A process for reducing acetaldehyde concentration in beverages contained in polyester-based packaging, wherein oxygen permeation into the container is reduced or eliminated. The polyester contains an oxidation catalyst active for the oxidation of acetaldehyde to acetic acid. A composition comprising a polyester and said oxidation catalyst. A polyester-based container comprising said oxidation catalyst, and a bottled beverage having a polyester-based container comprising an oxidation catalyst active for the oxidation of acetaldehyde to acetic acid.
L'invention concerne un procédé pour réduire la teneur en acétaldehyde des boissons conditionnés dans des emballages à base de polyester qui réduisent ou interdisent la perméation de l'oxygène dans le récipient. Le polyester contient un catalyseur d'oxydation fonctionnant de manière à oxyder l'acétaldéhyde en acide acétique. Une composition comprend un polyester et ledit catalyseur d'oxydation. Un récipient à base de polyester contient ce catalyseur d'oxydation et une boisson en bouteilles, le récipient à base de polyester contenant un catalyseur d'oxydation actif fonctionnant de manière à oxyder l'acétaldéhyde en acide acétique.
