Advice on forming a 10% solution of Maltol
Maltol (3-Hydroxy-2-methyl-4-pyrone) appears to be most soluble in ethanol.
https://pubchem.ncbi.nlm.nih.gov/compound/maltol#section=Melting-Point gives solubility as
1 to 10 mg/mL at 72° F in water, 10900 mg/L at 15 deg C (about 1%); one gram dissolves in 82 mL water, 80 mL glycerin, 21 mL alcohol, 28 mL propylene glycol; Freely soluble in hot water, chloroform; sparingly soluble in benzene, ether, petroleum ether; soluble in alkali hydroxides giving yellow solutions

Your fluffy floating clumps suggest something like water, which would reduce the solubility of maltol and could clump it up. or maybe there is some other impurity that complicates things.

You could try is to make a 5% solution in warm dry ethanol (apparently no problem...) and then evaporate off excess solvent. If you can get 10% when hot, but the solution drops crystals on cooling, you will have a saturated solution. But maybe it won't precipitate...
