1. A method for producing a dried protein-containing composition, the method comprising:
introducing a heat-sensitive protein composition into a drying chamber, wherein the heat-sensitive protein composition comprises water and one or more proteins;
drying the heat-sensitive protein composition by contacting the heat-sensitive protein composition with a pulsed gas stream of a pulse combustion dryer;
controlling the drying chamber outlet temperature such that the temperature of the heat-sensitive protein composition exceeds but does not substantially exceed a denaturation temperature of one or more proteins in the heat-sensitive protein composition; and
recovering a dried protein-containing composition.
