The present invention relates to a method for preparing a non-hygroscopic pulverulent composition comprising a step of spray drying, without atomization support, of an aqueous solution containing at least one initially hygroscopic product, having a glass transition temperature of 10. degree C at 110 degree C, and a cryogenic fluid, especially a cryogenic food fluid, or a mixture of cryogenic fluids, especially selected from carbon dioxide, nitrogen, liquid air, said aqueous solution being obtained by dissolving said cryogenic fluid in an initial aqueous solution containing said initially hygroscopic product. |
