Impact of Oak Wood Barrel Tannin Potential and Toasting on White Wine Antioxidant Stability
2019
International audience; Wines aged in oak wood barrels with various uniform tannin contents (which were classified according to their total ellagitannins contents as predicted by Near Infrared Spectroscopy on the untoasted wood) and different toasting levels (high precision toasting by radiation) were distinguished according to their overall abilities to resist against oxidation. Wine trials were carried out on two different vintages (2015, 2016) and three grape varieties (Sauvignon blanc, Sémillon, Chardonnay). Regardless of the vintage and the wine matrix, a relationship was established between wine oxidative stability (based on EPR spin trapping methodology) and oak barrel tannin potenti…
Inoculation of Torulaspora delbrueckii as a bio-protection agent in winemaking
2018
International audience; In oenology, bio-protection consists in adding bacteria, yeasts or a mixture of microorganisms on grape must before fermentation in order to reduce the use of chemical compounds such as sulphites. More particularly, non-Saccharvinyces yeasts are used as a total or partial alternative to sulphites. However, scientific data capable of proving the effectiveness of adding these yeasts on grape must is lacking. This study reports the analysis of antimicrobial and antioxidant effects of one non-Saccharamyces yeast, Torulaspora delbruecicii, inoculated at the beginning of the white winemaldng process in two Burgundian wineries as an alternative to sulphiting. The implantati…
Etusivun politiikkaa : yhteiskunnallisten toimijoiden representointi suomalaisissa sanomalehtiuutisissa 1987-2003
2004
FL Jukka Holmbergin journalistiikan väitöskirjan ”Etusivun politiikkaa. Yhteiskunnallisten toimijoiden representointi suomalaisissa sanomalehtiuutisissa 1987-2003.” tarkastustilaisuus. Vastaväittäjänä professori Pertti Suhonen (Tampereen yliopisto) ja kustoksena professori Raimo Salokangas.Jukka Holmberg tutki puoluetaustan ja sitoutumattomuuden vaikutusta sanomalehtien pääuutissivujen politiikan uutisiin 1980-luvun lopulta 2000-luvulle tultaessa eli aikana, jolloin Suomessa siirryttiin puoluepohjaisen lehdistöjärjestelmän loppuvaiheista täysin markkinavetoiseen järjestelmään. The research assesses the development of subjectivity and partiality in Finnish political journalism as the party p…
Ús del programa Berkeley Madonna per al desenvolupament de models en la docència en Enginyeria Química
2014
La modelització és un procediment metodològic fonamental per a resoldre problemes en enginyeria. Consisteix en representar el problema d'una forma adequada, de manera que s'aconsegueixi una substitució del sistema real per altre més adequat que permeti el tractament formal. És per això que el seu aprenentatge és molt important en l'estudi de l'Enginyeria Química i s'emmarca en les competències contingudes en el mòdul de tecnologia específica, Química Industrial (Ordre CIN/351/2009). En el present treball, es proposa l'ús del programa informàtic Berkeley Madonna per a l'estudi de la modelització del creixement bacterià sobre un o diversos substrats en l'assignatura Processos Biotecnològics d…
Description de la typicite aromatique de vins de bourgogne issus du cepage chardonnay
1993
<p style="text-align: justify;">La typicité aromatique de 23 vins blancs de Bourgogne issus du cépage Chardonnay est évaluée par 32 oenologues au cours de 3 séances. De manière indépendante, une caractérisation de l'odeur et de l'arôme de chaque vin est fournie par chaque sujet sous la forme d'un choix libre de 5 descripteurs au plus.</p><p style="text-align: justify;">Les vins se répartissent selon 3 groupes de typicité croissante sans rapport net avec les appellations. Sept descripteurs-clefs de l'odeur et de l'arôme du Chardonnay de Bourgogne s'imposent: miel, vanille, pain grillé, beurre frais, boisé, floral et noisette. De plus, une liste de 9 autres descripteurs auxi…
The Antioxidant Potential of White Wines Relies on the Chemistry of Sulfur-Containing Compounds: An Optimized DPPH Assay
2019
The DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay is an easy and efficient method commonly used to determine the antioxidant capacity of many food matrices and beverages. In contrast with red wines, white wines are poorer in antioxidant polyphenolics, and the more hydrophilic sulfur-containing compounds in them may contribute significantly to their antioxidant capacity. The modification of the classical DPPH method, with a methanol-buffer and the measure of EC20 (quantity of sample needed to decrease the initial DPPH concentration by 20%) has shown that sulfur-containing compounds such as cysteine (0.037 ±
Molecular Characterization of White Wines Antioxidant Metabolome by Ultra High Performance Liquid Chromatography High-Resolution Mass Spectrometry
2020
International audience; The knowledge about the molecular fraction contributing to white wines oxidative stability is still poorly understood. However, the role of S- and N-containing compounds, like glutathione and other peptides, as a source of reductant in many oxidation reactions, and acting against heavy metals toxicity, or lipid and polyphenol oxidation as ROS-scavenger is today very well established. In that respect, the aim of the present study is to introduce an original analytical tool for the direct determination of the available nucleophilic compounds in white wine under acidic pH conditions. One step derivatization of nucleophiles has been realized directly in wines using 4-met…
