초록
This study analyzed 2,185 valid patents related to the upcycling of agricultural by-products filed and registered in Korea between 1966 and 2023 to identify the major technological and industrial trends. The number of patent applications increased rapidly after 2000, with an annual average of approximately 102 cases during 2010∼2019 and 117 cases since 2020, indicating sustained technological advancement. The compound annual growth rate (CAGR) for 2019∼2023 was 3.9%, suggesting steady technological stabilization. Individual inventors (41.8%) and corporations (37.0%) accounted for the largest proportions of applicants, followed by universities (13.1%). This distribution suggests that technological development in agricultural by-product upcycling is driven primarily by industry and academia, reflecting the research and innovation structure in which academic research and industrial application are closely interconnected. In the International Patent Classification (IPC), Section A (Human Necessities) dominated with 71.5%, particularly subclasses A61 (Medical or Hygienic) and A23 (Foodstuffs), showing that technological development is concentrated in health-related and food utilization fields. The major raw materials were grains, fruits, and vegetables, with functional parts such as husks, peels, and aerial parts used most frequently. Extraction (41.0%) remained the primary process, but biological conversion processes, including fermentation and enzymatic hydrolysis, have expanded to over 20% in the past five years, highlighting a shift toward functional enhancement. The functional claims primarily involved skin health (35.6%), antioxidant (28.4%), and immune support (26.6%) effects, while the industrial applications were centered on cosmetics, pharmaceuticals, industrial materials, and food sectors. These results highlight that upcycling technologies for agricultural by-products in Korea are evolving from basic recycling to advanced functional material production, providing an essential foundation for sustainable food systems and circular bioeconomy strategies that integrate environmental and economic value.
