Current Status and Emerging Trends in Research on Postharvest Preservation of Edible Fungi: A Bibliometric Analysis Based on Web of Science

Postharvest preservation of edible fungi is crucial for promoting the healthy development of the edible fungi industry. To systematically review the development history of research on postharvest preservation of edible fungi and to predict future trends, this paper used bibliometric methods to analyzes 421 pieces of relevant literature published in the Web of Science database between 2000 and the first three quarter of 2022 in terms of literature publishing, research collaboration, key authors, important literature, literature citations, and keywords. CiteSpace software was used for visual analysis. The results indicated that the amount and citations of literature on the preservation of edible fungi had steadily increased since 2000, with a trend of rapid growth since 2015 until the third quarter of 2022. Chinese research institutions and authors had significant impact in this field, who had participated in international collaboration most extensively and produced the most research achievements. The analysis of literature citations and keywords revealed that the frontier hotspots in this field were cell wall metabolism, energy metabolism, and active packaging research. The direction of energy metabolism was particularly noteworthy. Maintaining normal cell energy metabolism and antioxidant activity is essential for edible fungi to resist postharvest deterioration. Therefore, exploring new preservation technologies and elucidating their molecular mechanisms will be an important research direction in the future.
