Does the lingual film intervene in the perception of taste?

International audience; The biological film at the surface of the tongue, composed of saliva and microorganims, is an important interface between exogenous taste molecules and receptors involved in taste perception. However, the relationships between the composition of the lingual film and the perception of taste are not fully described. Thus, the aim of the present work was to study the differences in the biochemical (protein concentration, metabolite profiles) and microbiological compositions of the tongue films from 20 adult subjects, and to explore the possible relationships between composition and taste sensitivity assessed by means of a rapid at-home test. Preliminary results showed t…
