A 53-Year Bibliometric and Scientometric Analysis of Research in Culinary and Medicinal Mushrooms

The research field of culinary and medicinal mushrooms has been well developed since the first relevant publication in 1966. However, to date, there has been no bibliometric analysis published specifically for this field. This study aimed to assess the most influential publications as well as the research trends and important drivers in the field of culinary and medicinal mushrooms. Scopus was used to identify relevant publications and the 1000 most-cited publications were identified and analyzed. Bradford's law of scattering shows one-third of the papers were published in 14 core journals, with a total of 102 papers published in International Journal of Medicinal Mushrooms. There is an insignificant negative correlation (Pearson's correlation coefficient, r = -0.355) between the journal impact factor and publication count. VOSviewer was used to generate a country network. China represents Asia's research center in this field, having contributed 20% of the 1000 most-cited publications. A term map was also created to visualize the co-occurrence of key terms in the domain. Different biological activities such as antioxidant and antitumor properties of mushrooms appeared to be a recurring topic in this field. Wasser (2003) showed the highest citation count (n = 1282), which is almost double the second most-cited publication (n = 611). There is a weak positive correlation (r = +0.237) between the years since publication and total citation count. In conclusion, this bibliometric study will assist researchers to comprehend the current status of the research on culinary and medicinal mushrooms, and to visualize the future impact of such an important field.
