1. A method of spray-drying D-tagatose, comprising:
preparing a D-tagatose spray-drying feed formulation consisting of a mixture of D-tagatose and a functional polymer excipient co-dissolved in a solvent to produce a functional polymer excipient/D-tagatose composite having a glass transition temperature of greater than 30° C.;
atomizing the D-tagatose spray-drying formulation in a drying chamber containing an inert processing gas and evaporating droplets to produce solid particles of D-tagatose; and
separating and collecting the solid particles of the functional polymer excipient/D-tagatose composite from the processing gas.
