How do you remove sugar from orange juice or other liquid juices without evaporation?

Question

how do you remove both natural and artificial sugar from juice.

Answer 1

The nutritionist answer would be to avoid the juices and eat whole fruit, as the whole fruit would be lower on the glycemic index. 

Most low sugar or sugar free juices on the market are likely made with very small amounts of the actual juice, then highly diluted and fortified with artificial sweeteners and synthetic vitamins, which is fine. I just drank one right now. So you could always do that. I am sure they sell drink mixes that accomplish similar things. Unless you desire to feel like you are drinking actual juice without the sugar. 

That being said, there is no way to do what you are asking unless you have an organic lab at your disposal. Fermenting the sugars and evaporating the alcohol and filtering the yeast (or whatever microorganism you used to filter) is possible, but the resulting beverage would probably be exceedingly acidic and undrinkable, and probably contaminated by congeners besides residual alcohol compounds (which will never all be removed, unless all the water is gone as well, which would make it more of a paste, or a powder, or a hard chunk of carbon...)

 

Maybe you can try fermenting it, filtering it, evaporating in a double boiler, grinding the residual solid and then reconstituting it with water. That might be possible, but certainly time consuming.

 

Though there are certainly polarity differences between carbohydrates (like fructose and glucose and glucose-fructose) and amino acids (like water soluble vitamins and pigments) I dont believe they are different enough to accomplish anything by solvent-solvent extraction.

 

Best move is to just buy a powdered drink/juice  mix that accomplishes what you desire. You could always mix some of the actual juice in there as well.  Or, as suggested, you could get used to drinking more dilute juices. Becoming accustomed to the lower sweetness would likely not hurt you in the long run.

 

What about mixing a soluble fiber with your juice to lower the G-I by slowing absorption/reducing insulin response? Or even juicing your own fruits with a mix of veggies and fruit and adding some soluble fiber and making sure that the fibrous remnants of the fruits is re-blended into the juice.

 

Anyway, happy hunting. I found this when I was curious how my "fitnllean" pom juice had such low sugar. my guess is it was diluted, artifically sweetneed and fortified.

Answer 2

You could always ferment it :-)
