A bibliometric analysis of the growing market of Spirulina-based algal products and emerging trends


Spirulina platensis is a photosynthetic filamentous cyanobacterium that is considered a ‘‘superfood’’ due to its high protein content and other valuable metabolites. There is a huge research gap in the field of Spirulina in Pakistan. This is the first paper focused on the analysis of the worldwide research and market trends of Spirulina-based bioproducts. The research trend analysis was carried out by using the Elsevier Scopus database to analyze the worldwide research trends in Spirulina-based bioproducts from 2000 to 2021. The number of publications, publications type, countries/territories, journals, and Spirulina research areas worldwide were focused to determine the evolution and latest tendencies in this field. The data showed that there is an emerging trend in different fields with a continuous increase in scientific articles. During the last twenty years, the highest number of publications came out of India followed by China and the United States. The most relevant journals publishing Spirulina research are Bioresource Technology, Journal of Applied Phycology, Aquaculture, and Algal research. Bibliometric analyses showed that the field of Agricultural and Biological Sciences has been the leading area followed by Biochemistry, Genetics, and Molecular Biology in terms of the highest number of articles published. Further, the industrial and market trend analyses showed that the Spirulina-based dietary supplement market is one of the most leading markets, it is predicted that by 2031 the market value would be USD 254 billion with 9.4% Compound Annual Growth Rate (CAGR). Therefore, in future the expectations are high for the production and commercialization of Spirulina-based bioproducts in Pakistan.
