Food technology, commonly referred to as “Food Tech,” is an emerging field that drives innovationby integrating Fourth Industrial Revolution technologies—such as artificial intelligence, robotics, and big data—across the entire food industry. Despite rapid growth in both domestic and global markets, existing research on food tech has been limitedby its reliance on survey-based studies and its narrow focus on specific sub-topics such as delivery applications and serving robots. To address these limitations, this study applies a combined approachincorporating keyword network analysis and LDA-based topic modeling to systematically and objectively examine the knowledge structure of food tech research in Korea.
A total of 118 food tech-related articles indexed in the Korea Citation Index (KCI) from January 2006 to July 2025 were analyzed. The analysis was conducted using TEXTOM, a text-mining platform that supports keyword frequency analysis (DF and TF-IDF), topic modeling, and network centrality analysis.
The results reveal several notable patterns. First, domestic food tech research expanded sharply after 2020, with 86.4% of all publications produced after this year—a trend strongly associated with the rise of contactless services during the COVID-19 pandemic. Second, disciplinary distribution shows a clear multidisciplinary orientation: social sciences accounted for the largest share (40.7%), followed by agricultural and marine sciences (19.5%), and engineering and interdisciplinary studies (11.9% each). Third, keyword analysis identified “customer satisfaction,” “service quality,” “serving robot,” “value,” and “visit intention” as key terms, indicating a research emphasis on service quality and consumer-oriented outcomes rather than technological development. Fourth, topic modeling produced seven major research themes, with “food service automation” representing the highest proportion (18.6%), followed by “market competitiveness and customer satisfaction” (17.8%) and “digital platforms and delivery services” (16.1%). In contrast, “alternative proteins and future foods” represented only 9.3%, suggesting that this area remains underdeveloped in domestic scholarship.
This study makes a methodological contributionby reducing researcher subjectivity through bibliometric techniques and by integrating micro-level keyword analysis with macro-level topic modeling. Furthermore, mapping the analytical results onto Digital Food Lab’s six-category classification shows that domestic research is heavily concentrated in the Food Service and Delivery & Retail domains, while foundational technology sectors—such as AgTech and Food Science—remain relatively underexplored. These findings are expected to help establish a globally competitive research agenda for Korean food tech studies. By identifying research gaps in foundational technology areas such as AgTech and Food Science, this study provides strategic directions for future research investment and policy development. The methodological framework combining keyword network analysis and topic modeling offers a replicable approach for tracking research trends in rapidly evolving interdisciplinary fields.
