Described herein are mammalian taste papillae cells, cell lines, and cell membranes, methods, and kits for identifying agents, including ligands for olfactory receptors and enhancers and blockers thereof, that bind to or modulate the activity of olfactory receptors on mammalian taste papillae cells.

Methods of identifying modulators of olfactory receptors

A composition comprising a bitter tastant and at least one sophorolipid and optionally a carrier; wherein the composition is edible and wherein the bitter taste of said bitter tastant is reduced. A method of reducing bitter taste attributed to a bitter tastant in an edible composition, said method comprising adding to said edible composition an effective amount of at least one sophorolipid and optionally a carrier; such that any bitter taste induced by the bitter tastant is reduced.

Compositions containing a bitter tastant and at least one sophorolipid, and methods of reducing bitter taste attributed to a bitter tastant in an edible composition

The invention provides methods of culturing mammalian taste cells, including taste receptor cells. Cells are maintained for a duration of up to three months and longer while maintaining molecular and functional characteristics of mature taste cells. The cells are cultured on coated cell culture vessels and, from first replacement of medium onwards, the medium is replaced in intervals of at least 5 days. The invention further provides isolation and culturing methods of taste cells wherein the time that the cells are exposed to isolation solution and proteolytic enzymes is minimized and the cells are cultured in coated culture vessels with the medium replaced in intervals of at least 5 days from first replacement onwards. The invention further provides cultured taste cells, transfection and assay methods, and taste cell assay buffers with an osmolarity of about 300-320 and pH of about 7.0-7.3.
