 4 plant (Knobbe et al, 2006;Yanagi et al, 2012). The δ 13 C values of JX chicken samples were lower than those of samples from other locations due to the higher content of rice in the feeds of JX chicken, since these samples were obtained from JX province, one of the largest production locations of rice in China.…”

“…The crops used for the feeds are grown by applying chemical fertilizer, resulting in lower δ 15 N values from −3‰ to 3‰ in the plants that will be delivered to the animals by assimilation (Bahar et al, 2008;Kelly, Heaton, & Hoogewerff, 2005). In another aspect, the feeds containing pea and soybean utilize atmospheric nitrogen directly, leading to less positive values of δ 15 N (Heaton et al, 2008;Yanagi et al, 2012;Zhao et al, 2013). Both reasons mentioned above are responsible for the lowest value of δ 15 N appearing in JX chicken samples.…”

The establishment of appropriate analytical methods to authenticate the geographic origin of poultry meat independent of paper record becomes especially important nowadays. In this study, data were analyzed in terms of both the contents of two stable isotopes (C and N) and 12 mineral elements of chicken samples from four provinces to trace their geographical origin. The results showed that classification of chicken was improved by combining both types of data, as compared to that using the mineral element data alone. The present study demonstrates that it is possible to indicate the poultry origin by applying stable isotope and multi-element analysis, which is an effective tool to trace the geographic origin of poultry.Keywords: stable isotope; multi-element; geographic origin; chicken Hoy en día es muy importante el establecimiento de métodos analíticos apropiados para autentificar el origen geográfico de la carne de ave de forma independiente a los estudios publicados. En este estudio, se analizaron los datos según el contenido de 2 isótopos estables (C y N) y 12 elementos minerales de muestras de pollo de 4 provincias para trazar su origen geográfico. Los resultados mostraron que la clasificación del pollo fue mejorada mediante la combinación de los dos tipos de datos, en comparación con la utilización única de elemento mineral. El presente estudio demuestra que es posible indicar el origen de las aves mediante la aplicación del análisis de isótopos estables y multielemento, el cual es una herramienta efectiva para trazar el origen geográfico de las aves.

“…Chemical fertilizers lead to lower δ 15 N values in plant that will translocate to chicken feed, and appear in chicken. Moreover, foraging of leguminous plant or feeding of leguminous feed will decrease the δ 15 N values in chicken (Bateman et al 2005;Yanagi et al 2012;Zhao et al 2013Zhao et al , 2014.

The objective of this study was to investigate the difference of chicken from organic and conventional systems. Chicken samples from three farms (Beijing conventional farm, Beijing organic farm, and Jilin organic farm) of each type were measured for contents of protein and fat, stable carbon and nitrogen isotope ratios, and concentrations of 12 mineral elements (Na, Mg, K, Ca, V, Fe, Co, Ni, Cu, Rb, Ba, and Pb). As a result, the chicken of two organic groups (Beijing organic and Jilin organic) yielded more protein than the Beijing conventional group. The nitrogen and carbon stable isotope ratios of de-fatted chicken from organic groups were higher than those of conventional ones. Mineral elements in de-fatted chicken samples showed significant differences (p < 0.05) except for Mg. The analysis data of stable isotope ratios and multielements were subjected to principal component analysis (PCA). The organic and conventional groups can be clearly classified through PCA. The combination of stable isotopes and multi-elements can further classify the geographical origin of chicken. The research work brought about a discovery of the difference between the organic and conventional chicken.

“…For these types of studies incremental tissues such as hair, wool or hoof, which contain a record of changes of diet over time, are more useful. Recently, many authors have shown that δ 13 C values and δ 15 N and δ 13 C values can be used to track the feeding system of the animal through an examination of incremental tissues.…”

Authenticity and quality of animal origin food investigated by stable‐isotope ratio analysis

Authentication of a food product is the procedure by which it is verified that the product matches the statements on the label, and that it conforms to what is established by regulations. This testing process includes analysis of the ingredients, determination of the geographical origin, and examination of the production methods. In particular, the use of rapid, effective and reliable analytical methods, when correctly applied to verify the authenticity and the traceability of the product, represents a valuable and irreplaceable tool for the authorities to carry out control functions. Tools and methodologies from scientific innovation and technological evolution can help to quickly locate particularly sophisticated frauds and adulterations. The feeding regime of livestock is a fundamental issue for the properties and safety of animal origin food, but this regime is often hidden from the consumer, making the zootechnical sector more prone to fraudulent practices. This review reports the results recently obtained in authentication of animal origin food by the application of stable-isotope ratio analysis, the most promising analytical technique in this field.
