“…MeCN was the solvent that presented the best peak efficiency for all compounds. Under optimum conditions, this NACE method allowed the separation of ENNs and BEA in less than 4 min, which is faster than recent methods based on LC [8,[24][25][26].…”

“…Dispersive solid phase extraction is one of the commonly used extraction processes for the application of magnetic nanomaterials. This technique has been applied in determining pesticides and other pollutants, including mycotoxins in food and environmental samples [ 110 , 130 , 131 ].…”

“…It is a key way in identifying emerging pollutants or contaminants by screening the matrices without reference standards, and there are no limitations to the number of analytes that can be detected. This analysis uses high-resolution mass spectrometry (HRMS), specifically quadrupole, with time-of-flight hybridization and Orbitrap™ instruments [ 130 ]. The key features of this analysis is that a fingerprint known as a total ion chromatograph is obtained for each sample, which is used to compare with existing sample profiles to reveal deviations or helps in the identification of unknowns [ 193 ].…”

“…For example, Jin et al [ 195 ] did non-target analysis in vegetables using hierarchial micro and mesosphere metal-organic framework coated with magnetic nanosphere (H-MOF@Fe 3 O 4 ). Non-target analysis was conducted using magnetic nanocomposite based on cellulose (Fe 3 O 4 @Cellulose) and different metabolites of enniatins and beauvericins screened in paprika samples [ 130 ]. In another study, a non-target analysis of over 204 pesticides was carried out by developing a magnetic blade-spray tandem mass spectrometry assay (MBS-MS/MS) [ 196 ].…”

Environmental pollutants, such as mycotoxins, pesticides, and pharmaceuticals, are a group of contaminates that occur naturally, while others are produced from anthropogenic sources. With increased research on the adverse ecological and human health effects of these pollutants, there is an increasing need to regularly monitor their levels in food and the environment in order to ensure food safety and public health. The application of magnetic nanomaterials in the analyses of these pollutants could be promising and offers numerous advantages relative to conventional techniques. Due to their ability for the selective adsorption, and ease of separation as a result of magnetic susceptibility, surface modification, stability, cost-effectiveness, availability, and biodegradability, these unique magnetic nanomaterials exhibit great achievement in the improvement of the extraction of different analytes in food. On the other hand, conventional methods involve longer extraction procedures and utilize large quantities of environmentally unfriendly organic solvents. This review centers its attention on current applications of magnetic nanomaterials and their modifications in the extraction of pollutants in food commodities.

“…Paprika mycotoxin contamination has been studied, with OTA and AFB1 showing the highest occurrence [ 24 , 25 ]. Recently, the presence of emerging mycotoxins has also been reported in paprika samples, particularly in enniatin B1 [ 26 ]. Current legislation of the European Union [ 27 ] sets maximum regulated levels of 5 µg kg −1 AFB1 and 10 µg kg −1 for the sum of AFB1, B2, G1 and G2 and otherwise the Food and Agriculture Organization (FAO) set the same regulation.…”

Dispersive magnetic solid-phase extraction (DMSPE) technique is proposed as a new sensitive and effective sample treatment method for the determination of aflatoxins in paprika samples. DMSPE was followed by ultrahigh-performance liquid chromatography and high-resolution mass spectrometry detection (UHPLC-HRMS) using a non-targeted acquisition mode for the detection of main aflatoxins (aflatoxin G1, G2, B1 and B2) and derivatives. DMSPE was based on the use of magnetic nanocomposite coated with polypyrrole (PPy) polymer and the main experimental parameters influencing the extraction efficiency in adsorption and desorption steps have been studied and optimized. Analyses were performed using 250 µL magnetic PPy nanocomposite into the sample solution, adsorbing the analytes in 30 min and desorbing them with ethyl acetate (2 mL) in 15 min. The method has been validated, obtaining quantification limits between 3.5 and 4.7 µg kg−1 and recoveries between 89.5–97.7%. The high recovery rate, wide detection range and the use for the first time of the reusable Fe3O4@PPy nanomaterial in suspension for solid food matrices, guarantee the usefulness of the method developed for adequate control of aflatoxins levels in paprika. The proposed methodology was applied for the analysis of 31 samples (conventional and organic) revealing the absence of aflatoxins in the samples.
