miracle berry, sweeten sour food without any sugar added

bird said:

Dried Miracle berry is now available for dieters, diabetics, and one
want to avoid sugar(white devil).

It's natural, safe and miracle. Just only one small pile make sour
food(i.e. lemonade, vinegar) become unbelieveable sweet for 1/2 to 1
hour.

So, what happens to the food after an hour? Does it self destruct?
Melt, like the Eicked Witch of the West? Fly away? I'm intrigued!!

Oh yeah - and why, exactly, would I want sweet vinegar?

usually use it to sweeten the sour food which you need to add sugar,
i.e. lemonade(or you drink it pure) . To sweeten a jar of lemonade, you
need about one and half cup of sugar!!! the white devil(it serious with
diabetics because sugar can cause several severe symptoms.)

Moreover,it is used to sweeten sour fruit, i.e. strawberry, plum.

Someone use it with vinegar with noodle. Chew miracle berry, order a
bowl of noodle and sweeten the noodle with vinegar.(better than to take
pure vinegar)
