Somach genius here!

Please tell me why only water dissolved molecules can get to taste... if we
somehow supply right form of the molecule in dry conditions...it will give some taste...if the receptor is in right form, of course!!!

NOw, evolutionarily... most pleasuregiving taste is to be of the most required [ in amount and also vital] thing/s...
so is fructose...

similarly u can think about hot to bitter tasting things...


excuse my English evn if it tastes stupid :lol:

Not only water dissolved molecule have a taste. I have put some chili oil on a pizza, and the capsaicine was not dissolved in water, but it was well...a little overwhelming.

So why liquid molecules, probably because the probability of contact between a receptor and a solute are higher than that of a solid which will always be giantic at the molecular level.

First, the technical stuff: the tongue contains many many flavor receptors, some of which are specific for sugar molecules. When sugar hits the tongue, the molecules bind to the sugar receptors, and the receptor triggers a nerve impulse which travels to the brain and says, "sweet." Because these sugar receptors only recognize a part of the sugar molecule, they are easily fooled by other molecules which have this piece of the sugar molecule; this is why saccharine and aspartame taste sweet.

But why go to the trouble of telling your brain, "sweet," whenever you eat sugar? Sugar in the simplest form of carbohydrate and, as such, is the best source of energy for the body to consume. So, the taste system was developed to tell the brain when "good food" was around, so that you would know to eat lots of it. We describe the brains view of "sugar is good" as "sweet".

ah, then it means that my brain is wrong in function then...because my brain said that it's delicious when I drink a very bitter tea...:lol:

perhaps it is because u are too old,

and do not need too much carb.

however, notice that sweets thing have a universal appeal in young children

Naah..I think I got the same age as you...I'm just 18 since last 2nd April..:lol:
And, this implies that 'good food' or 'good drink' is depend on our perception...tastes only give their message as electrical impulses. The rest?it's up to us, what are we going to say whether it's good or bad..:lol:

that's still too old. my point is as children, we tend to like sweet things like sugar, because that is the way our brain tell us to eat more of it. because it is good for you as energy source to help us grow. this may change after we grow up.
in principle of course, human taste buds should be the same for everyone. it is the brain that actually determine whether we like or dislike the food.

and the main reason for the different perception of food is that people tend to like the taste of foods that they grew up with. for example, in india, people are accustomed to hot food, and in some parts of europe, lots of cheese,

That was a pt. keikyon , but if we grow up one from Victoraceae [ people like victor who like bitter] in just the minimal medium of bitter-tea
]only[ He will not say tea is sweat immediately in the next generation.He will die!!! ANd bitterliking[Victoraceae] people will go on eating bitters even if sweets are available and then will be naturally eliminated thru the agency of natural selection.
So for sugars perception has been naturally selected to be sweet as calling it sweet is key to survival in most places! But for edibles that have got less imp. the persons simply liking the material available to them can use the available materials more efficiently as liking them will increase the collection and eating of the liked food and thus are selected. So we like what we greew up with.

Did you grow up in a teapark victor?
Or the tea has done sort of BLAcK MagiK on you!!!

don't be that extreme like that 2810712, even till naming me Victoraceae..:lol: I like that name though..:lol:
I don't know..I just like to drink tea, maybe because its bitter taste keep relaxing me (and after that it's caffeeine will keep me awake..:lol:) so I call it 'sweet'...'so sweet'...hahaha..:lol:
