Food samples such as milk, beverages, meat and chicken products, fish, etc. are complex and demanding matrices. Various novel materials such as molecular imprinted polymers (MIPs), carbon-based nanomaterials carbon nanotubes, graphene oxide and metal-organic frameworks (MOFs) have been recently introduced in sample preparation to improve clean up as well as to achieve better recoveries, all complying with green analytical chemistry demands. Metal-organic frameworks are hybrid organic inorganic materials, which have been used for gas storage, separation, catalysis and drug delivery. The last few years MOFs have been used for sample preparation of pharmaceutical, environmental samples and food matrices. Due to their high surface area MOFs can be used as adsorbents for the development of sample preparation techniques of food matrices prior to their analysis with chromatographic and spectrometric techniques with great performance characteristics.
食品样品，如牛奶、饮料、肉类和鸡肉产品、鱼类等，是复杂且要求较高的基质。最近，各种新型材料，如分子印迹聚合物（MIPs）、碳基纳米材料（碳纳米管、氧化石墨烯和金属有机骨架（MOFs））已被引入样品制备中，以提高净化效果并实现更好的回收率，所有这些都符合绿色分析化学的要求。金属有机骨架是一种混合有机-无机材料，已被用于气体储存、分离、催化和药物输送。在过去的几年中，MOFs 已被用于药物、环境样品和食品基质的样品制备。由于其高表面积，MOFs 可用作食品基质样品制备技术的吸附剂，然后用色谱和光谱技术进行分析，具有出色的性能特点。
