Mapping the global landscape of algae-based food research: A bibliometric analysis of trends, collaborations, and future directions.
Article in MethodsX, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study provides a comprehensive mapping of the global research landscape on algae, microalgae, and seaweed in food-related applications over the period 1989-2024, with particular emphasis on food additives, nutraceuticals, functional foods, and bioactive compounds. Based on 929 records retrieved from the Web of Science Core Collection, a tailored bibliometric framework is employed that integrates performance analysis, science mapping, thematic evolution, and reference-year analysis, thereby linking publication dynamics with the intellectual and conceptual structure of the field. The findings indicate a pronounced and sustained growth in algae-based food research, characterized by extensive international collaboration and a rising emphasis on functional ingredients and health-promoting compounds. Thematic and conceptual analyses delineate algal extracts, bioactive compounds, polysaccharides, proteins, and lipids as the principal knowledge clusters. The evolutionary trajectory of the field reveals a progression from primarily biochemical characterization toward more application-oriented research in food, nutraceutical, and functional health domains. Collectively, these results provide a systematic evidence base to support researchers, industry stakeholders, and policymakers in understanding current research priorities and in identifying emerging directions in algae-based food innovation.
