Development of a standardized method for metabolite analysis by NMR to assess wine authenticity

Abstract

The wine sector generates a considerable amount of wealth but is facing a perpetual problem of fraud. Wine counterfeiting is one of the oldest and most common cases of food fraud worldwide. Therefore, the authenticity and traceability of wine are major concerns for both industry and consumers. To address these issues, robust and reliable analysis and control methods are necessary. Several methods have been developed, ranging from simple organoleptic tests to more advanced methodologies such as isotopic techniques or residual radioactivity measurements. However, with counterfeiting becoming increasingly sophisticated, more complex methodologies are needed for their detection. In this context, innovative tools for the analysis of metabolites and other small organic molecules can offer new perspectives for ensuring wine authenticity. In this work, we propose the development and validation of an open metabolomic approach based on 1H NMR to assess wine authenticity, using standardized, flexible, and accessible analytical and data processing protocols. Additionally, combinatorial approaches using orthogonal techniques e.g. NMR, high-resolution mass spectrometry, and data fusion are presented. These efforts represent a significant advancement towards establishing a standardized and open methodology for certifying wine authenticity using 1H NMR metabolomics and establish new metabolomic approaches for wine authentication and quality control.

Desarrollo de un método estandarizado mediante análisis metabolómico RMN para garantizar la autenticidad del vino

El sector vitivinícola genera una cantidad considerable de riqueza pero enfrenta un problema creciente de fraude. La falsificación de vinos es uno de los casos más antiguos y comunes de fraude alimentario en todo el mundo. Por lo tanto, la autenticidad y trazabilidad del vino son preocupaciones importantes tanto para la industria como para los consumidores. Para abordar estos problemas, son necesarios métodos de análisis y control robustos y confiables. Se han desarrollado varios métodos, que van desde simples pruebas organolépticas hasta metodologías más avanzadas como técnicas isotópicas o mediciones de radiactividad residual. Sin embargo, con la falsificación volviéndose cada vez más sofisticada, se necesitan metodologías más complejas para su detección. En este contexto, las aplicaciones innovadoras de herramientas metabolómicas pueden ofrecer nuevas perspectivas para garantizar la autenticidad del vino.  En este trabajo, proponemos el desarrollo y validación de un método metabolómico abierto basado en rmn 1h para garantizar la autenticidad del vino, utilizando protocolos estandarizados, flexibles y accesibles. Estos esfuerzos representan un avance significativo hacia el establecimiento de una metodología estandarizada y abierta para certificar la autenticidad del vino utilizando metabolómica de rmn 1h.  Además, se están explorando otros métodos, como la combinación de análisis por rmn, espectrometría de masas de alta resolución y fusión de datos. Este estudio abre el camino para nuevos métodos metabolómicos para la autenticación y el control de calidad del vino.

Développement d’une méthode standardisée par analyse métabolomique RMN pour garantir l’authenticité des vins

Le secteur viticole génère une grande quantité de richesse, mais doit faire face à un problème croissant de fraudes. La contrefaçon des vins est l’un des cas les plus anciens et les plus courants de fraude alimentaire dans le monde. Par conséquent, l’authenticité et la traçabilité du vin sont des enjeux majeurs pour la filière et les consommateurs. Pour répondre à ces enjeux, il est nécessaire de disposer de méthodes d’analyse et de contrôle robustes et fiables. Plusieurs méthodes ont été développées, allant de simples tests organoleptiques à des méthodologies plus avancées telles que les techniques isotopiques, ou les mesures de radioactivité résiduelle. Cependant, avec des contrefaçons devenant de plus en plus sophistiquées, des méthodologies plus complexes sont nécessaires pour leur détection. Dans ce contexte, des applications innovantes des outils de la métabolomique peuvent offrir de nouvelles perspectives pour assurer l’authenticité du vin.   Dans ce travail, nous proposons le développement et la validation d’une approche métabolomique ouverte basée sur la rmn 1h pour garantir l’authenticité du vin, en utilisant des protocoles standardisés flexibles et accessibles. Ces travaux représentent une avancée significative vers l’établissement d’une méthodologie normalisée et ouverte pour la certification de l’authenticité d’un vin en utilisant la métabolomique rmn 1h.   De plus, d’autres approches sont en cours d’exploration comme la combinaison des analyses par rmn, spectrométrie de masse à haute résolution et fusion de données. Cette étude ouvre la voie à de nouvelles approches métabolomiques pour l’authentification et le contrôle de la qualité du vin.

Application of cyclic voltammetry to the classification of enological tannins in relationship to oxygen consumption rate and botanical origin 

Enological tannins are a diversified group of winemaking products that vary in several aspects such as chemical composition, botanical origin, and production method. In consideration of their richness in phenolic compounds, one of their main application in vinification is related to their antioxidant capacity, in particular their ability to consume oxygen during red wine maturation.

Understanding the physiological responses of Sauvignon blanc vines to sequential extreme weather events: implications for vineyard management in a changing climate

Climate plays a predominant role in vines’ growth and productivity and several environmental variables are already known to pose challenges to grapevine production and the horticultural industry as a whole. In this context, a number of extreme weather events already occurring and expected to occur in the next decades even more frequently and with higher magnitude results from current climate change scenario. The aim of this study was to examine the physiological responses of roots, leaves, and berries of Vitis vinifera cv. Sauvignon blanc to consecutive and combined stressors simulated in a semi-controlled environment.

An effective approach to mitigating ochratoxin A (OTA) levels in wine with minor impact on wine quality

OTA occurrence in wine is well-documented, with higher levels typically found in red (< 0.01-7.63 μg/l), followed by rose (0.01-2.40 μg/l) and white wine (<0.01-1.72 μg/l). Incidence rates are nOTAble, with studies showing OTA present in 53% of 521 red wines, 69% of 98 rose, and 61% of 301 white wines analysed. In europe, wine is estimated to be the second source of OTA intake after cereals. Since 2006, the maximum allowable limit for OTA in wine is 2 μg/l, according to regulation (ec) no. 1881/2006.

Assessment of antimicrobial effect of chitosan extracted from different sources against unwanted wine microorganisms

During wine production process high attention to the microbiological control from fermentation of the grape must to bottling is necessary. In fact, control of the indigenous microflora of the grape ensures correct fermentation activity of the inoculated starter, while control of the microorganisms in the finished wine is essential to prevent wine spoilage and to ensure the dominance of the desired bacteria when malolactic fermentation is required (Mas and Portillo, 2022).

Emosensory profile and chemical characterization of wine vinegar from the Douro and Rioja demarcated regions

Wine vinegars have a tangy flavor and are versatile in cooking. They’ve been used since the neolithic period and are now used as microbial inhibitors and acidifiers. They’re low in calories, have antioxidants, and have a long shelf life, but quality may decrease after opening. The objective of this study focuses on the physical-chemical, sensory, and emotional characterization of wine vinegar samples from the douro demarcated region and la rioja. In total, 22 samples of wine vinegar were analyzed at the time of opening.
