Since perishable food in private households is usually stored in refrigerators, both consumer knowledge of correct storage parameters and food handling have a major impact on food quality retention. Today's refrigerators provide features, such as climate-controlled compartments, to improve chilled storage performance, but former studies have shown a lack of usage and interest in such features. This paper is based on the results of an online survey with 2666 respondents from Germany. The questionnaire focused on consumer behaviour regarding the chilled storage of perishable foods, the perception of quality loss in food and consumer requirements concerning refrigerators. The novelty in the study layout was the focus on seven common refrigerator storage features. The results showed that consumers had a high awareness of food safety, resulting in short storage durations. While it was clearly indicated that the storage features were less well-known, their importance correlated with rates of food waste, underlining the potential for improvement. The survey implied that raising the awareness of storage climate parameters is a tool for nudging consumers into lower rates of food waste.
由于私人家庭中的易腐食品通常存放在冰箱中，消费者对正确储存参数的了解以及食品处理方式对食品质量的保持都有重大影响。如今的冰箱具备一些功能，如气候控制隔层，以提高冷藏性能，但先前的研究表明，消费者对这些功能缺乏使用和兴趣。本文基于对来自德国的2666名受访者进行的在线调查结果。问卷聚焦于易腐食品冷藏方面的消费者行为、对食品质量损失的认知以及消费者对冰箱的要求。该研究布局的新颖之处在于关注了七种常见的冰箱储存功能。结果显示，消费者对食品安全有很高的认知度，导致储存时间较短。虽然很明显储存功能不太为人所知，但其重要性与食物浪费率相关，这凸显了改进的潜力。该调查表明，提高对储存气候参数的认知是促使消费者降低食物浪费率的一种手段。
