There is 1 problem with using hydrochloric acid as described before, Hydrochloric acid dehydrates most organic compounds and in stead of having a glucose solution after you are done you would have a solid carbon residue, e.g. you would make coal instead of C12H22O11

Glucose is solid, so you probably mean a solution of glucose in water, if you speak about liquid glucose.
If you really want to use an acid, in this case 0,1M hydrochloric acid should do it, then take a ceramic vessel with a heavy cover, put into it the starch powder, add water and stir it well, then add hydrochloric acid that it comes to a ph-value around 1 and keep the covered vessel in your oven at about 85°C for about 3 hours.
You have to make sure, that the vessel is really good covered; if acid vapour come out, your oven might suffer corrosion.
After this procedure you must neutralize the acid with soda, until adding soda doesn´t develop carbon dioxide gas anymore. Then you should have a liquid of pH around 7 which is tasting sweet from glucose.
And after that comes your genius of optimizing this recipe, because I only created it from a principal point of view. I never was cooking this lemonade myself yet. And if I had to do it, I wouldn´t use an acid but an enzyme in order to avoid the neutralization step.

yeah have fun ruining your oven. make sure the acid doesn't escape or you'll be screwed as you breathe it.
