Abstract
Methods for pulse combustion spray drying of heat-sensitive protein compositions using high temperature pulsating jets to atomize and dry the feed simultaneously are described herein. Methods and compositions described herein provide dried protein-containing compositions with low protein denaturation and other useful functional properties at high operational efficiencies.
Claims13
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.
