Abstract: Beverages such as juices, vinegars, beers and wines are clarified and rendered haze-free by contacting the beverages with water-insoluble, water-swellable, crosslinked N-vinyllactam or Nalkyl-N-vinylamide polymers in the form of porous granules or beads. The granules or beads when spent are regenerated by an aqueous alkaline treatment.
