Abstract: A protein-free soluble foaming composition is provided which contains carbohydrate particles having a plurality of voids containing entrapped pressurized gas. The composition may include a surfactant and may be contained in a food product such as a beverage mix or an instant food. In addition, a method is provided for manufacturing the foaming composition in which the protein-free soluble foaming particles are heated and an external pressure exceeding atmospheric pressure is applied to the protein-free soluble foaming particles. The soluble foaming particles are cooled and the external gas pressure is released resulting in pressurized gas remaining in internal voids of the foaming composition.

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.
