Abstract
The present invention relates to a liquid composition which comprises, in an aqueous medium, one or more protein(s) and one or more solubilizing agent(s) chosen from the group consisting of anionic compounds of non-saccharide structure, said structure of which contains at least one aromatic nucleus comprising at least 6 ring members (6 atoms) and at least one carboxylic acid group in salified form, and which has, in its acid form, a molar mass of between 130 and 500 g/mol.It also relates to the use of said solubilizing agent(s) for preparing compositions according to the invention.It also relates to a process for solubilizing one or more protein(s), wherein at least one solubilizing agent chosen from the group consisting of anionic compounds of non-saccharide structure, said structure of which contains at least one aromatic nucleus comprising at least 6 ring members (6 atoms) and at least one carboxylic acid group in salified form, and which has, in its acid form, a molar mass of between 130 and 500 g/mol, is added to an aqueous protein preparation in order to solubilize the protein.
