Research Status and Trend Analysis of Digitally Enabled Agricultural Product Packaging: A Visual Analysis Based on Knowledge Graph

Digital integration in agricultural systems is intensifying the demand for intelligent packaging solutions that enhance food safety, reduce losses of perishable goods, and promote environmental sustainability. This study conducts a bibliometric analysis using Knowledge Graph on relevant publications retrieved from the Web of Science to map the evolutionary trajectory of digitally enabled agricultural packaging research. The results indicate sustained and robust growth in publication output, fueled by interdisciplinary convergence among food science, materials engineering, and computer science. The core research themes have evolved from an early focus on passive preservation techniques toward active and intelligent monitoring systems, with dominant topics including smart sensors, sustainable materials, and data-driven supply chain optimization. Emerging research frontiers increasingly emphasize sustainable packaging solutions that incorporate advanced tracking technologies and circular economy principles to minimize ecological impact. Future advancements will likely rely on cross-disciplinary artificial intelligence solutions, the establishment of standardized sustainability metrics, and deeper integration with digital supply chain infrastructures to overcome scalability challenges within global digital agricultural networks.
