Abstract
A method is provided for producing a powdered soluble foaming composition comprising amorphous particles having internal voids filled with atmospheric pressure gas. The method includes subjecting a spray-dried composition to an external pressure and heating the composition at a temperature below the glass transition temperature. The composition is depressurized to result in at least a portion of vacuous internal voids of the composition to be filled with atmospheric pressure gas.

A method for manufacturing a powdered soluble foaming composition comprising amorphous particles having internal voids filled with atmospheric pressure gas, said method comprising:
- applying an external gas pressure to a powdered soluble spray-dried composition comprising amorphous particles having vacuous internal voids;
- heating the soluble spray-dried composition at a temperature below the glass transition temperature;
- and
- depressurizing the composition to thereby result in at least a portion of vacuous internal voids of the composition to be filled with atmospheric pressure gas.
