Epoxy-polymerized tannin/inorganic oxide composite particles are obtained by polymerizing the tannin with a polyepoxy cross-linking agent in situ on inorganic oxide particles. The compositions of the invention are capable of achieving the performance of tannin in beverage treatment applications without tannin's associated filtration disadvantages.
Selon l'invention, on obtient des particules de composites tanninpolymérisé par époxy/oxyde inorganique par polymérisation du tannin avec un agent de réticulation polyépoxy in situ, sur des particules d'oxyde inorganique. Les compositions selon l'invention permettent d'obtenir, lors du traitement de boissons, les mêmes résultats que ceux obtenus avec le tannin mais sans avoir les inconvénients résultant du fait que le tannin doit être filtré.
