“…This methodology is well known and commonly used for the sample preparation for emerging toxic substance (i.e. pesticides, 16 polycyclic aromatic hydrocarbons, 17,18 3-monochloropropane-1,2diol 19 or peruorooalkyl substances 20,21 ) determination. However, to the best of our knowledge, the possibility of QuEChERS application for sample preparation in the AA analysis has still remained unexplored.…”

This paper reports rapid and simple sample preparation method development for acrylamide (AA) determination in cocoa powder through conversion to N, O-bis(trimethylsilyl)acrylamide. AA level was quantified in the relation to a acrylamide-d 3 internal standard using gas chromatography coupled with ion-trap mass spectrometry in the single ion monitoring mode (GC-SIM-MS).Analytical procedure consisted of the extraction with organic solvent (acetonitrile with/without hexane addition), extract purification by dispersive solid-phase extraction (d-SPE) using various sorbents (SAX, C18, ENV, Florisil) apart from PSA sorbent, followed by derivatisation with N,OBis (trimethylsilyl) trifluoroacetamide (BSTFA) and finally with chromatographic analysis (GC-SIM-MS) using deuterated internal standard. Nine variants of the method were tested. The usefulness of the method has been verified based on the recovery ratio of acrylamide. The obtained results showed that the best recovery of 98.2% with RSD lower than 10% was obtained using a combination of sorbents PSA and C 18 with the addition of hexane in the initial stage of the extraction. The developed method has been successfully applied to determination of acrylamide in 9 cocoa powder and 30 chocolate (dark, milk and white) samples purchased at Polish supermarket.The results of AA content ranged from 54.2 to 168.0 µg kg -1 and from 25.5 to 256.1 µg kg -1 for cocoa powder and chocolate, respectively. The obtained results were in good agreement with literature reports.

“…In this step, C18, silica, graphitized carbon, or solid-phase [44]. Nevertheless, in recent years, the QuEChERS method has been extended and successfully employed in the determination of other contaminants such as PAHs, acrylamide, or chloropropanols [45][46][47]. Application of ENV (styrene-divinylbenzene) SPE Bulk Sorbent in the sample treatment step for the determination of PFAAs has been successfully used to carry out rapid puri cation of di erent food matrices [48][49][50].…”

Per- and polyfluoroalkyl substances (PFASs) are widely distributed across the world and are expected to be of concern to human health and the environment. The review focuses on perfluoroalkyl acids (PFAAs) and, in particular, on the most frequently discussed perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkane sulfonic acids (PFSAs). In this study, some basic information concerning PFASs is reviewed, focusing mainly on PFAAs (perfluoroalkyl acids). We have made efforts to systemize their division into groups according to chemical structure, describe their basic physicochemical properties, characterize production technologies, and determine potential human exposure routes with particular reference to oral exposure. A variety of possible toxicological effects to human health are also discussed. In response to increasing public concern about the toxicity of PFAAs, an evaluation of dietary intake has been undertaken for two of the most commonly known PFAAs: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). As summarized in this study, PFAAs levels need further assessment due to the science-based TWI standards laid down by the EFSA’s CONTAM Panel regarding the risk to human health posed by the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food (tolerable weekly intakes of PFOA and PFOS set up to 6 ng·kg−1·bw·week−1 and 13 ng·kg−1·bw·week−1, respectively). Current legislation, relevant legislation on PFAAs levels in food, and the most popular methods of analysis in food matrices are described.

In recent years, food safety issue has become one of the focuses of global concerns. Chromatography as the most common method has been applied to detecting harmful substances in food widely. However, chromatographic methods used in the detection of analytes with the characteristic of low molecular weight, high polarity, low volatility, thermal instability, less chromophore will encounter some problems such as low detection response and low retention time. While, derivatization is a common means to solve these problems. In this paper, we mainly introduced derivative reagents and derivatization methods in sample preparation. The applications of derivatization techniques in chromatographic analysis of mycotoxins, illegal additives, pesticide and veterinary drug residues, and so on in food samples were reviewed.
