Abstract

Dans un premier aspect, la présente invention concerne un procédé permettant de former un revêtement ou une couche de diffusion sur un substrat (p. ex. bouchon) destiné à entrer en contact avec un produit alimentaire ou une boisson. Ce revêtement ou cette couche de diffusion empêchent ou inhibent le passage (p. ex. du bouchon dans une boisson alcoolisée) de composés vecteurs de goûts ou d'odeurs (habituellement désignés par « goût de bouchon »). Ce procédé consiste à appliquer à la surface de ce substrat une quantité efficace de polymère réactif, composé d'un matériau polymère comprenant une première série de groupes fonctionnels qui réagissent avec au moins un composé vecteur de goût ou d'odeur, et une seconde série de groupes fonctionnels (qui peuvent être identiques aux premiers ou différents de ceux-ci) qui réagissent avec ce substrat. Un second aspect de l'invention concerne un substrat recouvert d'un revêtement, en particulier un bouchon naturel ou synthétique recouvert d'un revêtement, produit selon le procédé ci-dessus.
