“…This type of approach has been frequently used to study various aspects of foods, such as pedoclimatic factors (olive oil [78][79][80]), geographical origin (wines [81][82][83], olive oils [84][85][86]), botanical origin (honey [34,87]), ripening (kiwi [21], tomatoes [88,89], pistachio [90]), postharvest changes (kiwi [18], banana [91]), and the manufacturer (beer [92]). Food authenticity (wine [93][94][95], honey [32,96], coffee [97]) has been also studied with the described untargeted approach.…”

In this review, the three different NMR-based approaches usually used to study foodstuffs are described, reporting specific examples. The first approach starts with the food of interest that can be investigated using different complementary NMR methodologies to obtain a comprehensive picture of food composition and structure; another approach starts with the specific problem related to a given food (frauds, safety, traceability, geographical and botanical origin, farming methods, food processing, maturation and ageing, etc.) that can be addressed by choosing the most suitable NMR methodology; finally, it is possible to start from a single NMR methodology, developing a broad range of applications to tackle common food-related challenges and different aspects related to foods.

“…Typically, untargeted methods consist in transforming 1 H-NMR wine spectra into matrices of data by what is known as binning or bucketing (Ehlers et al, 2022). Each bin (bucket) represents a small area of the spectrum (between 0.01 and 0.05 ppm).…”

<sup>1</sup>H-NMR metabolomics for wine screening and analysis

The number of metabolomic studies has grown steadily over the last twenty years. Among the fields of application, food sciences are broadly represented. Proton NMR (1H-NMR) is a commonly used technique for metabolomics and is particularly suitable for wine analysis, because the major wine constituents are highly dependent on biotic and abiotic conditions. 1H-NMR-based metabolomics were used first to guarantee the authenticity of wines, and more recently to determine the impact of viticultural or oenological practices using both targeted and untargeted protocols. This state-of-the-art review covers the different analytical methodologies developed to ensure wine traceability from sample preparation to 1H-NMR spectrum analysis. The potential applications of 1H-NMR spectroscopy in oenology, from wine authenticity control to the monitoring of winemaking, are described. The challenges and perspectives of the deployment of NMR for oenological monitoring are also discussed.

“…NMR spectroscopy is an analytical method based on the magnetic properties of certain nuclei that provides structural and quantitative information on molecules in a nondestructive, effective, and rapid way [49]. Several studies have recently applied NMR spectroscopy for the authentication of different food products [14,[50][51][52]. In the case of berries, NMR spectroscopy coupled with chemometric tools has been used to evaluate the influence of soil, vintage, growing areas, and growing systems on the metabolic profile of grape berries.…”

The health-related properties attributed to berries and the subsequent interest awakened within the market of functional foods mean that these small fruits may be potential targets for food fraud. In this review, studies on berry authentication through modern analytical techniques are discussed in detail. Most of the studies reported to date are related to chemical approaches, mainly chromatographic techniques. Other chemical (NMR, NIR, and Raman spectroscopy), biomolecular, and isotopic methods have also delivered promising results in the field of berry authentication, although there is still limited information available in this respect. Despite the potential of the methods described in the present review, to date, there is no universal one. Therefore, combinations of different approaches in order to complement each other are increasingly used (e.g., HPTLC and mass spectrometry; Raman and IR spectroscopies; biomolecular and analytical techniques…). Considering that adulteration practices are increasingly evolving, continuous research in the field of food authentication is needed, especially in the case of berries, since there are still some berry species that have not yet been included in any authentication study.
