“…The photocatalytic mechanism was suggested: MeOH, H 2 O, or CH 3 COCH 3 formed potential free radicals (H • , OH • , OMe • , or CH 3 COCH 2 • ) under UV irradiation. Then, H • attacked on the double bond (C-8 or C-9) leading to form carbon-free radicals, which was then coupled with OH • , OMe • , or CH 3 COCH 2 • to shape degraded products 1–3 and 5–7 ( Waiss and Wiley, 1969 ; Iyer et al, 1994 ; Jamil et al, 2017 ; Mao et al, 2019 ). In addition, O 2 in the air under UV irradiation could form O 2 •- , which could attack on the double bond C-8/C-9 to produce 8,9-epoxide-AFB 1 .…”

Analysis, purification, and characterization of AFB1 degraded products are vital steps for elucidation of the photocatalytic mechanism. In this report, the UPLC-Q-TOF-MS/MS technique was first coupled with purification and NMR spectral approaches to analyze and characterize degraded products of AFB1 photocatalyzed under UV irradiation. A total of seventeen degraded products were characterized based on the UPLC-Q-TOF-MS/MS analysis, in which seven ones (1–7) including four (stereo) isomers (1,2, 5, and 6) were purified and elucidated by NMR experiments. According to the structural features of AFB1 and degraded products (1–7), the possible photocatalytic mechanisms were suggested. Furthermore, AFB1 and degraded products (1–7) were evaluated against different cell lines. The results indicated that the UPLC-Q-TOF-MS/MS technique combined with purification, NMR spectral experiments, and biological tests was an applicable integrated approach for analysis, characterization, and toxic evaluation of degraded products of AFB1, which could be used to evaluate other mycotoxin degradation processes.

Exposure to mycotoxins is a worldwide concern as their occurrence is unavoidable and varies among geographical regions. Mycotoxins can affect the performance and quality of livestock production and act as carriers putting human health at risk. Feed can be contaminated by various fungal species, and mycotoxins co-occurrence, and modified and emerging mycotoxins are at the centre of modern mycotoxin research. Preventing mould and mycotoxin contamination is almost impossible; it is necessary for producers to implement a comprehensive mycotoxin management program to moderate these risks along the animal feed supply chain in an HACCP perspective. The objective of this paper is to suggest an innovative integrated system for handling mycotoxins in the feed chain, with an emphasis on novel strategies for mycotoxin control. Specific and selected technologies, such as nanotechnologies, and management protocols are reported as promising and sustainable options for implementing mycotoxins control, prevention, and management. Further research should be concentrated on methods to determine multi-contaminated samples, and emerging and modified mycotoxins.

“…Thus, a simple, highly efficient, and safe degradation technology is urgently required for the mycotoxin detoxification. In recent years, photocatalytic degradation as a progressive oxidation technology have exhibited an enormous potential in the detoxification of mycotoxins due to their merits of low cost, environmental‐friendly, easy operation at only mild pressure and temperature conditions, and no secondary pollution (Bai et al., 2017; Jamil, Abbas, Nasr, El‐Kady, & Ibrahim, 2017). Amazingly, the state‐of‐the‐art nanomaterials have played a key role on the photocatalytic degradation of mycotoxins and have gradually been an attractive study hotspot in mycotoxin detoxification fields (Wu et al., 2020; Zhou et al., 2020).…”

Mycotoxins, a toxic secondary metabolite, unpredictably, and unavoidably occur in foods and feeds, leading to adverse health impacts and enormous economic losses in the agriculture industry. Moreover, mycotoxin contamination has been a great threat for the public health and agriculture economy development worldwide. Therefore, the control of the mycotoxin contamination is of great importance and has caused rising concern worldwide. Recently, emerging nanomaterials have been promisingly applied in the control of mycotoxin contamination and have obtained many achievements. In this review, first of all, the type, occurrence, and toxicity of mycotoxins are simply discussed. Then, attentions are focused on the applications of emerging nanomaterials to controlling the mycotoxin contamination, including mycotoxin assay, the inhibition of mycotoxin production, the adsorption of mycotoxins, and mycotoxin elimination. In the end, the future opportunities and challenges on the toxicity, occurrence, and control of mycotoxins are tentatively put forward.
