Geographical origin identification of garlic cultivated in Korea using isotopic and multi-elemental analyses

Dietary homogenization and spatial distributions of carbon, nitrogen, and sulfur isotope ratios in human hair in South Korea

“…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].…”

“…We found no significant difference in the intake rate of animal and marine foods between metropolitan cities and administrative provinces in South Korea. On average, animal and marine food intake is reportedly only 1.2% higher in metropolitan cities in South Korea [37]. Data regarding the intake rates of animal and marine products were not available for all administrative provinces considered here.…”

Preliminary Study on Tracing the Origin and Exploring the Relations between Growing Conditions and Isotopic and Elemental Fingerprints of Organic and Conventional Cavendish Bananas (Musa spp.)

“…Most of the published research focused on the discrimination of geographical origin and production system, while only a few research studies aimed to explore the underlining reasons that foods have various composition differences according to different origins and production systems. There are already studies which reported that the lithological properties of origin could change the element contents of garlic [ 23 ], while latitudes had significant influences on the depleted δ 2 H and δ 18 O values of poultry [ 24 ]. Our previous study revealed that the isotopic ratios and elemental profiles of bananas were highly related to climate, topography and soil conditions in a single country [ 25 ].…”

Classification of organic and ordinary kiwifruit by chemometrics analysis of elemental fingerprint and stable isotopic ratios

“…In recent years, element fingerprints and stable isotope ratio methods have been widely used in food traceability (Choi et al., 2020; Gonzalvez et al., 2009) and proved to be powerful tools to classify geographical origins (Cantarelli et al., 2011), cultivars, species, and frauds (He et al., 2020; Zhang et al., 2020; Imaizumi et al., 2019). As an effective data analysis method, chemometrics is also widely popularized in the identification of food origin and quality (Zaukuu, et al., 2019; Monteiro, et al., 2019; Baqueta et al., 2019; de Carvalho et al., 2020).…”
