Effect of different yeast-derived products on a red wine polyphenolic composition: influence of the wine age

Autor: Julie NGUELA, Nathalie Sieczkowski, Aude Vernhet

Publikováno v: OENO One, Vol 58, Iss 3 (2024)

The name “yeast-derived products” (YDPs) refers to different preparations obtained from yeast cells through various processes. These YDPs have different characteristics and applications in oenology, one being the improvement of the sensory proper

Exploring the role of grape cell wall and yeast polysaccharides in the extraction and stabilisation of anthocyanins and tannins in red wines

Autor: Jean-Claude Boulet, Aude Vernhet, Céline Poncet-Legrand, Véronique Cheynier, Thierry Doco

Publikováno v: OENO One, Vol 58, Iss 1 (2024)

This paper explores the relationships between polysaccharides/oligosaccharides and anthocyanins/tannins from berry to wine. It is in the form of a review in which the literature has been considered in the light of the following model: in order to rem

Diffusion of phenolic compounds during a model maceration in winemaking: role of flesh and seeds

Autor: Elissa Abi‐Habib, Aude Vernhet, Stéphanie Roi, Stéphanie Carrillo, Fredéric Veran, Marie‐Agnès Ducasse, Céline Poncet‐Legrand

Publikováno v: Journal of the Science of Food and Agriculture. 103:2004-2013

During red winemaking, diffusion of phenolic compounds from the grape berry cells into the liquid phase occurs simultaneously with the adsorption of the same compounds onto the pulp. In previous studies, we quantified the proportions of polyphenols d

Characterization of suspended solids in thermo-treated red musts

Autor: Aude Vernhet, Magali Bes, Delphine Bouissou, Stéphanie Carrillo, Jean-Marc Brillouet

Publikováno v: OENO One, Vol 50, Iss 1, Pp 9-21 (2016)

Aims: Thermo-treatment of grapes, followed by pressing and fermentation in liquid phase, is a growing practice in red winemaking to obtain light and fruity wines. Must clarification before fermentation, a key step to get the expected wine profile, is

Concentrations of anthocyanins and tannins after extraction from berries in wines and from skin macerations in model solutions have been studied for two grape varieties, two maturation levels and two vintages berries. Characterization of the cell wal
