“…Therefore, further studies are necessary to better correlate food processing conditions with mycotoxin formation in cashew nuts. Work by Li et al [ 83 ] developed a method for the detection of mycotoxins in a complex matrix, such as vegetable oil. The comprehensive analysis of 20 commercial vegetable oils revealed that AFB1 and AFB2, followed by ZEN, were the most frequent mycotoxins observed.…”

Mycotoxins are well-known secondary metabolites produced by several fungi that grow and occur in different crops during both pre-harvest and post-harvest conditions. The contamination and occurrence of mycotoxins currently represent some of the major issues in the entire agri-food system. The quantification of mycotoxins in different feeds and foodstuffs is extremely difficult because of the low concentration ranges; therefore, both sample collection and preparation are essential to providing accurate detection and reliable quantification. Currently, several analytical methods are available for the detection of mycotoxins in both feed and food products, and liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) represents the most reliable instrumental approach. In particular, the fast development of high-throughput methods has made it possible to screen and analyze, in the same analytical run and with high accuracy, multiple mycotoxins, such as those regulated, masked, or modified, and emerging ones. Therefore, the aim of this review is to provide an overview of the state of the art of mycotoxins occurrence, health-related concerns, and analyses, discussing the need to perform multi-screening approaches combined with omics technologies to simultaneously analyze several mycotoxins in different feed and food matrices. This approach is expected to provide more comprehensive information about the profile and distribution of emerging mycotoxins, thus enhancing the understanding of their co-occurrence and impact on the entire production chain.

The efficient solid-phase extraction (SPE) adsorbents for the detection of trace mycotoxins are challenging to prepare in an essential sample pretreatment. In this study, an efficient SPE adsorbent, an electrospun polystyrene/polyacrylonitrile nanofiber membrane modified by polydopamine (PDA@PS/PAN NFM), was prepared and characterized. It is shown that the introduction of PDA provided abundant amino groups and phenolic hydroxyl groups for the porous network structure of these nanofibers, which can contribute rich interactions (such as hydrogen bonding, electrostatic interaction, and π−π stacking) on the analyte to improve the extraction efficiency of sample pretreatment. The extraction performance of PDA@PS/PAN NFM was probed by selecting zearalenone (ZEN) as the representative mycotoxin, and the effects of several factors on the adsorption and desorption in the SPE process were systematically investigated and optimized. Under the optimal conditions, the limit of detection (LOD) was 4.17 μg/kg, the intraday and interday relative standard deviations (RSDs) were 3.3− 5.2 and 3.7−5.1%, respectively, and the recovery was 87.3−99.5%. Additionally, PDA@PS/PAN NFM displayed excellent reproducibility with a good reusability of 20 times. The results indicated that the PDA-functionalized nanofiber membrane exhibited extensive application prospects in the efficient separation, preconcentration, and decrease of interference of trace mycotoxins in a complex sample matrix.
