This research explores consumer perceptions of organic food across three distinct periods: Pre-COVID, during COVID, and Post-COVID. It examines how the pandemic shaped consumer behavior and preferences, especially on social media platforms, regarding organic food. By analyzing responses from 600,000 interactions across platforms like Twitter, Facebook, YouTube, and forums, the study offers valuable insights into evolving attitudes. This research is unique as it provides a comprehensive comparison of consumer sentiment across different pandemic phases, offering a detailed perspective on how health consciousness and organic food preferences shifted over time. The study’s innovative use of Latent Dirichlet Allocation (LDA) and perceptual map scores distinguishes it as a pioneering approach in the analysis of organic food trends during these critical periods. By capturing changes in sentiment and identifying key characteristics influencing consumer choices, the research highlights the increased preference for organic food during the pandemic due to health concerns and immunity needs. It also reveals a growing emphasis on supporting local farmers and sustainable food practices in the Post-COVID era. This study provides crucial insights for policymakers, marketers, and producers, emphasizing the need to adapt to these evolving consumer demands.
