METHODS FOR THE ANALYSIS OF C4 TO C10 FATTY ACIDS IN BEER, WORT AND CARBOHYDRATE SYRUPS

Abstract
Methods have been developed for the analysis of C4 to C10 fatty acids in beer, wort and carbohydrate syrups. The methods are based on the adsorption of the aqueous samples on to solid supports followed by removal of the fatty acids with organic solvents. The methods are suitable for routine batchwise analysis of fatty acids and the reproducibility of the analysis and recoveries of the acids are generally good. Problems often encountered with analysis of C4 to C10 fatty acids and possible solutions are also discussed.
