The present invention is related to a complexating system comprising a tannin immobilised on a solid support by means of a bifunctional spacer which is covalently bound from one hand to said solid support by a first function and from the other hand to said tannin by a second function, wherein the tannin is a naturally occurring tannin and exhibits at least six hydroxyl groups. Said complexating system can be used in particular for chelating metals and proteins, as an antioxidant, as a radical scavenger or as an antibacterial. More specifically, applications can be found in the clarification and stabilisation of beverages, the treatment of textiles, or the separation and/or purification of proteins and/or metals.
La présente invention se rapporte à un système de complexation comprenant un tanin immobilisé sur un support solide au moyen d'un séparateur bifonctionnel, lequel est lié par covalence audit support solide par une première fonction et audit tanin par une seconde fonction, le tanin étant un tanin d'origine naturelle et présentant au moins six groupes hydroxyles. Ledit système de complexation peut être utilisé notamment pour chélater des métaux et des protéines, en tant qu'antioxydant, fixateur de radicaux ou antibactérien. Plus précisément, ce système trouve une application dans la clarification et la stabilisation de boissons, dans le traitement de textiles, ou dans la séparation et/ou la purification de protéines et/ou de métaux.
