How about precipitating the sucrose? Acetone and CaCl2 can precipitate up to 98% of the sucrose. There are other precipitation schemes on the web that use complex organic compounds of transition metals, but they seem more useful for analyses than for actual separation. I can't do any better than to copy and paste an abstract (the whole article is available ...

If the amount of sugar is to be determined precisely in a given solution, the simplest thing is to mix it with a $0.2$ M $\ce{HCl}$ solution, to heat it up to boiling for ten minutes, and cooling it down to room temperature. This will hydrolyze the saccharose to a mixture glucose + fructose. Then, the glucose is determined by Fehling's solution, producing a $... 3 Magnesium ʟ-threonate has the molecular formula$\ce{C8H14MgO10}$with the molar mass$M = \pu{294.5 g mol^-1}$. Magnesium molar mass is about$\pu{24.9 g mol^-1}$. Magnesium ʟ-threonate has then percental magnesium content $$\displaystyle\frac{\pu{24.9 g mol^-1}}{\pu{294.5 g mol^-1}} \times 100\,\% = 8.46\,\%,$$ what gives for$\pu{2000 mg}\$ of magnesium ʟ-...
