“…SPME is more commonly employed alongside GC-MS, whereas MEPS, a miniaturised version of SPE, is fully compatible with LC-MS, with the latter now more routinely employed for the analysis of mycotoxins, and in particular the type-A trichothecenes such as HT-2 and T-2. Furthermore, due to their size, SPME and MEPS are more suited to small volumes of biological fluids for the analysis of mycotoxins and their metabolites rather than in foodstuffs [ 134 ].…”

One of the major classes of mycotoxins posing serious hazards to humans and animals and potentially causing severe economic impact to the cereal industry are the trichothecenes, produced by many fungal genera. As such, indicative limits for the sum of T-2 and HT-2 were introduced in the European Union in 2013 and discussions are ongoing as to the establishment of maximum levels. This review provides a concise assessment of the existing understanding concerning the toxicological effects of T-2 and HT-2 in humans and animals, their biosynthetic pathways, occurrence, impact of climate change on their production and an evaluation of the analytical methods applied to their detection. This study highlights that the ecology of F. sporotrichioides and F. langsethiae as well as the influence of interacting environmental factors on their growth and activation of biosynthetic genes are still not fully understood. Predictive models of Fusarium growth and subsequent mycotoxin production would be beneficial in predicting the risk of contamination and thus aid early mitigation. With the likelihood of regulatory maximum limits being introduced, increased surveillance using rapid, on-site tests in addition to confirmatory methods will be required. allowing the industry to be proactive rather than reactive.

“…However, various mycotoxins may coexist at extremely low concentrations in food, and considering the complexity of food matrices, it is necessary to purify the food matrix during the detection process while achieving the enrichment of low-concentration mycotoxins to meet the requirements of instrument analysis [ 29 ]. In response to this challenge, novel purification materials with nanoscale features or exceptional structural characteristics have been continuously developed and used in combination with various large-scale analytical instruments, such as chromatography and mass spectrometry, achieving accurate and sensitive detection of mycotoxins in complex food matrices [ 30 , 31 , 32 ]. Table 2 illustrates the application of various nanoscale materials in solid-phase extraction (SPE) and solid-phase microextraction (SPME) processes for the detection of mycotoxins in food.…”

Trace amounts of mycotoxins in food matrices have caused a very serious problem of food safety and have attracted widespread attention. Developing accurate, sensitive, rapid mycotoxin detection and control strategies adapted to the complex matrices of food is crucial for in safeguarding public health. With the continuous development of nanotechnology and materials science, various nanoscale materials have been developed for the purification of complex food matrices or for providing response signals to achieve the accurate and rapid detection of various mycotoxins in food products. This article reviews and summarizes recent research (from 2018 to 2023) on new strategies and methods for the accurate or rapid detection of mold toxins in food samples using nanoscale materials. It places particular emphasis on outlining the characteristics of various nanoscale or nanostructural materials and their roles in the process of detecting mycotoxins. The aim of this paper is to promote the in-depth research and application of various nanoscale or structured materials and to provide guidance and reference for the development of strategies for the detection and control of mycotoxin contamination in complex matrices of food.

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.
