•This study examines the role of risk preferences in consumers’ WTPs for functional food.•Consumers are revealed to be reluctant to pay for functional milk.•Consumers with high-risk preferences are more willing to purchase functional milk.•Visual attention is positively correlated with consumers’ consumption preferences.•Consumers’ risk preferences should be considered when promoting functional food. With the prominence of nutrition-related health issues worldwide, functional food is supposed to be an efficient way to address this challenge by achieving its nutrition and health benefits. However, whether consumers are willing to pay (WTP) for high-nutritional value foods of this kind and what is the role of consumers’ risk preferences in their WTPs are unclear. This study employs a discrete choice experiment (DCE) to investigate the effect of risk preferences on consumers’ preferences and WTPs for functional food, focusing on four attributes of dairy products: origin, organic label, functionality and price. We also seek to understand the physiological mechanisms underlying this effect by a lab experiment using eye-tracking technology. The results show that consumers have various preferences and WTPs for different attributes of milk, but they are reluctant to pay for functional milk. Compared to consumers with low-risk preferences, consumers with high-risk preferences are more willing to purchase functional milk. The evidence from eye-tracking experiments indicates that visual attention to the attributes considered positively correlates with their consumption preference. Consumers with high-risk preferences tend to pay more attention to the functional attribute and therefore have a higher probability of purchasing functional milk. This study implies that consumers’ risk preferences should be considered when promoting consumers to purchase functional food, as different consumers have significantly distinct preferences.
