Abstract
A D-tagatose spray-drying feed formulation is a mixture of D-tagatose and a functional excipient co-dissolved in a solvent to produce a excipient/D-tagatose composite having a glass transition temperature of greater than 30° C. A method of spray-drying D-tagatose includes the steps of (a) preparing the D-tagatose spray-drying formulation, (b) atomizing the D-tagatose spray-drying formulation in a drying chamber containing a hot inert processing gas and evaporating droplets to produce solid particles of excipient/D-tagatose composite and (c) separating and collecting the solid particles of excipient/D-tagatose composite from the processing gas.
Claims19
A D-tagatose spray-drying feed formulation, comprising:
