The invention relates to a method for stabilising a biomass of microalgae containing oxidation-sensitive metabolites selected from the group consisting of carotenoids (lutein, etc.), monounsaturated and polyunsaturated fatty acids (palmitoleic acid, oleic acid, linoleic acid, etc.), chlorophyll pigments (chlorophyll A and B, etc.) and vitamins (vitamin B9 and B12, etc.) taken individually or together, more specifically carotenoids, said method comprising the fermentation of said biomass in heterotrophic conditions. La presente invención se refiere a un método para estabilizar una biomasa de microalgas que contiene metabolitos sensibles a la oxidación seleccionados del grupo que consiste en carotenoides (luteína, etc), ácidos grasos monoinsaturados y poliinsaturados (ácido palmitoleico, ácido oleico, o ácido linoleico, etc.), pigmentos de clorofila (clorofila A y B, etc.) y vitaminas (vitaminas B9 y B12, etc.) tomadas por sí solas o en combinación, más particularmente carotenoides, donde dicho método comprende la fermentación de dicha biomasa en condiciones heterotróficas.
