Why do sweeteners taste different to sugar?
« on: 16/02/2010 18:26:03 »
I was told once that sweeteners work because they trigger the same receptors as table sugar (sucrose).  My question is, if they trigger the same receptors then why do they taste so different?

Chris - We talked about Aspartame last week, and thatís about 200 times sweeter than sugar.  The reason that we use it, of course, is to make things taste much sweeter without having to add additional sugar - because the sweetener molecule has got virtually no calories in it compared to the large amount of calories that are in sugar.  It fools the tongue into thinking things taste sweet because it locks on to the same chemical receptor -  the docking station that recognizes sugar  - making it taste sweet.  In reality it doesnít actually impart any caloric contribution.  The reason that it also has other tastes is because it doesnít just recognize the receptor for sugar, it also binds to other flavour receptors as well.
