Food items are increasingly chosen based on sustainability attributes as the public is becoming increasingly aware of the environmental and animal welfare impacts of production systems, in addition to the traditional consideration for nutrition. Although surveys have been used to investigate the demand for these attributes in unprocessed products, little information exists on how these attributes impact consumer preferences in the case of processed products or prepared meals. This study uses a stated preference survey to examine Quebec (Canada) consumers' preferences for eggs from four production systems with different impacts on animal welfare and on the environment. We compare the respondents' choices of fresh eggs and two prepared meals that contain eggs. Furthermore, we examine the shift in choices following information treatments on animal welfare, nutrition, or environmental impact attributes. Results indicate that respondents choose eggs from more sustainable production systems more frequently when included in prepared meals than in their unprocessed form. The provision of information led participants to update prior beliefs and revise their initial choices, especially for animal welfare attributes.
由于公众除了对传统的营养因素加以考虑外,越来越意识到生产系统对环境和动物福利的影响,食品的选择越来越多地基于可持续性属性。尽管已有调查用于研究未加工产品对这些属性的需求,但对于这些属性如何影响加工产品或预制餐食的消费者偏好,却几乎没有相关信息。本研究采用陈述偏好调查,来考察魁北克(加拿大)消费者对来自四种不同生产系统的鸡蛋的偏好,这些生产系统对动物福利和环境有着不同影响。我们比较了受访者对新鲜鸡蛋以及两种含鸡蛋的预制餐食的选择。此外,我们还考察了在提供有关动物福利、营养或环境影响属性的信息后,受访者选择的变化情况。结果表明,当鸡蛋以预制餐食形式出现时,相较于未加工形式,受访者更频繁地选择来自更具可持续性生产系统的鸡蛋。信息的提供促使参与者更新先前的观念,并修正他们最初的选择,尤其是对于动物福利属性。
