The present invention relates to a method for texturing food and/or nutraceutical products of the "sponge cake" or "solid foam" type comprising at least: (a). A transformation by controlled grinding of a preparation of at least one food, able to preserve the desired organoleptic properties, able to obtain a ground material, (b). Addition of a molecule with an inactive structure to said ground material to obtain a mixture, (c). Pressurization of the mixture obtained in step (b) by the incorporation of dissolved gas into said mixture, (d). Mechanical expansion obtained by reducing the pressure of the mixture obtained in step (b), (e). Activation of the structure molecule, characterized in that the mechanical expansion is achieved by reducing the pressure by at least 6 bar, preferably between 6 and 20 bar, preferably between 10 and 18 bar.
