The rising amount of food industry waste has sparked interest in its valorization as a source of bioactive compounds. This study combines bibliometric analysis and a systematic review to map the scientific literature on the recovery of bioactive compounds from food byproducts, focusing on green extraction strategies and their alignment with the principles of the circular economy. A total of 176 documents, published between 2015 and 2025, were analyzed. The analysis shows significant growth after 2020 and highlights bioactive compounds, extraction, and the circular economy as the primary research themes. Italy, Spain, and Brazil emerged as the leading countries in scientific production. The systematic review covers green extraction techniques, including ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE), enzyme-assisted extraction (EAE), and natural deep eutectic solvent extraction (NADES). UAE- and NADES-based processes were the most frequently applied extraction techniques, mainly targeting phenolic compounds and flavonoids. Significant progress has been observed, particularly in the advancement of extraction technologies, in the recovery of key bioactive compounds, and in their industrial applications. These methods recover phenolics, flavonoids, anthocyanins, and other compounds with antioxidant, antimicrobial, and cardioprotective properties, which have potential applications in functional foods, nutraceuticals, pharmaceuticals, cosmetics, and biodegradable packaging. Nutraceuticals and functional foods represent the main application areas, followed by cosmetics and pharmaceuticals. Despite progress, challenges remain, including scalability, equipment costs, solvent recovery, and process standardization. The green extraction of bioactive compounds from food byproducts shows promise and can support the goals of the 2030 Agenda.

Disability and Rehabilitation has a history of 45 years. This article aims to comprehensively analyze the scientific production of this journal to celebrate and present its achievements over time. This study examines the performance of the journal's publications between 1978 and 2022, using indicators of bibliometric analysis and scientific mapping techniques. These techniques explore publication trends, emerging and discussed themes, institutions, countries, collaboration patterns, and citations. In the journal's 45 years, 7369 documents were published, with an average annual growth rate of 15.18%, reaching 176976 citations in 7019 documents. The United Kingdom was the most productive, and the University of Toronto was the most representative (587 articles). Recurring themes were rehabilitation, stroke, and disability. The most consolidated research themes were rehabilitation, stroke, activities of daily living, and physiotherapy. This study contributes to scientific development in the field of disability and rehabilitation. The findings provide data to advance the understanding of academic practices in these fields and also provide valuable insights for the strategic planning, potential innovations, and future actions of the editorial board of the journal Disability and Rehabilitation.

The agri-food sector is expanding, driven by growing global demand. At the same time, it faces the challenge of increasing its efficiency and adopting sustainable practices. This study aimed to map scientific production in this field, identifying trends, emerging themes, critical gaps, and future directions for research. A bibliometric analysis was conducted with 5141 papers published between 1977 and 2024, extracted from the Scopus and Web of Science databases. We applied keyword co-occurrence analysis, thematic analysis, thematic evolution, and three-field graphs using the metrics betweenness centrality, closeness centrality, and PageRank. The results revealed a significant growth in publications in the agri-food sector, especially after 2012, emphasizing the high centrality and relevance of themes such as sustainability, agri-food, and agriculture. Topics such as bioactive compounds, blockchain, and traceability were identified as areas of growing interest, and the circular economy stood out as an emerging topic. Italy, Spain, and France lead in scientific production and international collaboration. The most prominent journals were Sustainability, the Journal of Cleaner Production, and Agriculture and Human Values. Research in the sector is expanding, focusing on sustainability, the circular economy, and bioactive compounds. International collaborations and high-impact journals are pillars for advances in the sector.

This article identifies and analyzes initiatives to stimulate the creation of spin-offs in seven universities. For this, we developed a multiple case study at the University of Georgia, University of California, the Polytechnic University of Valencia, University of Porto, the University of Cambridge, the University of Strathclyde and the University of Bristol. Interviews, as well as observations and documentary analysis were conducted in these institutions. The results achieved were then compared. Among the identified initiatives, we observed the capital participation in all universities and also proof of concept funding in the universities of Georgia and California.
