The present invention relates to a process for preparing a polysaccharide gelled foam comprising the following steps: a. preparing a mixture comprising: - at least one dissolved polysaccharide chosen from alginates, pectic substances, carrageenans, and mixtures thereof, - at least one solvent of said polysaccharide, - at least one ionic crosslinking agent for crosslinking said polysaccharide, said crosslinking agent being unavailable - optionally a plasticizer soluble in said solvent, - optionally a surfactant, and - optionally an additive, b. foaming and gelling said mixture prepared in step a. by incorporating a pH-modifying gas, and c. optionally drying the gelled foam obtained in step b. The invention also relates to the gelled foam obtained from such a process and also to the uses thereof. |
