“…The amount of sodium chloride applied in the extraction process is another important factor affecting extraction recovery . To evaluate the effect of addition of sodium chloride on the extraction recoveries, different additions of sodium chloride were analyzed within the range of 0–300 mg.…”

“…This could be explained by considerations of salting‐out effects and salting‐in effects . Salting‐out enhances the transfer of analytes into organic extraction solvent and therefore increases the amount extracted, however, salting‐in could lead to the dissolution of the analytes in water thus decreasing the amount extracted and reducing the extraction efficiency . Appropriate addition could maximize the dissolution of pyrethroids into the extraction solvent and minimize the dissolution of extraction solvent in water: however, extraction recovery decreased with continuing addition of sodium chloride, which may because the continuing addition of sodium chloride increases the viscosity of the sample solution, possibly restraining the transfer of the analytes to the extraction solvent.…”

In this research, a novel method—namely vortex‐assisted emulsification microextraction—was introduced for the determination of pyrethroids (flucythrinate, beta‐cypermethrin, and fenvalerate) in mushrooms (Agaricus bisporus, Lentinula edodes, Auricularia auricular, and Flammulina velutiper). A green solvent 1‐dodecanol was used as the extraction solvent. The low freezing point makes 1‐dodecanol easy to solidify and separate after retention in an ice bath. To avoid the use of dispersion solvents, vortex agitation was applied instead to increase the contact area between extraction solvent and samples. The type and volume of extraction solvent, time of extraction, and addition of sodium chloride were optimized. Under optimal conditions, linear responses were obtained within 1–100 μg/g (R2 ≥ 0.999). The extraction recovery was within 70.2–89.2% with relative standard deviations of less than 8.1%. This method was simple, fast, and environmentally friendly, and was successfully applied to extract and analyze pyrethroids in Agaricus bisporus, Lentinula edodes, Auricularia auricular, and Flammulina velutiper.

“…This method has proved to be efficiently to extract organic and inorganic compounds in environmental samples. 23,24 However, the experimental temperature was greatly restricted by the melting point of the available organic extractant. Therefore, we need to search some new extractant to enlarge the application range of the DLLME-SFOD.…”

“…Nevertheless, using a mixture of acetonitrile/tetrahydrofurane in this method instead of acetonitrile alone enhanced recoveries of most compounds from salmon. Another group of researchers opted for QuEChERS followed by the DLLME-SFO technique for cleanup of tilapia samples for determining organochlorine pesticides by GC-ECD, achieving recoveries > 88% [ 41 ].…”

The use of pesticides and veterinary drugs results in the appearance of residues of xenobiotics in foods. Thus, several methods have been developed for monitoring them; however, most are tedious and expensive. By contrast, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology involves a microextraction that yields small samples and has been applied for the analysis of various xenobiotics including pesticides, antibiotics, and mycotoxins. QuEChERS has shown advantages over other techniques including fast sample preparation, reduced needs for reagents and labware, and versatility. This approach allows the simultaneous determination of pesticides with various polarities and volatilities and can be easily modified for the analysis of a wide range of xenobiotics in various matrices including animal products rich in fat. Nevertheless, to attain high recoveries, the extraction, cleanup, and concentration steps have to be optimized according to the target compounds and matrix. Hence, QuEChERS is a promising and environmentally friendly methodology for the high-throughput routine analysis of xenobiotics in animal products. This review focuses on the application of QuEChERS to foods of animal origin and describes recent developments for the optimization of the analysis of veterinary drugs, pesticides, polycyclic aromatic hydrocarbons, and other compounds of concern.
