Naming organic wines in French and German A Frame Semantics analysis
2019
International audience; [Context]Naming a product is giving it an identity (Lobin, 2016); when it comes to wines it is offering them, the possibility to be easily discriminated and to catch the clients’ attention. This contribution aims at analyzing the naming of organic wines in two countries: France and Germany. If naming generic wines has already been investigated especially from a lexical point of view (Herling, 2015), wine names from the organic wine industry have for the time being been left aside. In the meantime, previous studies based on authentic materials have underlined, since Lehrer, 1975, some specificities in the wine language like resorting to prototypes (Gautier & Bach, 201…
(De)terminologisation processes in wine tasting notes : How expressive are canonical and non-canonical hedonic markers?
2022
Following the proposal of Gautier (2018), an important part of the “terminology” of wine tasting notes is made up by hedonic markers that cannot always be treated as terms – in the traditional meaning of technical/specialised terms – as they lack a consensual definition acknowledged by field experts. The main challenges of such markers concern at least the following three dimensions: (i) they are directly linked to the gustative experience of the taster/speaker and his/her experiential memory; (ii) they are also linked to the field knowledge and the degree of expertise of the taster/speaker – be it a “true” knowledge or his/her ability to imitate expert discourse and (iii) they are mostly s…
Effect of Nitrogen Fertilization on the Quality of Swiss Chard at Harvest and during Storage as Minimally Processed Produce
2014
The effects of different levels of nitrogen fertilization (0–50–100–150–200 kg/ha), minimal processing and cold storage (14 days at 4C) on yield and quality of fresh-cut Swiss chard (Beta vulgaris L. var. cicla L.) were evaluated. Increasing the level of nitrogen fertilization over 100 kg N/ha, plants had a higher fresh weight, reduced their dry matter content and resulted taller and leafier. Total and marketable yield increased linearly with increasing nitrogen level. Both nitrate and ascorbic acid content at harvest increased with increasing nitrogen supply. Nitrogen fertilization negatively affected the yield of minimal processing. No effect on appearance and quality loss during cold sto…
Full‐thickness tissue engineered oral mucosa for genitourinary reconstruction: A comparison of different collagen‐based biodegradable membranes
2020
Tissue engineering is a method of growing importance regarding clinical application in the genitourinary region. One of the key factors in successfully development of an artificially tissue engineered mucosa equivalent (TEOM) is the optimal choice of the scaffold. Collagen scaffolds are regarded as gold standard in dermal tissue reconstruction. Four distinct collagen scaffolds were evaluated for the ability to support the development of an organotypical tissue architecture. TEOMs were established by seeding cocultures of primary oral epithelial cells and fibroblasts on four distinct collagen membranes. Cell viability was assessed by MTT-assay. The 3D architecture and functionality of the ti…
Increasing the levels of 2-phenylethyl acetate in wine through the use of a mixed culture of Hanseniaspora osmophila and Saccharomyces cerevisiae
2009
The impact of mixed cultures of Hanseniaspora osmophila and Saccharomyces cerevisiae with different initial yeast ratios on wine composition has been examined. The mixed culture significantly affected sugar consumption, the main enological parameters and ester concentrations, with the exception of glycerol, isoamyl acetate and diethyl succinate levels. Remarkably, in wines obtained with mixed cultures the concentration of 2-phenylethyl acetate was approximately 3- to 9-fold greater than that produced by S. cerevisiae pure culture. Moreover sensory evaluation revealed a stronger fruity character in wines fermented with mixed cultures than in control wines. Independently of the mixed culture …
A multi-phase multi-objective genome-scale model shows diverse redox balance strategies in yeasts
2021
Yeasts constitute over 1500 species with great potential for biotechnology. Still, the yeastSaccharomyces cerevisiaedominates industrial applications and many alternative physiological capabilities of lesser-known yeasts are not being fully exploited. While comparative genomics receives substantial attention, little is known about yeasts’ metabolic specificity in batch cultures. Here we propose a multi-phase multi-objective dynamic genome-scale model of yeast batch cultures that describes the uptake of carbon and nitrogen sources and the production of primary and secondary metabolites. The model integrates a specific metabolic reconstruction, based on the consensus Yeast8, and a kinetic mod…
Entrepreneurial competencies and competitiveness: an empirical analysis in the small wine companies in Sicily
2012
Several approaches in the economical literature have been suggested for the competitiveness analysis which are different depending on the aim of the analysis, on the level of the survey and on the analysis space-time structure (Buckley et al., 1988; Banterle, Carraresi, 2006). Regarding to the competitiveness of the company, a lot of studies show that the availability of tangible resources does not stand by itself a successful condition, however, it must be seen as a constellation of resources, capacity and expertise. These studies suggest the key role of competencies, considered as a source of strategic advantage, and whose identification and evaluation is a central issue of the survival a…
El mercado mundial de vino y la competitividad de los países del Hemisferio Sur, 1961-2010
2014
<p><strong></strong>El mercado mundial del vino ha sufrido cambios intensos en las últimas décadas tras un fuerte incremento de la competitividad de los países exportadores del hemisferio sur. Su dinamismo y el aumento de la demanda de los nuevos países consumidores han acelerado el proceso de globalización del vino. En este contexto, analizamos la competencia mundial y los principales cambios en el comercio global de vinos desde 1961 hasta 2010. El artículo muestra la distribución relativa de las exportaciones en el Viejo y el Nuevo Mundo y examina la ventaja comparativa del comercio exterior a través del índice de ventaja comparativa revelada (VCR). Concluye mostrando la…
Grapevine and wine metabolomics-based guidelines for fair data and metadata management
2021
In the era of big and omics data, good organization, management, and description of experimental data are crucial for achieving high-quality datasets. This, in turn, is essential for the export of robust results, to publish reliable papers, make data more easily available, and unlock the huge potential of data reuse. Lately, more and more journals now require authors to share data and metadata according to the FAIR (Findable, Accessible, Interoperable, Reusable) principles. This work aims to provide a step-by-step guideline for the FAIR data and metadata management specific to grapevine and wine science. In detail, the guidelines include recommendations for the organization of data and meta…
Optical system for automatic color monitoring in heterogeneous media during vinification processes
2019
Abstract Wine is one of the most important food products worldwide. However, the application of technologies to the winemaking process can improve. An RGBC optical sensor, used to measure color intensity and shade, was developed and tested in real environments. It is able to measure samples without filtering by offering the color intensity and shade of a filtered sample. Color intensity can be measured within the range of 1.5 and 9.5 color points with an approximate 3% error. The model for shade can be applied to red wines with an approximate 1% error. It can operate directly in cellars under real operating conditions. It avoids collecting samples, and filtering and measuring in a spectroph…
