Bioactive collagen peptides: bibliometric approach and market trends for aquatic sources

Abstract

The development of the collagen peptides industry is associated with new consumption trends among the population, projected to reach a value of 795 million USD by 2025. Given the relevance of the topic, the present work provides an overview of collagen, its sources, applications, as well as the properties and bioactivities of the peptides formed from its hydrolysis. In addition, a bibliometric analysis was performed to highlight a global overview of publication trends, co-authorship, and co-occurrence of keywords. Bibliometric data were obtained from the Web of Science platform using the descriptors “marine collagen peptide,” “marine collagen peptides,” “aquatic collagen peptide,” “aquatic collagen peptides,” “marine collagen hydrolysate,” “marine collagen hydrolysates,” “aquatic collagen hydrolysate” and “aquatic collagen hydrolysates” and the Boolean operator “OR,” to include terms that cover the possible variations used in the search. From the results obtained, articles and reviews published between 2000 and 2021 were selected. From the analysis of the data collected, it became evident the still relatively recent nature of the research on collagen peptides derived from aquatic organisms and the role of countries in Asia and Europe as leaders in the segment. The co-authorship analysis reveals that the collaboration network between authors/institutions is still scarce and strongly restricted to researchers/institutions in the same region. The co-occurrence analysis reveals that most of the works are related to the health area, highlighting its potential in the prevention/treatment of diseases. In view of the results obtained, it is expected that the growth of the production and commercial branch of these peptides will be accompanied by the amplification of collaboration between authors and institutions from different territories, establishing a global network of partnerships.
