  "description": "<p>An unprecedented, environmentally friendly, and faster method for the determination of<br>\nOchratoxin A (OTA) (a mycotoxin produced by several species of Aspergillus and Penicillium and<br>\nlargely widespread in nature, in wheat and derived products) has, for the first time, been set up and<br>\nvalidated using choline chloride (ChCl)-based deep eutectic solvents (DESs) (e.g., ChCl/glycerol<br>\n(1:2) and ChCl/ urea (1:2) up to 40% (w/w) water) as privileged, green, and biodegradable extraction<br>\nsolvents. This also reduces worker exposure to toxic chemicals. Results are comparable to those<br>\nobtained using conventional, hazardous and volatile organic solvents (VOCs) typical of the standard<br>\nand official methods. OTA recovery from spiked durum wheat samples, in particular, was to up to<br>\n89% versus 93% using the traditional acetonitrile-water mixture with a repeatability of the results<br>\n(RSDr) of 7%. Compatibility of the DES mixture with the antibodies of the immunoaffinity column<br>\nwas excellent as it was able to retain up to 96% of the OTA. Recovery and repeatability for durum<br>\nwheat, bread crumbs, and biscuits proved to be within the specifications required by the current<br>\nEuropean Commission (EC) regulation. Good results in terms of accuracy and precision were<br>\nachieved with mean recoveries between 70% (durum wheat) and 88% (bread crumbs) and an RSDr<br>\nbetween 2% (biscuits) and 7% (bread).</p>",
