Abstract

Deep Eutectic Solvents (DESs) represent an emerging class of biorenewable solvents usuallyprepared by mixing two or three safe and inexpensive components able to form an eutecticmixture with a melting point further below that of the individual components. Due to theirlow toxicity and biodegradability they are progressively replacing conventional volatileorganic compounds (VOCs) in several fields of science. An increasing number of studies, inparticular, have reported the feasibility of extracting bioactive compounds from naturalsources (Ruesgas-Ramón et al., JAFC, 2017, 65, 3591). Our efforts of late have focused onthe use of these media in the extraction of contaminants, such as mycotoxins, from foodmatrices.MethodsAn analytical method for the determination of the mycotoxin Ochratoxin A (OTA) in wheatand some processing products has been developed and validated using choline chloride(ChCl)-based solvent as privileged and biodegradable extraction media (Piemontese et al.Molecules, 2017, 22, 121). We have then implemented the method to include a largerscreening on many solid food matrices using several DESs with different physical-chemicalcharacteristics.ResultsUsing the ChCl/urea (1:2)/water (+ 40% w/w) mixture, the analytical performances, in termof recovery and repeatability for durum wheat, bread crumbs, and biscuits, proved to becomparable to those obtained with conventional and hazardous VOCs, which are typicallyemployed according to the standard and official methods. The tunability of DESs ispromising to extend the use of the validated method to other food commodities. Preliminaryresults obtained with the ChCl/lactic acid (1:2)/water (+25% w/w) mixture have revealedgood extraction performances on a wide number of solid matrices.
