A process for recovering odorous compounds from a gas originating from a process for treating a food product, comprising the step of adsorbing the odorous compounds on at least one solid food matrix by direct contact of the solid matrix with the gas. An apparatus is also provided which is adapted to conduct the described process and comprises a chamber which contains a gas originating from a process for treating a food product, evacuation means for emptying the chamber of the gas that arrives from a treatment process, and at least one adsorption column, which contains at least one solid food matrix and is connected pneumatically to the chamber so as to receive at least the odorous compounds contained in the gas originating from a treatment process and evacuated from the chamber by way of the evacuation means. L'invention concerne un procédé d'élimination de composés malodorants d'un gaz provenant d'un procédé de traitement d'un produit alimentaire, ledit procédé d'élimination comprend l'étape d'adsorption des composants malodorants sur au moins une matrice alimentaire solide par un contact direct de la matrice solide avec le gaz. Un appareil est également proposé qui est conçu pour conduire le procédé décrit et qui comprend une chambre qui contient un gaz provenant d'un procédé de traitement d'un produit alimentaire, des moyens d'évacuation pour vider la chambre du gaz qui est issu d'un procédé de traitement, et au moins une colonne d'adsorption, qui contient au moins une matrice alimentaire solide et est raccordée pneumatiquement à la chambre de sorte à recevoir au moins les composés malodorants contenus dans le gaz provenant d'un procédé de traitement et évacués de la chambre par les moyens d'évacuation.
