There is a paucity of research on the role of food delivery apps (FDAs) in food waste generation. This gap needs to be addressed since FDAs represent a fast-growing segment of the hospitality sector, which is already considered to be a key food waste generator globally. Even more critically, FDAs have become a prominent source of ordering food during the COVID-19 pandemic. In addition, the growing usage of FDAs warrants an improved understanding of the complexities of consumer behavior toward them, particularly during a health crisis. The present study addresses this need by examining the antecedents of FDA users’ food ordering behavior during the pandemic that can lead to food waste. The study theorizes that hygiene consciousness impacts the enablers and barriers to FDA usage, which, in turn, shape the attitude toward FDAs and the tendency to order more food than required, i.e., shopping routine. The conceptual model, based on behavioral reasoning theory, was tested using data collected from 440 users of FDAs during the pandemic. The results support a positive association of trust and price advantage with attitude, but only of trust with shopping routine. Perceived severity and moral norms did not moderate any associations.

关于食物递送应用程序（FDA）在食物垃圾产生中的作用的研究很少。由于FDA代表了酒店业的快速增长部分，因此需要解决这一差距，而FDA已经被认为是全球主要的食物垃圾产生者。更重要的是，在COVID-19大流行期间，FDA已成为订购食物的重要来源。此外，越来越多的FDA使用使人们更加了解消费者对其采取的行为的复杂性，尤其是在健康危机期间。本研究通过检查可能导致食物浪费的大流行期间FDA用户的食物订购行为的前因，来满足这一需求。该研究从理论上讲，卫生意识会影响FDA使用的推动力和障碍，而这反过来又会影响FDA的使用。塑造对FDA的态度以及订购更多食品的趋势，例如购物习惯。基于行为推理理论的概念模型已使用大流行期间从440名FDA使用者收集的数据进行了测试。结果支持信任和价格优势与态度之间的正相关关系，但仅与购物习惯有关。感知到的严厉程度和道德规范并未节制任何关联。
