Defining core science of ‘sensory and consumer science’: Understanding human sensory perception, foods/materials interaction, and their influence on consumer behavior, health, and well-being

Jaeger et al.’s paper in 2025 addresses the evolving definitions of Sensory and Consumer Science, highlighting major shifts over time. They present a contemporary perspective based on survey data and invite further discussion. In response, this paper introduces and discusses key developments and definitions that have not been adequately addressed, including the evolving scope of Sensory and Consumer Science within the Asian region, particularly in South Korea. The definition of Sensory and Consumer Science should capture its uniqueness and the core scientific disciplines that enable it to develop as a coherent science. This paper argues that Sensory and Consumer Science should be recognized as an interdisciplinary and multidisciplinary science that systematically examines the interaction between human sensory perception and material stimuli, influencing consumer behavior, health, and well-being. To expand its global impact, Sensory and Consumer Science must be defined as a convergence science that integrates multiple disciplines such as psychology, cognitive science, neuroscience, nutrition, and materials science, promoting varying levels of interdisciplinary integration. A precise definition of its interdisciplinary scientific scope and methodologies is essential to ensuring its continued development. The South Korean case demonstrates how formal academic recognition at the national level establishes Sensory and Consumer Science as a structured and independent discipline. This recognition reinforces the importance of defining core interdisciplinary methodologies, securing future research, funding, and educational programs, and ensuring the field's long-term academic legitimacy.
