Patent

CA 2612561

The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds, i.e., chlorogenic lactone compounds that contribute at least partially to the bitter taste of many coffee beverages. The present invention further relates to the use of these receptors in assays for identifying ligands that modulate the activation of these taste receptors by chlorogenic lactones and related compounds and which may be used as additives and/or removed from foods, beverages and medicinals in order to modify (block) T2R- associated bitter taste. A preferred embodiment is the use of the identified compounds as additives in coffee and coffee-flavored foods, beverages and medicinals.

Selon cette invention, il s'avère que des récepteurs humains du goût dans la famille des récepteurs du goût T2R réagissent à des composés amères particuliers, tels que des composés de lactones chlorogéniques, qui contribuent au moins partiellement au goût amère de nombreuses boissons à base de café. L'invention porte sur l'utilisation de ces récepteurs dans des dosages pour identifier des ligands qui modulent l'activation de ces récepteurs du goût par des lactones chlorogéniques et des composés correspondants et qui peuvent être utilisés comme additifs et/ou être éliminés des aliments, des boissons et des médicaments afin de modifier (bloquer) le goût amère associé à T2R. selon un mode de mise en oeuvre préféré, on utilise les composés identifiés comme additifs dans le café et dans des aliments aromatisés au café, des boissons et des médicaments à base de café.
