  • Identification of bitter receptors for hydrolyzed soy protein
    Patent number: 7794959
    Abstract: The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in hydrolyzed soy protein derived materials. The invention further relates to the use of these T2R receptors in assays for identifying ligands that modulate the activation of these taste receptors by specific bitter ligands present in hydrolyzed soy protein materials and derivatives thereof and related compounds. These compounds may be used as additives and/or removed from soy-based foods, beverages, cosmetics and medicinals in order to modify (block) T2R-associated bitter taste elicited by bitter ligands present in hydrolyzed soy protein materials.
