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.

What is claimed is: 1. A method for manufacturing a powdered soluble foaming composition comprising amorphous particles having atmospheric pressure gas held in internal voids of the composition which are open to the atmosphere, said method comprising: applying an external gas pressure to a powdered soluble spray-dried composition comprising amorphous particles having sealed vacuous internal voids, while the amorphous particles are in a rigid glassy state at a temperature below the glass transition temperature of the particles, to thereby open at least a portion of the sealed voids to the atmosphere; and depressurizing the composition comprising the rigid glassy state amorphous particles, to thereby result in opened voids which hold external gas while not entrapping the external gas in the composition, wherein the entrapped gas is unable to leave without dissolving the composition in a liquid and the held gas is able to leave without dissolving the composition in a liquid. 2. The method of claim 1, wherein the external gas pressure is at least about 200 psi. 3. The method of claim 1, wherein said external gas pressure is at least about 500 psi. 4. The method of claim 1, wherein said external gas pressure is at least about 1000 psi. 5. The method of claim 1, wherein said external gas pressure is applied for at least about 1 second. 6. The method of claim 1, wherein said external gas pressure is applied for at least about 1 minute. 7. The method of claim 1, wherein gas used to effect said external gas pressure is a gas selected from the group consisting of air, nitrogen, carbon dioxide, nitrous oxide, and mixture thereof. 8. The method of claim 1, wherein said spray-dried composition is protein-free. 9. The method of claim 8, wherein said spray-dried composition comprises a dispersed fat. 10. The method of claim 8, wherein said spray-dried composition comprises a carbohydrate. 11. The method of claim 10, wherein said spray-dried composition further comprises a surfactant. 12. The method of claim 11, wherein said surfactant is an emulsifier. 13. The method of claim 12, wherein said emulsifier is selected from the group consisting of a polysorbate, sucrose ester, stearoyl lactylate, mono/di-glyceride, diacetyl tartaric ester of mono/di-glycerides, phospholipid, propylene glycol alginate, lipophilic modified starch, or mixture thereof. 14. The method of claim 1 wherein said spray-dried composition is carbohydrate-free. 15. The method of claim 14, wherein said spray-dried composition comprises a protein. 16. The method of claim 14, wherein said spray-dried composition comprises a dispersed fat. 17. The method of claim 14, wherein said spray-dried composition further comprises a buffering agent. 18. The method of claim 17, wherein said buffering agent is a salt of an organic or inorganic acid. 19. The method of claim 18, wherein said salt is selected from the group consisting of a sodium salt, potassium salt, magnesium salt, or calcium salt, of citric acid, fumaric acid, malic acid, phosphoric acid, or mixture thereof. 20. The method of claim 1, wherein said spray-dried composition comprises a dispersed fat. 21. The method of claim 1, wherein said composition has an internal void volume of at least about 10% before subjecting to the external gas pressure. 22. The method of claim 1, wherein said particles have an internal void volume of at least about 30% before subjecting to said external gas pressure. 23. The method of claim 1, wherein said particles have an internal void volume of at least about 50% before subjecting to said external gas pressure. 24. The method of claim 1, wherein said composition contains atmospheric pressure gas in an amount sufficient to release at least about 2 cc gas per gram of said foaming composition when dissolved in liquid at ambient conditions. 25. The method of claim 1, wherein said composition contains atmospheric pressure gas in an amount sufficient to release at least about 5 cc gas per gram of said foaming composition when dissolved in liquid at ambient conditions. 26. The method of claim 1, further comprising cooling the soluble spray-dried composition from a heated temperature below the glass transition temperature. 27. The method of claim 26, wherein said cooling is conducted prior to depressurizing the composition. 28. The method of claim 26, wherein said cooling is conducted while depressurizing the composition. 29. The method of claim 26, wherein said cooling comprises cooling the composition from heated to below the glass transition temperature to about room temperature. 30. The method of claim 1, wherein said applying external pressure is conducted while applying heat to the composition. 31. The method of claim 1, wherein said applying heat is conducted prior to applying external pressure to the composition. 32. The method of claim 1, wherein said spray-dried composition is formed via gas-injected spray drying of an aqueous solution. 33. The method of claim 1, further comprising gas-injected spray-drying of an aqueous solution to form the composition with particles having internal voids. 34. The method of claim 33, wherein gas used in said gas-injected spray-drying is selected from the group consisting of air, nitrogen, carbon dioxide, nitrous oxide, and mixture thereof. 35. The method of claim 1, further comprising non-gas-injected spray-drying of an aqueous solution to form the composition with particles having internal voids. 36. The method of claim 1, wherein the applied external gas pressure is sufficient to form stress cracks in the soluble spray-dried composition which is in the form of glassy amorphous particles. 37. A method for manufacturing a powdered soluble foaming composition comprising amorphous particles having internal voids filled with atmospheric pressure, said method comprising: applying an external gas pressure to a powdered soluble spray-dried composition comprising amorphous particles having vacuous internal voids, at a temperature below the glass transition temperature of the particles and which is between 20° C. and 60° C., wherein the external gas pressure is sufficient to form stress cracks in the soluble spray-dried composition which is in the form of glassy amorphous particles; and depressurizing the composition to thereby result in at least a portion of vacuous internal voids of the composition being open to the environment, wherein the internal voids hold external gas while not entrapping the external gas, wherein the entrapped gas is unable to leave without dissolving the composition in a liquid and the held gas is able to leave without dissolving the composition in a liquid. 38. A method for manufacturing a powdered soluble foaming composition comprising amorphous particles having atmospheric pressure gas held in internal voids of the composition which are open to the atmosphere, said method consisting of: applying an external gas pressure to a powdered soluble spray-dried composition comprising amorphous particles having sealed vacuous internal voids, while the amorphous particles are in a rigid glassy state at a temperature below the glass transition temperature of the particles, to thereby open at least a portion of the sealed voids to the atmosphere; and depressurizing the composition comprising the rigid glassy state amorphous particles, to thereby result in the opened voids being filled with held atmospheric pressure gas, wherein the held gas is able to leave without dissolving the composition in a liquid. 39.
