Pungency is an interesting sensory stimulus analyzed from different perspectives, in particular the underpinning mechanisms of its sensation and perception. In this study, grilled pork meat coated with three types hot sauces were investigated regarding main food oral processing characteristics evaluated using time-intensity temporal dominance pungency sensations methods analyzing descriptors intensities. Besides these methods, facial expressions obtained video capturing subject to emotion detection. Mastication parameters showed a slight, but not statistically significant, trend increased number chews consumption time associated intensity, while saliva incorporation indicated increasing depending on especially after 25 strokes before swallowing. Both intensity that complexity understanding relation type. Finally, use detection software faces panelists during mastication confirmed increase non-neutral emotions intensity.
