How to remove caffeine or sugar from a beverage without destroying the caffeine or the beverage?

Question

How can you remove caffeine or sugar from a drink without destroying either product? E.g Removing caffeine from coke, with the end product being the caffeine and the coke in separate sections.

Answer 1

the only solution i can think of is add water.

Answer 2

You'd have to use a toxic organic solvent in which only the caffeine were soluble. I wouldn't recommend drinking the separated products, however.

Caffeine is removed from coffee beans using a supercritical fluid, but that requires expensive apparatus and wouldn't work with a complex mixture such as cola.

Answer 3

distill it

points plz

Answer 4

distillation will only separate the water from all the rest. Plus heating it to distill it will change the soda, for example removing the CO2.

Really can't do much.
