Abstract

This study aims to systematically explore the knowledge map and development trends of blueberry quality research in China using bibliometric and knowledge mapping approaches. By analyzing 500 relevant articles from the China National Knowledge Infrastructure (CNKI) database (2004–2025), a multi-dimensional visualization was conducted using CiteSpace software. The findings show that the volume of publications on blueberry quality research in China has increased steadily and reached a phase of stabilization. Four core research clusters were identified: quality analysis and evaluation, postharvest storage and preservation technology, processing technology and product development, and variety resources and cultivation physiology. The research hotspots have evolved over time, starting with basic quality characterization and progressing to the exploration of functional components such as anthocyanins, optimization of postharvest technologies, and more recently, a focus on deep processing, flavor quality, molecular mechanisms, and intelligent control techniques. Prominent institutions, such as Jilin Agricultural University, play a leading role, though greater cross-institutional collaboration is needed. A relatively mature knowledge framework for blueberry quality research has been established in China. Moving forward, efforts should focus on enhancing interdisciplinary integration, investigating the mechanisms behind functional components, precisely regulating quality formation, and accelerating the translation of research outcomes into industrial applications. These efforts will provide a scientific foundation and strategic direction for the sustainable and healthy development of China’s blueberry industry.
