applicazione dei metodi isotopici e dell’analisi sensoriale negli studi sull’origine dei vini

Abstract

Traceability of agro-alimentary products is very important to certify their origin. This work aimed to characterize wines obtained by the same cultivar (Nero d’Avola and Fiano) – grown in regions with different soil and climate conditions during three vintages (2003-2005) – employing isotopic analyses (NMR and IRMS) and sensory analyses. The effectiveness of stable isotopes ratios (D/H)1, 13C/12C and 18O/16O to assess the geographical origin of wines is affected by the natural variability of these parameters. Their usefulness in wine origin identification improves when they are used jointly. (D/H)1 and 18O/16O ratios depend on latitude but, in the meantime, 18O/16O is noticeably modified by the meteorological course during grape ripening. The most powerful ratios to discriminate between regions are (D/H)1 and 18O/16O (Versini and Monetti, 1996). The isotopic and the sensory analyses together allowed to distinguish wines from different regions.

Handbook of the charter of the universal holistic metaethics  sustainability 4.1c” for certification and warranty bio-métaétique 4.1c

Defined the new paradigm, the applied philosophy, the methodology, the algorithm of the “Charter for Universal Holistic MetaEthic Sustainability 4.1C17.18”, research has continued to define and write, an
handbook that should be:”Complete Universal Holistic MetaEthics 4.1C of descriptors” of the “Charter for Sustainability Universal Holistic MetaEthic 4.1C17.18” with basic and applicative indexing. In these activities and research we have involved over 3500 Italian and non-Italian people from the research world to simple but educated, enlightened and enlightening citizens and we have analyzed over 180000

ACCUMULATION OF GRAPE METABOLITES IS DIFFERENTLY IMPACTED BY WATER DEFICIT AT THE BERRY AND PLANT LEVELS IN NEW FUNGUS DISEASE-TOLERANT GENOTYPES

The use of new fungus disease-tolerant varieties is a promising long-term solution to better manage chemical input in viticulture, but unfortunately little is known regarding these new hybrids fruit development and metabolites accumulation in front of abiotic stresses such as water deficit (WD). Thus, prior to the adoption of such varieties by the wine industry in Mediterranean regions, there is a need to consider their suitability to WD.
