A novel approach for the identification of new biomarkers of wine consumption in human urine using untargeted metabolomics

Abstract

Wine is one of the most representative components of Mediterranean diet. Moderate wine intake together with food, has been positively correlated with reduced risk of many chronic diseases. This beneficial effect seems to be ascribed to elevated polyphenolic content of wine [1]. Traditional approaches for the identification of wine biomarkers consumption include targeted metabolomics that focuses on the quantification of well-defined metabolites, losing a valuable information about a massive number of compounds. On the other hand, untargeted metabolomics can disclose a large quantity of signals corresponding to potential biomarkers in a single analysis with high sensitivity and resolution. This work focuses on the identification of wine intake biomarkers in 24-h urine samples of free-living volunteers using untargeted metabolomics approach. Two groups were included: (i) volunteers with daily and moderate wine consumption, and (ii) control group, volunteers who never drink wine. Urine samples (24-h) were analysed by liquid chromatography coupled with high-resolution mass spectrometry (UPLC-QToF), using two stationary phases (RP and HILIC) to separate metabolites of different polarities, moreover all the analyses were done in both positive and negative ionization modes. The most significant compounds highlighted after performing an OPLS-DA were tentatively identified based on their accurate masses and spectra information. Different metabolites associated with wine intake have been tentatively proposed, such as aminoacids and peptides, and different phenol metabolites.

Aroma characterization of mold resistant base wines for sparkling wine produced in a warm-temperate area at two different altitudes

In a recent context where consumers pay an increasing attention to sustainability and eco-friendly aspects in the decision-making process, the use of the resistant varieties in the wine sector have returned to the attention. In this context, the use of mould-resistant grape varieties would be an opportunity for sparkling wine producers as it can reduced the pesticide utilization in grape management and hence production costs.
However, the use of the resistant varieties to produce the base wine may be strongly influenced due to its requirements for a particular balance between sugars and acidity to ensure the quality of the final product. In addition, the aromatic profile of base wine plays a crucial role in the perception of the quality of the sparkling wine.

Effect of spray with autochthonous Trichoderma strains and its secondary metabolites on the quality of Tempranillo grape

Trichoderma is one of the most widely used fungal biocontrol agents on vineyards due to its multiple benefits on this crop, such as its fungicidal and growth promoting capacity. In this work, we have analyzed the effect on the concentration of nutrients in grapevine leaves and on the quality of the grape must after spraying an autochthonous strain of Trichoderma harzianum and one of the main secondary metabolites produced by this genus, 6-pentyl-α-pyrone (6PP).

Volatile composition of Cabernet Sauvignon wines from Argentina, Portugal and Spain

Cabernet Sauvignon is one of the most cultivated grape varieties worldwide being grown in different environmental conditions due to its excellent adaptability. Volatile compounds deeply contribute to the sensory properties of wines therefore to wine quality. The aim of this work was to compare the aroma profile of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain, from the vintage 2022. In addition, the volatile composition of the Cabernet Sauvignon Portuguese wines from three vintages was evaluated.

Effect of rising atmospheric CO2 levels on grapevine yield and composition by the middle of the 21st century: what can we learn from the VineyardFACE?

Atmospheric CO2 levels have been rising continuously since the industrial revolution, affecting crop physiology, yield and quality of harvest products, and grapevine is no exception [1]. Most of previously reported studies used potted plants in controlled environments, and explored grapevine response to relatively high CO2 levels, 700 ppm or more. The vineyardFACE, established in Geisenheim in 2012, uses a free air carbon dioxide enrichment (FACE) system to simulate a moderate (ambient +20%) increase in atmospheric CO2 in a vineyard planted with cvs. Cabernet-Sauvignon and Riesling grafted on rootstock 161-49 Couderc and SO4, respectively.
