Le goût de la récolte. Cueillir son vin du XIVe siècle à nos jours
2011
National audience; S'imposant comme modalité officielle pour encadrer la récolte, la pratique du ban n'a été supprimée que très récemment en Bourgogne. Jadis acte de l'autorité seigneuriale, le ban est associé à une pratique documentée dans les archives depuis les années 1370. Il est ainsi possible d'étudier de façon continue les modalités de la vendange depuis cette époque. Cela signifie aussi, d'un point de vue social, qu'une décision collective préside à la récolte des raisins sur le temps long, récolte qui engage la qualité et les caractères du vin qui sera produit, sachant que jusqu'au XVIIIe siècle les réflexions précieuses sur la vinification ont un assez faible écho. Dans les source…
Looking for ancient wine as gift for the Prince of Lavau (5th c. BC)
2017
International audience; The excavations at Lavau brought to light a large monumental necropolis with a central burial mound overlying an undisturbed chieftain’s grave from the end of the Early Iron Age or the beginning of the Late Iron Age. In the funerary chamber rich grave furniture accompanied the dead: a bronze cauldron containing serving and drinking vessels of ceramic, silver, and bronze, two bronze plates, and a cist. As there were visible deposits present on the inner surface of the cauldron, a series of samples were taken from different parts of the cauldron and the locally made oenochoe. Using a double-step methodology of extraction and structural analysis by GC-MS, the main bioma…
An exploratory study to investigate emotion elicited by immersive ambiances
2011
Food behaviour is modulated by the eating situation and environment. In a previous study, we investigated drink choices according to the ambiance by developing an immersive approach based on the concept of “having a drink in a bar”. Two bars (Modern vs. Traditional ambiance) were settled with a few piece of furniture (counter, tables and bar stools) made in raw wood for the Traditional bar and in blue retro-lighted translucent plastic for the Modern bar. A video-clip was projected on one wall: Red moving shapes associated to a “far west” music in the Traditional bar, and Blue moving bubbles associated to an “electro” music in the Modern bar. In each bar, 100 participants were asked which be…
Dissociation-constants of metat-ion-complexes with alkaline phosphatase from pig kidney.
1976
Using metal-ion buffers it was possible to remove Zn2+, Mg2+ and Mn2+ ions of pig kidney alkaline phosphatase reversibly. The dissociation constants obtained are KEMg: 4 X 10(-7) M, KEMn: 4 X 10(-8) M and KEZn: 8 X 10(-13) M (22 degrees C, pH: 9.6, mu: 0.07).
Development of molecular approaches for direct detection and quantification of wine-related microorganisms
2018
En esta tesis doctoral se han desarrollado procedimientos para la detección y cuantificación de levaduras y bacterias acéticas totales y, en concreto, de las especies más importantes en la vinificación como Saccharomyces cerevisiae, Brettanomyces bruxellensis, Zygosaccharomyces bailii, L. plantarum, y O. oeni. Las estrategias que se han utilizado para el desarrollo de nuevos métodos se centran fundamentalmente en la supresión del paso de extracción previa de ADN y de los procedimientos de eliminación de inhibidores de la reacción de PCR presentes en las muestras. Para llevar a cabo este objetivo general, se establecieron los siguientes objetivos específicos; 1, desarrollo de un método de qP…
Comparative genomics among Saccharomyces cerevisiae x Saccharomyces kudriavzevii natural hybrid strains isolated from wine and beer reveals different…
2012
Abstract Background Interspecific hybrids between S. cerevisiae × S. kudriavzevii have frequently been detected in wine and beer fermentations. Significant physiological differences among parental and hybrid strains under different stress conditions have been evidenced. In this study, we used comparative genome hybridization analysis to evaluate the genome composition of different S. cerevisiae × S. kudriavzevii natural hybrids isolated from wine and beer fermentations to infer their evolutionary origins and to figure out the potential role of common S. kudriavzevii gene fraction present in these hybrids. Results Comparative genomic hybridization (CGH) and ploidy analyses carried out in thi…
Effect of consumers’ origin on perceived sensory quality, liking and liking drivers: A cross-cultural study on European cheeses
2021
Abstract We aim at studying consumers’ Perceived Sensory Quality (PSQ) concept. We manipulated a priori both familiarity (contrast local vs. foreign cheeses) and quality level (contrast PDO or traditional cheeses vs. their non-PDO and/or industrial counterpart). The study was run in four European countries. Thus, eight cheeses (one PDO or traditional cheese and one non-PDO cheese from each of the four European countries) were assessed by a total of 438 consumers (from 100 to 120 consumers from each region) in terms of PSQ and liking. The cheeses were also described by a trained panel. PSQ depended on both consumers’ and cheeses’ origin. The main finding is that in the three countries with P…
Glycerosomes:investigation of role of 1,2-dimyristoyl-sn-glycero-3-phosphatidycholine (DMPC) on the assembling and skin delivery performances
2017
Glycerosomes were formulated using 1,2-dimyristoyl-sn-glycero-3-phosphatidycholine (DMPC), diclofenac sodium salt and 10, 20 or 30% glycerol in the water phase, while corresponding liposomes were prepared with the same amount of DMPC and diclofenac, without glycerol. The aim of the present work was to evaluate the effect of the used phospholipid on vesicle features and ability to favour diclofenac skin deposition by comparing these results with those found in previous works performed using hydrogenated soy phosphatidylcholine (P90H) and dipalmitoylphosphatidylcholine (DPPC). Liposomes and glycerosomes were multilamellar, liposomes being smaller (72±6nm). Interactions among glycerol, phospho…
Diuron mobility through vineyard soils contaminated with copper
2005
International audience; The herbicide diuron is frequently applied to vineyard soils in Burgundy, along with repeated treatments with Bordeaux mixture (a blend of copper sulfate and calcium hydroxide) that result in elevated copper concentrations. Cu could in principle affect the fate and transport of diuron or its metabolites in the soil either directly by complexation or indirectly by altering the populations or activity of microbes involved in their degradation. To assess the effect of high Cu concentrations on diuron transport, an experiment was designed with ten undisturbed columns of calcareous and acidic soils contaminated with 17–509 mg kg−1 total Cu (field-applied). Grass was plant…
Wines and spirits in the comprehensive and economic trade agreement (CETA): an analysis
2021
Il saggio analizza l’accordo commerciale globale ed economico (CETA) tra l’Unione Europea e il Canada limitatamente al commercio di vino e spiriti. L’Accordo, avente l’obiettivo di rilanciare il commercio e aumentare la crescita del mercato e l’occupazione, nonostante sia stato ratificato dalla maggioranza dei Paesi dell’Unione, non è ancora stato ratificato dall’Italia. Si guarda, quindi, in modo critico alle modi che che il CETA ha apportato all’accordo CE – Canada del 2003 volto a creare condizioni più favorevoli per lo sviluppo armonioso del commercio di vino e bevande spiritose sulla base dei principi di uguaglianza e vantaggio reciproco. The paper analyzed the Annex dedicated to win…
