Date labels have been implicated as a driver of premature discard of food by consumers, which has led to recommendations to change date labels as a way to reduce food waste. However, most proposed date label reform has focused on changing the phrase that accompanies the date on the label, and not how the date is selected. To explore the relative importance of these date label elements, we track consumers' eye movements when evaluating milk container images. When making decisions about the possible discard of milk, participants fixate significantly more on the date printed on the container than on the phrase (e.g., "use by") with >50% of decisions involving no visual fixation on the phrase. This relative inattentiveness to phrases suggests regulation of food date labels should include more focus on the process of choosing label dates.
日期标签被认为是消费者提前丢弃食物的一个驱动因素,这导致了改变日期标签的建议,以此作为减少食物浪费的一种方式。然而,大多数提议的日期标签改革都集中在改变标签上日期旁边的短语,而不是选择日期的方式。为了探索这些日期标签元素的相对重要性,我们跟踪消费者在评估牛奶容器图像时的眼球运动。在决定是否可能丢弃牛奶时,参与者将目光明显更多地集中在容器上打印的日期上,而不是印在标签上的短语(例如“使用期限”)上,超过 50%的决定没有对短语进行视觉关注。这种对短语的相对不关注表明,食品日期标签的监管应该更加关注选择标签日期的过程。
