METHOD FOR THE REGENERATION OF SPECIAL FILTER AIDS FOR THE STABILIZATION OF BEVERAGES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18288047 titled 'METHOD FOR THE REGENERATION OF SPECIAL FILTER AIDS FOR THE STABILIZATION OF BEVERAGES

The present invention involves a method for regenerating special filter aids, specifically crosslinked copolymers containing N-vinylimidazole and N-vinylpyrrolidone as monomeric units.

  • The copolymer is rinsed with water, then brought into contact with an aqueous solution of at least one acid, followed by another water rinse to neutralize the copolymer.
  • Subsequently, the copolymer is brought into contact with an aqueous solution of at least one base, and then rinsed with water or an aqueous solution of at least one acid to neutralize it.
  • The regenerated copolymer produced by this method can be used as a filter aid for stabilizing beverages.
