The increase in the global sugar-free trend and interest in sugar-free products has resulted in most consumers becoming more interested in products with low or no sugar content. This study explored consumer perceptions of sugar-free products through text network analysis using big data. After collecting the texts, 50 key words were extracted through frequency analysis and TF-IDF analysis. Subsequently, they were categorized into four clusters using degree centrality analysis, social network analysis, and CONCOR analysis, to arrive at the implications. The limitations of the study were then listed.
