摘要: Alpha-acids in hop extracts are isomerized by forming a salt of the alpha-acids in a water immiscible organic solvent with a base selected from oxides, hydroxides and carbonates of calcium, magnesium, strontium, barium and zinc and heating the alpha-acid salt in the solvent to form iso-alpha-acid salts. Iso-alpha-acids may be recovered in crude form and used for bittering beer.

摘要: The present invention provides a method for reducing the tendency of beer to gush by incorporating in the beer 1 to 20 percent based on the weight of iso- Alpha -acids in the finished beer of an unsaturated fatty acid having from 10 to 20 carbon atoms. The invention includes hop extracts containing said unsaturated fatty acid and also includes methods of making said extracts.
