Analysis of free fatty acids in beer: Comparison of solid-phase extraction, solid phase microextraction, and stir bar sorptive extraction
Original language description
SPE, SPME and SBSE followed by solvent back extraction have been used for the extraction of free fatty acids (caproic - linolenic acids) from beer. Subsequent gas chromatographic analyses with flame ionization detection were used for the determination ofthese compounds. Medium-chain fatty acids (caproic-lauric acid) were determined as free acids, and long-chain fatty acids (myristic-linolenic acids) were determined as methyl esters after methylation by BF3-methanol 14%. Linearity, recovery, and repeatability of all methods have been determined and compared with the SPE method used as a reference. All three procedures provide similar working parameters characterized by high repeatability (2.3-16.3%) and good linearity (correlation coefficient ranging from 0.9919 to 0.9999). Results of beer analyses obtained by using these three methods were highly correlated.
