AI 기반 식품공정 혁신과 지속가능한 대체식품 개발:연구 및 특허 동향 분석

Purpose: This study comprehensively analyzed technological trends and patent landscapes in the field of alternative foods, highlighting policy and industrial implications and anticipated technological achievements. Methods: The analysis examined 759 domestic and international research articles and 566 patents published between 2005 and 2025. Since 2020, research on alternative foods has increased rapidly, with artificial intelligence (AI) technologies being increasingly adopted, particularly in the development of food materials and the optimization of processing. Results: Patent analysis revealed a growing trend among global companies toward hybrid patent strategies that integrate data, processes, and consumer feedback, rather than focusing on single products. Moreover, the United States, Europe, and China are promoting the development of AI-based food industry ecosystems as part of their national strategies. South Korea has proposed policy directions, such as “fostering the food tech industry” and “AI-based digitization of food processes”. These technological and policy developments are driving the alternative food industry beyond simple protein replacement into an innovative pillar of a sustainable food system. Conclusion: This study is significant in that it demonstrates the feasibility of enhancing scientific and technological competitiveness in the alternative food industry, establishing policy support, and advancing the global sustainable food system through AI convergence technologies.
