近年来，金属有机框架在食品领域中的应用受到人们的关注。利用金属有机框架的吸附特性作为食品中有害物质检测的前处理手段是当前研究的一个热点。该文介绍了金属有机框架的合成方法、分类和吸附特性(以空隙率、密度、比表面积和孔径为指标)，并总结归纳了其在食品有害物质前处理过程中的应用，有害物主要包括重金属(Hg2+、Cu2+、Ni2+、Cr3+、Pb2+、Cd2+)、农药(烟碱类、三嗪类、苯脲类、有机磷类)、多环芳烃(萘、苊烯、苊等)和其他类物质(内分泌干扰物、抗生素、毒素等)。在此基础上提出了金属有机框架的发展前景。

In recent years, the application of metal-organic frameworks in the field of food has attracted increasing interests, such as using metal-organic frameworks in pretreatment procedure of harmful substances detection. This paper summarized recent research progress in understanding metal-organic frameworks′ synthesis, classification and adsorption characteristics (porosity, density, specific surface area, pore size). Also, the application of metal-organic frameworks in pretreatment procedure of harmful substances in foods was summarized, including the detection of heavy metals (Hg2+, Cu2+, Ni2+, Cr2+, Pb2+, Cd2+), pesticides (nicotine, triazine, phenylurea, organic phosphorus), polycyclic aromatic hydrocarbons (naphthalene, acenaphthylene, acenaphthene, etc.) and other substances (endocrine, disruptors, antibiotics, toxins, etc.). Future research in this area was also suggested.
