Research Progress, Challenges, and Future Trends of Modified Atmosphere Packaging (MAP) Technology for Food and...

Modified atmosphere packaging (MAP) is a preservation and packaging technology used to extend the shelf life of foods and agricultural products, maintain quality stability, and ensure food safety. To systematically review and summarize the current research landscape, technical challenges, and development trends in the MAP field, this study selected 1568 publications related to MAP from the Web of Science Core Collection (WOSCC) database during 2016-2025 and conducted bibliometric and visualization analysis. The results indicate that research activity in the MAP field has remained robust over the past decade, mainly focusing on four research areas: atmosphere regulation and packaging system design; microbial ecology, safety, and spoilage control; physicochemical deterioration and quality regulation; functional packaging materials and integrated preservation technologies. Countries such as China, Italy, and Spain have demonstrated outstanding performance in terms of publication output and academic influence in the MAP field, forming a solid research foundation in the MAP of perishable foods such as fruit and vegetables, meat products, and aquatic products. Research in the MAP field has gradually shifted from the verification of application effects toward system design and mechanistic analysis. Active packaging, intelligent packaging, bio-based materials, natural functional ingredients, volatile organic compounds, microbial community succession, and quality deterioration mechanisms have gradually become research hotspots, indicating a trend toward precision, sustainability, and functionality. These findings may provide references for future research topic selection, innovative packaging system design, and the development of novel food preservation technologies in the MAP field for foods and agricultural products.
