The invention relates to a method for enzymatically preparing aromas, particularly C6 to C10 aldehydes, by contacting at least one source of lipoxygenase and hydroperoxyde-lyase with a source of unsaturated fatty acids, the reaction taking place under agitation conditions in the presence of oxygen, in a multiphase medium comprising at least one solid phase and one oily phase, characterized in that said medium comprises, per 100 parts of solid phase, approximately from 3 to 150 parts of an oily phase, and optionally approximately from 0 to 250 parts of an aqueous phase.
L'invention concerne un procédé de préparation par voie enzymatique, d'arômes, notamment d'aldehydes en C6 à C10, par la mise en contact d'au moins une source de lipoxygénase et d'hydroperoxyde-lyase, avec une source d'acides gras insaturés, la réaction s'effectuant sous agitation, en présence d'oxygène, dans un milieu à plusieurs phases comprenant au moins une phase solide et une phase huileuse caractérisé en ce que ledit milieu comporte, pour 100 parts de phase solide, 3 à 150 parts environ d'une phase huileuse, et éventuellement 0 à 250 parts environ d'une phase aqueuse.
