Developing Multimodal Food Augmentation Techniques to Enhance Satiety

Abstract: In the contemporary food landscape, where easily accessible and appetizing food options prevail, the issue of overconsumption and its contribution to global obesity concerns remains a critical societal and research challenge. While it is well-established that sensory appeal plays a key role in motivating eating behaviour, recent studies have underscored the direct impact of sensory properties on food consumption, mediated by internal signals like hunger and satiety. Among the various sensory factors influencing eating behaviour, two phenomena have garnered significant scientific interest: sensory-specific satiety (SSS) and sensory-specific appetite (SSA). In this research we aim to explore if augmenting food products through visual, olfactory, and haptic feedback can change eating behaviour and affect SSA or SSS. To further expand our understanding of these phenomena, this study employs a novel system utilizing multimodal augmentation of plant and meat-based products consumed in a controlled environment.
