Nutraceutical benefits of brown macroalgae Durvillaea antarctica: a bibliometric review

Durvillaea antarctica, commonly known as Cochayuyo in Chile and Bull kelp in southern New Zealand, is a brown macroalgae recognized for its notable nutritional value. This includes high omega-3 essential fatty acids, vitamins, and particularly dietary ber. Furthermore, it is acknowledged as a nutraceutical due to its antioxidative, anti-in ammatory, anticancer, antiviral, and anti-diabetic properties. An emerging industrial application involves using it as a reinforcing material in active food packaging with antioxidant capabilities. A comprehensive analysis was conducted wherein the Scopus database was used to conduct the initial bibliometric investigation encompassing the years since 1979. The search yielded 198 documents published in English, comprising 182 articles, 6 conference papers, 4 reviews, 3 book chapters, 1 note, 1 letter, and 1 erratum. Chile and New Zealand notably demonstrated high productivity, contributing more than 70 documents each. The most contributing authors, institutions, and journals in the eld were systematically recorded. D. antarctica, due to its mounting scienti c signi cance, is readily accessible in the temperate waters of the Southern hemisphere, o ering substantial health and societal advantages. Bibliometrics was employed to generate graphical representations and thoroughly examine the most frequently cited documents, author networks, collaborative interactions, and topic categorization. The keywords were organized into clusters, one focused on phylogenetics and three centered on chemistry and metabolism, the physiology of brown algae phaeophyta, and the marine ecosystem, macroalgae, and biogeography. The analysis also highlighted the top three countries contributing to research in this domain: Chile, New Zealand, and Australia. This bibliometric and nutraceutical investigation serves as compelling evidence supporting the myriad applications of D. antarctica biocultural value in food science and technology, o ering valuable insights to inform policy decisions.
