“…They combine the properties of nanomaterials and oxidases in a more stable and efficient system. Nanozymes with laccase and peroxidase-like activities were developed for contaminant removal, including AFB 1 ( Zhang et al, 2020 ; Guo et al, 2021 ; Wei et al, 2022 ). Nanozyme show also adsorptive characteristics due to the hierarchical porous structure ( Wu et al, 2020 ; Ma et al, 2021 ; Pérez-Gómez et al, 2022 ) and can combine filtration, adsorption, and catalysis in a multifunctional removal process ( Ren et al, 2019 ).…”

“…These studies show that these innovative materials possess high efficiency (up to 96%), stability, and reusability (up to 5 cycles). Few authors investigated the effectiveness on real matrices ( Ma et al, 2021 ; Wei et al, 2022 ) and the toxicity of both nanozyme and degradation products ( Wei et al, 2022 ). These data are promising, as high removal rates were obtained in vegetable oils, with little impact on their quality.…”

Aflatoxins are toxic secondary metabolites produced by Aspergillus spp. found in staple food and feed commodities worldwide. Aflatoxins are carcinogenic, teratogenic, and mutagenic, and pose a serious threat to the health of both humans and animals. The global economy and trade are significantly affected as well. Various models and datasets related to aflatoxins in maize have been developed and used but have not yet been linked. The prevention of crop loss due to aflatoxin contamination is complex and challenging. Hence, the set-up of advanced decontamination is crucial to cope with the challenge of climate change, growing population, unstable political scenarios, and food security problems also in European countries. After harvest, decontamination methods can be applied during transport, storage, or processing, but their application for aflatoxin reduction is still limited. Therefore, this review aims to investigate the effects of environmental factors on aflatoxin production because of climate change and to critically discuss the present-day and novel decontamination techniques to unravel gaps and limitations to propose them as a tool to tackle an increased aflatoxin risk in Europe.

“…Most conventional MOFs are difficult to be biologically active as a chemical material. Recently, Wei et al (2022) used the graded porous properties of MOFs to synthesize PCN-222 with peroxidase-like activity, which derives its biological activity from Fe-TCPP (TCPP = tetrakis (4-carboxyphenyl) porphyrin), and the peroxidase-like activity can be further enhanced by loading Pd nanoparticles onto PCN-222. The composite material was used for the adsorption and removal of AFB1 from edible oil, with an adsorption and removal rate of 96.52% by testing.…”

Metal-organic framework materials (MOFs) have been widely used in food contamination adsorption and detection due to their large specific surface area, specific pore structure and flexible post-modification. MOFs with specific pore size can be targeted for selective adsorption of some contaminants and can be used as pretreatment and pre-concentration steps to purify samples and enrich target analytes for food contamination detection to improve the detection efficiency. In addition, MOFs, as a new functional material, play an important role in developing new rapid detection methods that are simple, portable, inexpensive and with high sensitivity and accuracy. The aim of this paper is to summarize the latest and insightful research results on MOFs for the adsorption and detection of food contaminants. By summarizing Zn-based, Cu-based and Zr-based MOFs with low cost, easily available raw materials and convenient synthesis conditions, we describe their principles and discuss their applications in chemical and biological contaminant adsorption and sensing detection in terms of stability, adsorption capacity and sensitivity. Finally, we present the limitations and challenges of MOFs in food detection, hoping to provide some ideas for future development.
