Resumo(s): | Knowledge of composition of beverages volatile fraction is essential for understanding their sensory attributes. Analysis of volatile compounds predominantly resorts to gas chromatography coupled with mass spectrometry (GCMS). Often a previous concentration step is required to quantify compounds found at low concentrations. This work presents a liquidliquid microextraction method combined with GCMS (LLME/GCMS) for the analysis of compounds in fermented beverages and spirits. The method was validated for a set of compounds typically found in fermented beverages comprising alcohols, esters, volatile phenols, and monoterpenic alcohols. The key requirements for validity were observed, namely linearity, sensitivity in the studied range, accuracy, and precision within the required parameters. Robustness of the method was also evaluated with satisfactory results. Thus, the proposed LLME/GCMS method may be a useful tool for the analysis of several fermented beverages, which is easily implementable in a laboratory equipped with a GCMS. |
