Zhang, Ming-jun published the artcileComparison of LLE and SPME Methods for Screening the Aroma Compounds in Rum, Application of Ethyl octanoate, the main research area is liquid extraction solid phase microextraction rum aroma compound screening.
Liquid-liquid extraction (LLE) and solid-phase microextraction (SPME) methods were applied to extract the aroma compounds of rum. Aroma compounds were separated and analyzed with gas chromatog.-mass spectrometry of DB-WAXetr capillary columns. One hundred and twelve compounds, including alcs., esters, aldehydes, ketones, phenols, acids, and other compounds, were identified by two extraction methods. Among them, 88 and 74 compounds were identified by SPME and LLE, resp. SPME and LLE methods were suitable for the qual. and semi-quant. anal. of rum, resp. Principal component anal. results showed that the first principal component (PC1) and the second principal component (PC2) explained 80.9% of the difference in variable samples (PC1 = 52.7%, PC2 = 28.2%), which can represent the variable characteristics of the samples. The extraction effects of LLE and SPME on the aroma compounds of rum obviously differed, however, the aroma compounds obtained by the two extraction methods can complement each other.
