Abstract: With the exposure of a series of online takeout food safety incidents, takeout food safety has attracted extensive attention from all walks of life.Based on the grounded theory, this paper encodes three levels of consumer comment data of various online platforms related to takeout, trying to find out all kinds of factors affecting takeout food safety, and uses structural equation model to analyze the mechanism of these factors.Four core categories and eight main model factors are found to solve the impact factors of takeout food management. The core categories of takeout platform, takeout merchants, government supervision and media supervision (both of which are combined into environmental factors) have a positive impact.Environmental factors have a common and prominent influence on other factors, so they are also the leading factors of the core factors of takeout food safety management.

Key words: takeout food, food safety, grounded theory, structural equation model
