Determinazione della frazione aromatica dei vini, quale strumento per-la valorizzazione del territorio viticolo

Abstract

[English version below]

La caratterizzazione della frazione volatile aromatica dei vini attraverso l’analisi quali­quantitativa dei diversi composti, ha portato corne primo risultato la netta differenziazione delle annate in prova.
Dalla relazione tra analisi sensoriale e analisi chimica, è poi risultato che, per il vino Soave, esteri etilici e acetati sono i composti organoletticamente più importanti e responsabili del-l’aroma fruttato floreale. Alcoli e acidi sono apparsi invece meno utili e sicuri nella caratte­rizzazione varietale e ambientale. E’ quindi importante per ogni vino conoscere i composti aromatici tipici e i loro responsabili analitici, sulla base poi della quantificazione di questi ultimi sarà possibile una caratterizzazione ambientale.

The qualitative and quantitative analysis of the volatile aromatic components of wine has produced, as a first result, a net differentiation of the years being tested.
From the correlation between sensory and chemical analysis we have also found , for Soave wine, that acetates and esters are the most important sensory components; they are responsable for the fruit and floral aromas of wine.
However, alcohols and acids have shown to be less useful in varietal and environmental characterization. It is therefore very important to know, for each wine, the typical aromatic compounds and their chemical composition, and based on their quantification it is possible to value the environment.

Ability of lactic acid bacterial laccases to degrade biogenic amines and OTA in wine

Two of the most harmful microbial metabolites for human health that can be present in wines and either fermented or raw foods are biogenic amines (BA) and ochratoxine A (OTA). Winemakers are aware of the need to avoid their presence in wine by using different strategies, one of them is the use of enzymes. Some recombinant laccases have been characterized and revealed as potential tools to degrade these toxic compounds in wine[1], specifically biogenic amines[2].

Characterization of the Origin Denomination “Ribeira Sacra”

“Ribeira Sacra” is an origin denomination located between the provinces of Lugo and Ourense, in Galicia (northwest of Spain).

ABA and ethephon alleviated to a different extent the impact of elevated temperatures on grape berry composition

The Intergovernmental Panel on Climate Change (IPCC) forecasts an increase in global temperature and a decrease in relative humidity (RH) in the coming decades, which may have implications for berry ripening and composition.

NACs intra-family hierarchical transcriptional regulatory network orchestrating grape berry ripening

Considering that global warming is changing berry ripening timing and progression, uncovering the molecular mechanisms and identifying key regulators governing berry ripening could provide important tools in maintaining high quality grapes and wine. NAC (NAM/ATAF/CUC) transcription factors represent an interesting family due to their key role in the developmental processes control, such as fruit-ripening-associated genes expression, and in the regulation of multiple stress responses. Between the 74 NAC family members, we selected 12 of them as putative regulators of berry ripening: NAC01, NAC03, NAC05, NAC11, NAC13, NAC17, NAC18, NAC26, NAC33, NAC37, NAC60 and NAC61.

Terroir, climat et sol

Le sol et le climat occupent une place prépondérante dans le concept de terroir, pour lequel l’OIV s’apprête à adopter une définition internationale. Les travaux de recherche qui ont été menés depuis une trentaine d’années sur ces thèmes et qui ont été, pour les plus importants, présentés dans les 7 premiers Congrès Internationaux des Terroirs Viticoles ont considérablement modifié les connaissances sur le fonctionnement des terroirs viticoles dans le monde et le comportement des consommateurs avertis par rapport aux vins de terroirs.
