Description
Summary:A multiphase electric field–assisted extraction approach was evaluated and optimised to extract and concentrate caprylic acid from cider and mead samples. The system was composed by a solid support wetted with an electrolyte solution, a few microlitres of a mixture of organic solvents (acceptor phase) and the sample. This new device was applied to extract free caprylic acid in cider and mead samples. An optimal condition was found by a Box-Behnken design: electric potential of 200 V, extraction time of 15 min and electrolyte solution concentration of 150 mg L −1 of NaOH and 150 mg L −1 of NH 4 OH (1:1 v/v). After the extraction procedure, caprylic acid was determined by UHPLC-MS/MS (in negative mode, ESI −). The performance of the method was measured by linearity and matrix effect, both evaluated by statistical tests. Linearity was demonstrated in the range of 0.1–5.0 mg L −1 ( R 2  > 0.98), chromatograms were free of interferent peaks, extracts were clean, and the consumption of solvent was much lower than those observed for conventional liquid–liquid extraction. Those promising results, added to the easy assembly and low cost of the development of the system, make it an interesting approach for sample preparation of fatty acids in fermented beverages.
