  • Toxic phenolic compound removal by selective binding of phenolic compounds using smart polymers
    Patent number: 8927042
    Abstract: The present invention corresponds to a method for the removal of unwanted toxic phenolic compounds such as a pesticide from foodstuffs, more particularly beverages. The method comprising contacting a selected polymer with the foodstuff. In a particular embodiment, the polymers are selected among polyaniline (PANI), polyaniline emeraldine base (PANI-EB) and polyaniline emeraldine salt (PANI-ES) polymers, or the polymers are selected among polyamidoamine (PAMAM) dendrimers functionalized with polyaniline (PANI), polyaniline emeraldine base (PANI-EB) and polyaniline emeraldine salt (PANI-ES) polymers.
