Food safety has become a major challenge in global public health. To address the limitations of traditional plastic packaging and laboratory-based detection methods, innovative solutions are needed to solve contamination risks and preservation of food. This review synthesizes recent advances in combining natural polysaccharides (cellulose, chitosan, alginate, etc.) with functional nanomaterials (silver nanoparticles, carbon dots, metal-organic frameworks, etc.) in food safety, focusing on the role of polysaccharides and nanomaterials in packaging and contaminant detection and the application o...
