Bibliometric analysis on pseudocereals

Abstract

A bibliometric analysis on scientific documents regarding pseudocereals was performed. The literature was extracted from Web of Science database with limitations on language and index, resulting in 438 documents published until 2022. The bibliographic data were analyzed using Bibliometrix package and Biblioshiny interface available on R statistical language. The first source on pseudocereals was published in 1982 according to our data collection, and there was an increased trend of publications over the time with annual production above 11 %. The core group consisted of 11 out of 175 journals publishing on the field. Italy made the largest contribution, followed by Spain, Mexico, USA, China, among others. Collaboration network analysis was run to map associations between top countries on pseudocereals research. Six distinct sub-clusters of countries tending to collaborate together were detected. All of the publications of Israel on the area were in collaboration with other countries, whereas Argentina and Turkey published only single country publications. The most commonly used author keywords displayed with the word cloud after pseudocereals were quinoa, amaranth, buckwheat, and gluten-free. Other notable keywords were food composition, antioxidant activity, fermentation, bread, celiac disease, lactic acid bacteria, etc. The objective of the current study is to illustrate emerging trends in journal performance, collaboration networks, research constituents, intellectual structure, and evolutionary nuances of the field, thus also supporting policy development to promote research on pseudocereals utilizing bibliometrics approach.
