Applications and Outlooks for MOFs in Food Engineering

Abstract

Food detection and food packaging play critical roles in the realm of food engineering in maintaining food safety and quality. Because of the specific large surface area (SSA) and customizable topologies, metal-organic frameworks (MOFs) have become recognized as promising materials with distinctive features. Examples of MOFs employed as photochemical and electrochemical sensors for food detection are provided in this research. These MOF-based sensors have great selectivity and sensitivity, making it possible to quickly and accurately identify pollutants or signs of food rotting in samples. Additionally, the use of MOFs in food packaging has advantages including a longer shelf life and antibacterial qualities. Food is protected from outside influences by being enclosed within MOF structures, which delays deterioration and rotting. Additionally, MOFs with antibacterial qualities can successfully stop the growth of microbes, ensuring the safety of food. MOFs have the potential to be used in new application areas, such as the controlled release of dietary supplements and flavor enhancers, in addition to food detection and packaging. To guarantee the stability and effectiveness of MOFs in various applications, additional study is necessary. The relevance of food detection and packaging in food engineering is highlighted in this paper's conclusion, which also explores the potential of MOFs as adaptable tools in both fields. The examples shown show how important MOFs are as sensors and packaging materials, but further study is needed to fully utilize their potential and address any issues that might arise.
