This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using local foods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and web documents 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 major keywords before the COVID-19 outbreak, whereas ‘Wanju-gun’, ‘Distribution’, ‘Development’, and ‘Meal-kit’ were main keywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after the COVID-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 showed that 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 the development and marketing of HMR using local foods.
