摘要： The present invention is related to a particulate insoluble product containing a polyphenol such as tannins that is covalently bound to a polymeric backbone by means of a bifunctional spacer, of which one functionality may react with said polyphenol, and the other is a silicium based group, such as to form an immobilised polyphenol.
The product thus obtained can be used as a complexating agent for metals and proteins, as an antioxidant, as a radical scavenger or as an antibacterial.
