“…The majority of the food samples were reflective of C3 plants (Fig 1A). Generally, the results indicated that Koreans consume a wide variety of foods, inclusive of C3 and C4 plants [33][34][35][36][37], because the δ 13 C values from hair samples corresponded to the mid-range value between C3 and C4 plants. The typical δ 13 C ranges of C3 plants and C4 plants are -33 ‰ to -23 ‰ and -16 ‰ to -9 ‰, respectively [36].…”

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.

“…Powdered sample (0.3 mg) was placed in a tin capsule on an elemental analyser coupled with an IR mass spectrometer (Vario Isotope Cube‐Isoprime, Elementar) (Park et al., 2019) to measure the values of δ 13 C and δ 15 N. The stable isotope values of carbon and nitrogen were expressed as δ i E = [( R sample/ R standard) – 1] × 10 3 ‰, where E represents the element C or N, i represents the mass number of the heavier isotope of element E, R sample represents the 13 C/ 12 C ratio or 15 N/ 14 N ratio of the sample, and R REF represents the ratio of the relevant internationally recognized reference material (Bontempo et al., 2019; Camin et al., 2017). The δ 13 C and δ 15 N values were calibrated with the certified reference material acetanilide, which had a δ 13 C value of − 29.53‰ relative to the Vienna Pee Dee Belemnite standard (PDB) and a δ 15 N value of 1.18‰ relative to the abundance of N 2 in air.…”

The two whelks Rapana venosa and Neptunea arthritica cumingii are important fishery resources, but the biomass of these species has declined extensively over the years. In the present study, we selected the sea area around Zhangzi Island, a typical North China Sea island, as the study area. Biochemical trophic markers (stable isotopes and fatty acids (FAs)) were used to estimate the dietary compositions of R. venosa and N. arthritica cumingii. The combined use of stable isotope analysis and analysis of FA composition enabled a comprehensive investigation of these species in the North China Sea. The results showed that the two whelk species were significantly distinguished by their FAs, suggesting that dietary composition significantly differs between the two species; however, the values of C22:6(n‐3) (DHA)/C20:5(n‐3) (EPA) and δ15N indicated no significant difference between the two whelk species at the trophic level. The EPA content of N. arthritica cumingii was higher than that of R. venosa, indicating that the former species is more involved in the scavenger food chain, although this FA species represented a small proportion of the dietary composition in both whelk species. In contrast, there were no significant differences in stable isotope ratios or FA contents among different size classes of the same whelk species. This study provides insight into the structural changes and dynamics of marine communities. Such information is essential for the protection of fishery resources, their sustainable development and utilization, and the scientific management of marine ecosystems.

“…In particular, the δ 15 N and δ 18 O values were critical isotope markers for an obvious geographical origin discrimination between mushrooms produced in Korea and China, as shown in Figure 6. Ratios of stable isotopes of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S) were used for the evaluation of the geographical origin of onion cultivated in various regions of Korea by Park et al [16]. They concluded that this technique has high potential for discriminating onions produced in Korea from those produced in other countries and more distinct geographical differentiation of onion origin could be achieved by additional multi-elemental analysis.…”

This study is a systematic literature review of geographical origin authentication by elemental analytical techniques. Authentication and certification of geographic origin of agri-food products is a useful tool toward the protection of the quality for products. The aim of this work was to map the current state of research in the area of agricultural products and food, identifying emerging fields to the geographical origin of products. The article is divided in three parts. The first part of the article deals with the analytical techniques applied in the food authentication. Special mention is made to elemental analysis and multiple isotope ratio. The second section focuses on statistically published data concerning published research for geographical origin authentication for the period 2015–2019. Specific results are presented inter alia: number of articles according to the type of product, articles according to the type of the analytical techniques, and others. The third part contains characteristic results from articles that were published in the period 2015–2019, on certification of geographical origin on specific agricultural products.
