Comparison of Three Solid Phase Microextraction Fibers for Aromatic Compounds in Muskmelon Juice

Abstract:

The aromatic compounds in muskmelon juice were extracted by three solid phase microextraction (SPME) fibers, such as Carboxen^TM/PDMS, DVB/CAR/PDMS and PDMS/DVB, respectively, and analyzed by GC-MS method. The results showed that the majority aromatic compounds were esters with a little of aldehydes and alcohols. The aromatic component relative content was 91.55%, and the relative content of main aromatic components was 63.01% extracted by Carboxen^TM/PDMS fiber. Althought the aromatic components extracted by DVB/CAR/PDMS fiber were completely, the aromatic component relative content, relative content of main aromatic components and total peak areas were lower than those by Carboxen^TM/PDMS fiber. The aromatic components extracted by PDMS/DVB fiber had little kinds with low relative content. It suggested that the Carboxen^TM/PDMS fiber was the most suitable for extracting amomatic compounds in muskmelon juice.
