A coffee aroma such as a coffee aroma frost is contacted with a volatile organic carrier liquid at a processing temperature at which the carrier is in the liquid state and at which any moisture present is in the form of ice, to effect fixation of the aroma into the carrier liquid. The carrier liquid has a freezing point below the processing temperature, a boiling point above the processing temperature, a vapor pressure of at least 0.01 mm Hg at 25 ~C and atmospheric pressure, and a water solubility of not more than 10 % by weight.

L'invention concerne un procédé permettant de préparer des compositions d'aromatisation du café. Ce procédé consiste à faire entrer en contact un arôme de café tel qu'un arôme de café sous forme gelée, avec un véhicule liquide organique volatil, à une température de traitement à laquelle le véhicule se trouve à l'état liquide et toute humidité présente est gelée, afin de permettre à l'arôme de se fixer dans le véhicule liquide. Le véhicule liquide présente un point de congélation inférieur à la température de traitement, un point d'ébullition supérieur à la température de traitement, une pression de vapeur d'au moins 0,01 mm Hg à 25 ·C et à pression atmosphérique, et une solubilité dans l'eau ne dépassant pas 10 % en poids.
