A method for preparing an aromatic pulverulent composition having a melting point Tf, comprising: i) feeding at least two pulverulent elementary solids having organoleptic properties into a mixer, whose chamber has been preheated beforehand to a temperature T lower than Tf, such solids being separately fed into the mixer; ii) mixing the pulverulent elementary solids in the mixer, in the absence of any external liquid phase, at a temperature T lower than Tf, at least one of the pulverulent elementary solids being fed into the mixer at a temperature Ti, such that the mixing occurs under isothermal conditions at a temperature set at such temperature T; and iii) recovering the aromatic pulverulent composition. This method is particularly suitable for preparing a composition essentially including a vanillin and ethylvanillin compound.

Method for preparing an aromatic composition including a compound containing two solids having organoleptic properties

A compound that includes vanillin and ethylvanillin, and a method for making same are described. The compound described can be obtained by the co-crystallization of vanillin and ethylvanillin. Methods of using the compound in numerous applicable fields, particularly in human and animal food are also described.
