Determination of iso-compounds in wort and beer.Peer-reviewed article

J. ŠROGL, J. DYRHONOVÁ, H. JAROŠOVÁ

If either the Klopper or Moltke-Meilgaard method is applied to determine iso-compounds in wort or beer, stable emulsion may appear which are very difficult to remove. The author recommends a new method preventing formation of emulsions by using surface active agents. Very efficient in this respect are dimethyllaurilbenzylammonium bromide [Ajatin] and cetyltrimethylammonium bromide. Very small amounts of the two compounds added before extraction  prevent formation of emulsions.
