Investigation of Phenolic Components of Hungarian Wines
Ninety-two wines from the southernmost wine-producing region in Hungary (Villány) were analyzed for their polyphenolic content by high performance liquid chromatography (HPLC). Our results show that wine variety or vintage year could not be distinguished based on polyphenol content, but winery origin could be. Resveratrol concentration is mainly dependent on variety and vintage year. The “human...
متن کاملEvolution of analysis of polyhenols from grapes, wines, and extracts.
Grape and wine phenolics are structurally diverse, from simple molecules to oligomers and polymers usually designated as tannins. They have an important impact on the organoleptic properties of wines, that's why their analysis and quantification are of primordial importance. The extraction of phenolics from grapes and from wines is the first step involved in the analysis. Then, several analytic...
متن کاملDiversity of Candida zemplinina strains from grapes and Italian wines.
The aim of this research was to genetically and technologically characterize Candida zemplinina strains isolated from different sources of enological interest. Phenotypic and genotypic subtyping, as well as enological characterization, were carried out on 36 C. zemplinina isolates collected from grapes, must and wines of different regions of Italy. RAPD-PCR fingerprinting of the isolates reveal...

15 صفحه اولMetabonomic Investigation by H-NMR to Discriminate between Red Wines from Organic and Biodynamic Grapes
This study aimed to discriminate red wines obtained from organic and biodynamic management by means of proton nuclear magnetic resonance (H-NMR) and metabonomic investigation. Red wines were produced from Sangiovese grapes over the three harvests 2010-2012 from two parcels of a vineyard, managed according to organic (ORG) or biodynamic (BIO) protocol, respectively. Every year the vinifications ...
