Abstract
A method for sequestering methionine molecules contained in a liquid medium, comprising contacting this liquid medium with a solid polymer material comprising monomer units based on porphyrin containing copper. This method is particularly applicable to the processing of a liquid food product, such as wine, with a view to decreasing the risk of a lightstruck taste occurring.
Claims20
A method for sequestering methionine molecules contained in a liquid medium, comprising contacting said liquid medium with a solid polymer material comprising monomer units based on porphyrin containing copper.
A porous solid polymer material obtainable by a synthesis method comprising the steps of:
- a/ preparing a porphyrin derivative of formula (VI):
- b/ polycondensing said porphyrin derivative of formula (VI) with a compound of formula (VII):
- wherein:
- R10 and R13 each represent a carbonitrile group —CN,
- R11, R12, R14 and R15, identical or different, each represent a halogen atom,
- in the presence of a compound of formula (VIII):
- wherein:
- R16 represents a hydroxyl, primary or secondary amine or thiol group,
- R17 and R13, identical or different, each represent a hydrogen atom or a group selected from the group consisting of a sulfonate ion or a salt thereof, a carboxylate ion or a salt thereof, an ammonium ion or a salt thereof, and a boronic acid group, and
- c/ complexing the porphyrin rings of the polymer obtained in step b/ with copper.
