This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using localfoods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and webdocuments before (from January 2016 to December 2019) and after (from January 2020 to November 2022) the COVID-19 outbreak. TF-IDF analysis showed that ‘Trend’, ‘Market’, ‘Consumption’, and ‘Food service industry’ were the majorkeywords before the COVID-19 outbreak, whereas ‘Wanju-gun’, ‘Distribution’, ‘Development’, and ‘Meal-kit’ were mainkeywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after theCOVID-19 outbreak, the ‘Market’ category included ‘Non-face-to-face market’ instead of ‘Event,’ and ‘Delivery’ instead of‘Distribution’. In the ‘Product’ category, ‘Marketing’ was included instead of ‘Trend’. Additionally, in the ‘Support’ category,‘Start-up’ and ‘School food service’ appeared as new topics after the COVID-19 outbreak. In conclusion, this study showedthat meaningful change had occurred in market issues on HMR using local foods after the COVID-19 outbreak. Therefore,governments should take advantage of such market opportunity by implementing policy and programs to promote thedevelopment and marketing of HMR using local foods.
