“…The mean δ 34 S value was +7.3 ± 0.8 ‰ (range: +3.4 to +10.0 ‰). The δ 13 C, δ 15 N, and δ 34 S values obtained from food from local stores and supermarkets are shown in Table 2 [25][26][27][28][29][30][31][32].…”

Dietary homogenization has progressed worldwide due to westernization and the globalization of food production systems. We investigated dietary heterogeneity in South Korea by examining the spatial distribution of carbon (C), nitrogen (N), and sulfur (S) isotope ratios using 264 human hair samples. Overall, variation in isotope values was small, indicating low dietary heterogeneity. We detected differences in δ13C, δ15N, and δ34S values between administrative provinces and metropolitan cities; inter-regional differences were typically < 1 ‰. Values of δ34S were significantly lower in hair samples from inland regions relative to those from coastal locations, and a similar pattern was observed in δ15N values. Understanding geographic variation in δ34S and δ15N values in human hair is useful for provenancing humans in South Korea.

“…The analysis showed a clear separation in the origin of meat from three regions: South Korea, America and Europe. Researchers also identified similar δ 13 С results for the USA and Mexico: minus 14.78‰ and minus 14.81‰, respectively, for Holland and Denmark: minus 25.57‰ and minus 25.24‰, respectively, due to their geographical proximity [33].…”

KEY WORDS: controlled origin place, isotopic mass spectrometry, elemental profile, stable isotope ratio A BST R ACT Food products with controlled geographical origin place are in special demand among consumers because of their specific properties, due to climatic, soil characteristics or other factors. The article provides an analysis of regulatory framework for legal goods protection with an indication of their origin place on the territory of the Russian Federation and in other countries. Existing authentication methods for this type of product are reviewed. Based on the analysis of scientific literature, the authors noted the most significant works aimed at confirming the authenticity of food products' origin place on the example of honey and meat products, which were carried out in the countries of the European Union, Australia, China, Brazil, South Africa, the USA and other countries. It is shown that the most widespread researches aimed at studying values of isotopic ratios of hydrogen ( 2 H/ 1 H), carbon ( 13 C/ 12 C), oxygen ( 18 O/ 16 O), nitrogen ( 15 N/ 14 N) and sulfur ( 34 S/ 32 S) in compounds contained in products that reflect the distribution of «light» and «heavy» isotopes during biological and geochemical processes within a single region. The analysis of the works aimed at studying the qualitative and quantitative composition of trace elements and rare earth metals (As, B, Ba, Cd, Li, Mn, Pd, Rb, Se, Te, Tl, Dy, U, etc.), as well as research of isotopic relations values of some elements ( 87 Sr/ 86 Sr, 207 Pb/ 206 Pb, etc.) in product samples and soils of studied region. The advantages of an integrated research approach, which includes the creation of data array of various indicators values and its in-depth analysis using chemometric algorithms and mathematical modeling methods, are shown.Despite the fact that values of such isotopic ratios as 87 Sr/ 86 Sr, 207 Pb/ 206 Pb, 208 Pb/ 206 Pb, and 204 Pb/ 206 Pb are also quite informative indicators when determining food products territorial affiliation, their scientists use much less often [65]. ConclusionThe results of numerous researches show that studying isotopic ratios of the main biophilic elements and elemental profile are powerful tools in confirming geographical origin place of food products. The values of isotopic ratios of hydrogen ( 2 H/ 1 H), carbon ( 13 C/ 12 C), oxygen ( 18 O/ 16 O), nitrogen ( 15 N/ 14 N) and sulfur ( 34 S/ 32 S) in compounds that make up food products are largely determined by climatic and geographical conditions of raw materials growth region. The qualitative and quantitative composition of trace elements and rare-earth metals (As, B, Ba, Cd, Li, Mn, Pd, Rb, Se, Te, Tl, Dy, U, etc.), as well as values of isotopic ratios of some metals ( 87 Sr/ 86 Sr, 207 Pb/ 206 Pb, etc.) reflect the specific terroir of researched region. Using the described research methods in combination with the methods of mathematical results processing (ANOVA, PCA, LDA, etc.) allows to confirm with high accuracy of the product belongs to spe...

“…They have given significant contributions regarding lamb meat [102,103], poultry, beef meat [104][105][106][107][108][109] and pork meat [110]. These studies can be roughly subdivided into two types: the first employs stable isotope ratios, in particular δ 13 C and δ 18 O, sometimes together with multi-elemental analysis and with the use of elemental analyser-isotope ratio mass spectrometry (IR-MS); the second employs the 87 Sr/ 86 Sr isotope ratio with the use of thermal ionization mass spectrometry (TIMS).…”

and ends with man. The environment-food interaction is clear, and the production of safe and quality food is an indispensable condition for human health. The globalization of the markets, in particular of food markets, means that a greater variety of food is proposed to consumers who want to know more about its geographical origin and characteristics. For this aim, food traceability is a tool of primary importance because it acts on both food safety and quality, in order to satisfy the needs of a demanding consumer, who is interested in the quality of the food he eats and in the controls about the veracity of the brands which protect it [1, 2]. The production of high-quality food is the first step to satisfying other important aspects, such as the development of a productive but sustainable agriculture and the control of marketing. Frequently, all this is delegated to the "labelling", which is incomplete by nature or easily manipulated. Only the use of a scientific method of identification and control of the geographical origin, independent of the "labelling" and therefore of the producer, enables us to answer in full important questions concerning food safety, food quality and consumer protection. In order to achieve good results in this field, a basic mandatory condition is to develop suitable "robust" analytical methods which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds; the latter are fuelled by the modern ease of transport and conservation of products in world markets. Numerous chemical, biological and genetic methods have been developed over time in order to verify the origin of foods [3]. In this paper, we will focus on mass spectrometry, in particular on the 87 Sr/ 86 Sr isotopic ratio measurement, in that it is a "robust" analytical technique, able to fulfil the requisites needed for traceability, both to satisfy the veracity of the geographical origin and to trace possible contaminated foods back to their origin. In particular, due Abstract Today, food traceability needs to develop suitable "robust" analytical methods, in terms of the precision and of the reliability of results, which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds. This review paper highlights the most recent results obtained with the use of the 87 Sr/ 86 Sr isotopic ratio technique, when applied to the traceability of the origin of different foods for human consumption, such as vegetables, beverages, dairy products, and meat and fish products. The instrumental techniques, with the relative methodologies and the quality of the final results, will be examined and commented.
