Malleability of food values amid the COVID-19 pandemic
研究对比了疫情前后消费者对食品价值的重视程度，发现食品安全重要性下降，而口味、营养等重要性上升，且变化因人群而异。
Abstract Food values are supposed to be stable. This paper tests this assumption by comparing food values before and during the coronavirus-19 pandemic. While the ranking of food values remains very similar, there are some interesting differences in the relative importance that consumers attached to food values before and during the pandemic. A substantial decrease in the importance that consumers attach to food safety was observed during the pandemic, while there was a moderate increase in the importance attached to taste, nutrition, appearance, convenience and origin. The changes in food values vary across sociodemographic groups. Implications of the results are discussed.
