The use of nanotechnology in the food sector exemplifies one of the most dynamic interactions among science, law, and ethics, offering both transformative opportunities and complex regulatory challenges. Legal responses to nanotechnology have evolved slowly, unevenly across jurisdictions, and often inconsistently, resulting in a globally fragmented regulatory landscape. A bibliometric analysis of the topic reveals the historical emergence of this issue, its current state of development, and prospective future trajectories. While certain regions, such as the European Union, have moved forward with more comprehensive frameworks, the achievement of global standardization remains elusive. This is due to ongoing scientific uncertainty and divergent ethical considerations and regulatory cultures. International bodies such as the Codex Alimentarius and the World Health Organization have engaged in the discourse, but progress has been hampered by conflicting definitions and political constraints. As a result, cross-border trade and innovation face significant obstacles, underscoring the urgent need for coordinated legal strategies. Effective governance must incorporate not only risk assessment and formal regulatory procedures but also ethical standards, transparency, and public participation in decision-making. As legal frameworks increasingly incorporate ethical dimensions, they must evolve into participatory, science-based, and anticipatory models capable of managing the promises and risks inherent in nanotechnology in the food sector. Only through sustained international collaboration, robust scientific research, inclusive legal reform, and active social participation can consumer trust be preserved and the full potential of nanotechnology be realized responsibly.
