The present invention relates to a method for separating biomass from a solution comprising bi-omass and at least one aroma compound. comprising providing the solution comprising bio-mass and aroma compounds. lowering the pH value of the solution below 7 by adding at least one acid to the solution comprising biomass and the at least one aroma compound. adding an adsorbing agent to the solution comprising biomass and aroma compounds. and carrying out first membrane filtration so as to separate the biomass from the solution comprising the at least one aroma compound. La présente invention concerne un procédé de séparation de biomasse d'une solution comprenant de la biomasse et au moins un composé aromatique consistant à utiliser la solution comprenant de la biomasse et des composés aromatiques, à abaisser la valeur de pH de la solution en-deçà de 7 en ajoutant au moins un acide à la solution comprenant de la biomasse et le ou les composé(s) aromatique(s), à ajouter un agent adsorbant à la solution comprenant de la biomasse et des composés aromatiques, et à mettre en œuvre une première filtration par membrane de manière à séparer la biomasse de la solution comprenant le ou les composé(s) aromatique(s).
