Consumers are directly and indirectly responsible for a significant fraction of food waste which, for a large part, could be avoided if they were willing to accept food that is suboptimal, i.e., food that deviates in sensory characteristics (odd shape, discoloration), or that has a best-before date which is approaching or has passed, but that is still perfectly fine to eat. The choice to accept or discard suboptimal food is taken either before or after purchase (hence, in the retail store or in the household). The aim of the European research project COSUS (Consumers in a sustainable food supply chain) was to increase consumer acceptance of suboptimal food, before and after purchase, by implementing targeted strategies that are based on consumer insights, and that are feasible for and acceptable by the food sector. To reach this aim, different methodological approaches were applied to analyze this issue, to experiment with different aspects, and to test the resulting interventions. Each of these approaches was undertaken by competent consortium partners from Denmark, Germany, Norway, Sweden and The Netherlands. The project finally provides validated strategies to promote the distribution and consumption of suboptimal foods, thereby improving resource efficiency in the food chain and contributing to a more sustainable food supply.
消费者直接或间接导致了相当一部分食物浪费。如果他们愿意接受次优食品，即在很大程度上这些浪费是可以避免的。次优食品是指在感官特性上有所偏差（形状怪异、变色），或者保质期即将到期或已过，但仍完全可以食用的食品。接受或丢弃次优食品的选择在购买之前或之后做出（即在零售店或家庭中）。欧洲研究项目COSUS（可持续食品供应链中的消费者）的目标是，通过实施基于消费者洞察、对食品行业可行且可接受的有针对性策略，提高消费者在购买前和购买后对次优食品的接受度。为实现这一目标，采用了不同的方法来分析这个问题、对不同方面进行试验，并测试由此产生的干预措施。丹麦、德国、挪威、瑞典和荷兰的相关联盟合作伙伴分别采用了这些方法。该项目最终提供了经过验证的策略，以促进次优食品的分销和消费，从而提高食品链中的资源效率，并有助于实现更可持续的食品供应。
