The demand for sustainability, product safety improvement and high quality standards have always been important in all areas of the biological sciences such as the food industry, which requires close monitoring and continuously throughout the food supply chain. In this area, the suitable and satisfactory food packaging in the industry is the basis for maintaining and preserving proper and suitable quality and safety in food. Despite the industry's efforts to produce safe products, food products may become contaminated during the process or from contaminated raw materials. Therefore, to solve the problems and defects related to food safety, several strategies and approaches have been considered and designed. Among various pathways the use of metal-organic frameworks is a new opportunity and challenges to ensure the quality and safety of food. Metal-organic frameworks are known as fundamental class of porous nonmaterial which has unique physical and chemical properties promising in a food safety program. These nanoporus materials have recently attracted a lot of attentions and have found their way into various industries, including the food industry, and have shown great potential for practical development because of a wide range of applications in diverse fields. This article tries to emphasize and introduce this technology with a brief overview of the use of metal-organic frameworks in the food industry in three subsets of packaging, storage and cleaning, and their applications in this industry and the advantages and benefits which come with using it. Results: In summary, it can be said that MOFs have shown exciting potential in the field of food safety and have shown all their efficiency through the ability to be used in different parts of the process. Emerging MOFs or composite-based MOFs have been considered as a practical coating in intelligent food packaging, for the controlled release of preservatives and to monitor food safety. Therefore, these materials need to have excellent adsorption and stability properties; Be further developed for use in packaging. MOFs have also been shown to be effective in eliminating hazardous substances in the food supply chain. Therefore, the need to synthesize new multifunctional MOFs to remove contaminants is essential. Finally, while MOFs are a promising substance to help improve food safety at various stages of the food chain; However, precise control of the pore size and volume of these frameworks for specific applications is still a challenge, so more attention needs to be paid to achieving high quality MOFs for use in food safety. Further research is also needed on the toxicity of MOFs. Manuscript profile -

These structures are a new class of porous materials, which are formed by connecting metal ions or clusters with polydentate organic ligands by covalent bonds. Compared to other porous compounds such as zeolites, silica, and activated carbon, coordination polymers are considered multifunctional materials with different properties due to the ability to adjust the surface of the cavity, size, shape, and functional groups of the surface of their cavities. For this reason, these compounds are used in different fields, including gas storage and absorption, manufacturing of various sensors, material separation, medical, biological, environmental and catalysis applications.

Using a co-precipitation method, the Fe3O4@SiO2 core was coated with Cu(OH)2 shell, which was then converted to CuBTC in a hydroethanolic mixture. Finally, a post-synthetic approach was used to manufacture a 3-(mercaptopropyl) trimethoxysilane functionalized Fe3O4@SiO2@Cu BTC nanocomposite. The resulting material is characterized using SEM-EDX, TEM, VSM, XRD, TGA, BET, UV–Vis, and FTIR techniques. TEM and SEM micrographs confirmed the core-shell structure. The resulting nanocomposite has high thermal stability, according to TGA findings. Because of their great biocompatibility and drug loading capability, coated Fe3O4@SiO2@Cu BTC nanoparticles might be perfect for drug delivery. Capecitabine (CAP), an anticancer medication, was successfully dispersed through MOF pores. The acquired data revealed that 91 percent of the CAP was adsorbed on the constructed framework, and that the release of capecitabine in PBS buffer solution (pH 5.7) at 37 °C took up to 60 hours to complete. The findings show that nano-sized MOFs-based magnetic NPs with high drug loading and acceptable biocompatibility are viable options for targeted drug delivery. Manuscript profile -

Sensors based on metal-organic frameworks have surpassed other chemical sensors in terms of construction cost, simplicity of the method, short response time, and good reversibility, and have been able to obtain a special place in the detection of toxic and hazardous pollutants. These nanoporous compounds, which are formed by the connection of metal centers and organic ligands through coordination bonding, have gathered the attention of many researchers due to their high chemical and thermal stability. The utilization of different aspects of the new synthetic and structural of this systems has led to a diverse success in the field of chemical and physical properties, many of which are unprecedented. Metal-organic frameworks have shown promising horizon in sensing applications due to having unique properties such as large sizes of cavities, high surface area, selected adsorption of small molecules and optical responses in the presence of guest molecules. In this article, we investigated the principles of the design of organic metal-framework sensors and the sensing mechanisms of these compounds. Manuscript profile
