“…The fingerprinting methods based on mineral element composition of food stuff have been largely adopted in the last years to trace the geographical origin of wine, olive oil, honey, cheese, coffee, vegetable, fruits, and spices (Danezis et al, 2016). One of the most popular techniques adopted for these analyses is the inductively-coupled plasma mass spectrometry (ICP-MS), which can be used for the determination of both the ionomic profile and the isotope ratios (Baxter et al, 1997; Rebolo et al, 2000; Wieser et al, 2001; Castiñeira et al, 2004; Coetzee et al, 2005; Šelih et al, 2014; Capici et al, 2015; Mimmo et al, 2015; Popescu et al, 2015; Scampicchio et al, 2016). …”

The determination of food geographical origin has been an important subject of study over the past decade, with an increasing number of analytical techniques being developed to determine the provenance of agricultural products. Agricultural soils can differ for the composition and the relative quantities of mineral nutrients and trace elements whose bioavailability depends on soil properties. Therefore, the ionome of fruits, vegetables and derived products can reflect the mineral composition of the growth substrate. Multi-elemental analysis has been successfully applied to trace the provenance of wines from different countries or different wine-producing regions. However, winemaking process and environmental and cultural conditions may affect a geographical fingerprint. In this article, we discuss the possibility of applying ionomics in wines classification on a local scale and also by exploiting grape berry analyses. In this regard, we present the ionomic profile of grapevine berries grown within an area of approximately 300 km2 and the subsequent application of chemometric methods for the assignment of their geographical origin. The best discrimination was obtained by using a dataset composed only of rare earth elements. Considering the experiences reported in the literature and our results, we concluded that sample representativeness and the application of a preliminary Principal Component Analysis, as pattern recognition techniques, might represent two necessary starting points for the geographical determination of the geographical origin of grape berries; therefore, on the basis of these observations we also include some recommendations to be considered for future application of these techniques for grape and wines classification.

“…In our study, δ 15 N values ranged from -0.5 to 9.2 ‰ with a mean value of 2.4 ‰, which is lower than the soil δ 15 N value. Mimmo et al [25] observed similar values, ranging between 1.1 and 3.0 ‰. We could not differentiate between different postal code regions on the basis of δ 15 N values in apples.…”

“…Geological background, altitude [15], climate [16] and precipitation [17,18] cause a natural geographic variance in isotope ratios, but these are consistent within a given area. While stable water isotopes ( 2 H and 18 O) are suitable for differentiating large-scale regions [19,20], 13 C, 15 N and 34 S isotopes provide details of product origins on smaller scale [9,[21][22][23][24][25][26].

As demand for regional and organically produced foodstuff has increased in Europe, the need has arisen to verify the products' origin and production method. For food authenticity tracking (production method and origin), we examined 286 samples of wheat (Triticum aestivum), potatoes (Solanum tuberosum), and apples (Malus domestica) from different regions in Germany for their stable isotope compositions of oxygen, hydrogen, carbon, nitrogen and sulphur. Single-variate authentication methods were used. Suitable isotope tracers to determine wheat's regional origin were δ 18 O and δ 34 S. δ 13 C helped to distinguish between organic and conventional wheat samples. For the separation of the production regions of potatoes, several isotope tracers were suitable (e.g. δ 18 O, δ 2 H, δ 15 N, δ 13 C and δ 34 S isotopes in potato protein), but only protein δ 15 N was suitable to differentiate between organic and conventional potato samples. For the apple samples, 2 H and 18 O isotopes helped to identify production regions, but no significant statistical differences could be found between organically and conventionally farmed apples. For food authenticity tracking, our study showed the need to take the various isotopes into account. There is an urgent need for a broad reference database if isotope measurements are to become a main tool for determining product's origin.

“…However, other factors, such as variety or site of production, could be more significant parameters influencing δ 13 C values in the section on botanical origin 34 . Another study performed on the whole apple fruits and three sub‐fractions (peel, pulp and seed) showed that δ 13 C and δ 15 N values were also able to discriminate apple varieties, but only when small geographical areas were considered 35 …”

BACKGROUND With increasing attention being paid to food authenticity, the geographic origin of food has become a topic of interest for both consumers and producers. As far as we know, there are relatively few studies on the origin traceability of concentrated apple juice. The most commonly used methods of origin tracing research is by using stable isotopes and mineral elements technology, because these indicators are directly related to local geographical environment. RESULTS In this study, a discriminant model was established by determining the content of the stable isotopes (δ13C, δ18O) and 13 mineral elements (B, Mn, Co, Ni, Cu, Sr, V, Ba, Fe, Mg, Na, Ca and Cr) in concentrated apple juice. Linear discriminant analysis (LDA), principal component analysis (PCA) and partial least squares discriminant analysis (PLS‐DA) were employed for regional classification of samples. After data conversion and correlation analysis, spatial and quantitative prediction models were established using multiple linear regressions. Finally, the experimental results showed that the eight key variables(δ 13 C, δ 18 O, B, Ca, Mg, Cu, Sr and Na) selected by the analysis can be used to further characterize the production area. CONCLUSION The results showed that the carbon and oxygen isotopes combined with certain mineral elements can be used to indicate the origin of concentrated apple juice. © 2020 Society of Chemical Industry

Traceability of different apple varieties by multivariate analysis of isotope ratio mass spectrometry data

Abstract: This study proves the potential of stable isotopes to discriminate the geographical origin of apples grown in orchards located only a few hundreds of kilometres apart. Stable isotopes were also able to discriminate different apple varieties, although only within small geographical areas.
