THE INVENTION RELATES TO A METHOD FOR PREPARING AN AROMATIC POWDER COMPOSITION HAVING A MELTING TEMPERATURE TF, INCLUDING: I) FEEDING AT LEAST TWO BASIC POWDER SOLIDS HAVING ORGANOLEPTIC PROPERTIES INTO A MIXER, THE ENCLOSURE OF WHICH HAS BEEN PREHEATED TO A TEMPERATURE T LOWER THAN TF, SAID SOLIDS BEING SEPARATELY FED INTO SAID MIXER； II) MIXING SAID SOLIDS IN SAID MIXER, IN THE ABSENCE OF ANY OUTSIDE LIQUID PHASE, AT A TEMPERATURE T LOWER THAN TEMPERATURE TF, AT LEAST ONE OF SAID BASIC POWDER SOLIDS BEING FED INTO SAID MIXER AT A TEMPERATURE TI, SUCH THAT THE MIXING OCCURS UNDER ISOTHERMAL CONDITIONS AT A TEMPERATURE SET AT SAID TEMPERATURE T； AND III) RECOVERING SAID AROMATIC POWDER COMPOSITION. SAID METHOD IS PARTICULARLY SUITABLE FOR PREPARING A COMPOSITION ESSENTIALLY INCLUDING A VANILLIN AND ETHYLVANILLIN COMPOUND.
