Natufine is a purified fining agent consisting of Collagen produced from the traditional source, predominantly swim bladders of fish. Natufine is supplied as an easy to dissolve powder yet still maintains the properties of finings prepared over a long period of time. Natufine speeds up and improves beer clarification by accelerating the sedimentation of yeast & other insoluble material into a compact layer at the bottom of the storage tank. At the pH of beer a positive charge of Natufine neutralizes the negative charge of the yeast cells, destroying the mutual repulsion that keeps the cells in suspension and promoting rapid flocculation that settles the yeast cells quickly to the bottom of the tank.

  • Natufine substantially reduces setting time of yeast and reduces time in storage
  • Natufine dramatically increases the quantity of yeast and proteinaceous solids deposited out during storage, leaving beer so clear that the filteration process can be reduced to single pass
  • Tanks bottoms are better compacted giving sharp interface between clear beer and sediment resulting in a better recovery of beer
  • Use of Natufine results in significant increase in filter throughout with savings of filtrations aid, time and labor
  • Natufine prepared under ideal conditions is ready to use after only half-hour of mixing
  • Metabisulphite is incorporated into Natufine powder to give automatic microbiological stabilization & also protects beer from oxidation


Natufine being added as a 0.5% solution in cold water (approx 4-5 C) and give retention of 30 minutes. Natufine solution must be added to beer entering the storage period in a manner which ensures effective mixing. Metering finings into the beer stream throughout the filling of the primary storage tanks, or addition from a stainless steel cask under CO pressure via sample point throughout filling have both been found to give 2 highly satisfactory results.
