Contribution analysis of sensory cues to oil/fat perception
Oil/fat perception is an important subject of food science research. Various scientific theories have risen over the years about the mechanisms of oil/fat perception, but fundamental knowledge is still lacking. In particular, the dominating sensory cue(s) eliciting oil/fat perception is still up to debate in literature. In this study, 30 participants were recruited to test six samples (three natural oil/fats and three constituted) using three senses (smell, taste, and tactile). Responses showed that natural oil/fats were perceived as such with multimodal way of sensing. Texture and aroma cues played a bigger role compared to taste. Our findings suggest that aroma and texture and multimodal sensation are the mechanisms of oil/fat detection, while taste alone did not illicit sensations of oil/fat. Practical Applications Information provided here deals with contribution of different senses to six model compounds, giving new insight for human oil/fat perception. We consider these findings important for food scientists working in academia and industry alike. In order to keep consumer sensory satisfaction, food containing oil/fat must be designed to elicit preferable sensory responses. Our experiments were on model compounds, but when dealing with other food types either emulsions or liquid food matrices containing fat will be perceived in a similar manner.
