However, mycotoxin contamination poses a significant threat by compromising grain quality and consumer health. Various decontamination techniques are employed to inactivate toxins, each with distinct mechanisms of toxin inactivation. This review examines the pivotal mechanisms in reducing mycotoxin levels in stored grains, elucidating the principles and pathways underlying novel decontamination techniques such as cold plasma, ozone, photocatalysis, nanoparticle adsorbents, and microbial enzymes, and assesses their practical application and industrial feasibility. Our thorough investigation reveals that the effectiveness of decontamination techniques relies on three fundamental mechanisms: adsorption, treatment with reactive chemical species, and biotransformation. Several novel technologies are highly effective in laboratory tests, but face challenges at the industrial scale. Current research indicates that novel decontamination techniques, including pulsed light, photocatalysis, and microbial enzymes, hold much promise in significantly reducing fungal growth and mycotoxin contamination in grains. However, it is also evident that techniques with high efficacy in reducing fungal infestations are not necessarily effective in eradicating mycotoxin contamination. A combinatory approach to these techniques is the way forward, and future research should focus on hybrid treatments to enhance the effectiveness of these technologies on an industrial scale. This review aims to bolster food safety and mitigate economic losses linked to mycotoxin contamination in grains by offering a theoretical basis for developing and implementing effective decontamination strategies.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102486"},"PeriodicalIF":2.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study first evaluated the impact of <em>T. castaneum</em> infestation on the nutritional parameters of stored wheat flour. Infested flour exhibited reductions in total soluble sugars, triacylglycerol levels, and unsaturated fatty acids, particularly Oleic and Linoleic acid, while secondary metabolites such as phenolics, flavonoids, and tannins were increased. Behavioural assays revealed that adult beetles were significantly more attracted towards infested flour odour due to the presence of 4,8-Dimethyldecanal (4,8-DMD), an aggregation pheromone of <em>T. castaneum</em>. Another key compound in infested flour, 1-Pentadecene, derived from the beetles' cuticular wax, was found to influence adult beetle behaviour. At higher concentrations, 1-Pentadecene acted as a repellent for the species. Molecular docking studies suggested that 1-Pentadecene competes with 4,8-DMD for binding to the odorant receptor TcOR1, which could potentially inhibit aggregation behaviour and reduce population growth. The docking analysis revealed that 1-Pentadecene interacts with the same binding pocket on TcOR1, sharing key amino acids (MET49, PHE69, THR72, GLN73, THR134, VAL135, TYR138, LEU154, ILE177, GLY180, ALA181, TYR286) and forming similar intermolecular bonds, such as a pi-alkyl bond, with a binding affinity (ΔG = −5.7) comparable to 4,8-DMD (ΔG = −5.8).
