| 中文摘要:被真菌毒素污染的食品可引发严重的健康问题，如癌症和畸形等，已成为全球公共卫生关注的焦点。因此，精准检测食品中痕量真菌毒素对保障人类健康具有重要意义。真菌毒素在食品中的浓度水平较低且易与复杂的食品基质成分结合，基质干扰严重影响检测的灵敏度，需采用有效的样品前处理技术进行富集和净化。固相萃取作为一种高效的样品前处理技术，其关键取决于萃取材料。该文总结了过去5年固相萃取材料在食品中真菌毒素样品前处理方面的研究进展，并对未来发展方向进行了展望，以期为食品中真菌毒素快速高效分析方法的开发提供参考。 |

| Abstract:Mycotoxins infected foodstuffs may trigger serious health hazards,eg.cancers,deformity and mutation,which has been a global public health concern.Hence,accurate detection data is extremely important to determine the risk posed by mycotoxins to humans.Common detection methods could be used to detect mycotoxins effectively,but it is difficult to conduct any direct analysis if the contents of mycotoxins in complex matrices are rather low,and easy to combine with food matrix components.Consequently,effective sample pretreatment techniques are particularly important to analysis of mycotoxins in actual samples.Solid phase extraction(SPE) is an efficient technique for sample pretreatment,which mainly depends on the extraction materials.In recent years,continual appearances of new SPE materials such as multi walled carbon nanotubes,antibody,molecularly imprinted polymers and metal organic framework materials have contributed to the development and innovation of solid phase extraction technology.These advanced materials either have outstanding selectivity and excellent adsorption capacity toward a single target or could selectively adsorb multiple targets in complex matrix.In addition,the applications of new adsorption materials have greatly improved the recovery rate and detection sensitivity for target substances,shortened the sample pretreatment time,and made the pretreatment process more simple and environmental friendly.Progresses of advanced adsorption materials for mycotoxins sample pretreatment in the past five years are reviewed and summarized in this paper.Furthermore,the advantages,limitations and future trends of these advanced adsorbents are also discussed.Overall,sample pretreatment is promoted theoretically and practically with the development and application of advanced SPE materials.It is hoped that this review may provide a reference for the development of rapid and effective methods for analysis of fungal toxins in food. |
