So it's probably the actions of cyclamate at
saccharin's
bitter receptors that help block the bitterness, Behrens and his colleagues report September 14 in Cell Chemical Biology.
In this case, though, the amount of
saccharin required to block the receptors that cyclamate activates would have
bitter effects on its own.
So with cyclamate around,
saccharin can't get at the
bitter taste subtypes, Behrens explains.
It turns out that
saccharin doesn't just activate sweet taste receptors, it also blocks
bitter ones — the same
bitter taste receptors that cyclamate activates.
The reverse was true, too:
Saccharin blocked TAS2R1 — one of the
bitter receptors that cyclamate activates.
Behrens and his colleagues Kristina Blank and Wolfgang Meyerhof developed a way to screen which of the
bitter taste receptors that
saccharin and cyclamate were hitting, to figure out why the combination is more palatable than either one alone.
Compounds like
saccharin are potent sweeteners, but new research suggests they could be a
bitter pill for some gut microbes.
Saccharin and cyclamate both have
bitter ends.
So with cyclamate around,
saccharin can't get at the
bitter - taste receptors it normally triggers, Behrens explains.
Blends of non-caloric sweeteners
saccharin and cyclamate show reduced off - taste due to TAS2R
bitter receptor inhibition.
It also blocks the
bitter receptors that
saccharin stimulates.
Previous studies of the two sweeteners had shown that
saccharin activates the
bitter receptor subtypes 31 and 43.
