The work aims to systematically introduce the preparation and application of micronano porous polymers in food packaging and detection. The base material and preparation methods of micronano porous polymers applied in current food industry were analyzed based on literature study; meanwhile, the application of micronano porous polymers in food industry was discussed. Micronano porous polymer could be combined with active packaging technology and food detection technology. It could be used directly as packaging materials, as well as load detection reagents or biological sensors, etc., and had many unique applications in the food industry. It was the key point for future research to develop more functions and applications of porous polymer and improve the preparation technology to make the manufacturing and application processes ecological. The micronano porous polymer, owing to its unique structure and function, will have a wide range of application prospects in future food industry.
