DESCRIZIONE
The invention relates to a method for preparing a flour of lipid-rich microalgae, which comprises the following steps: (a) providing a biomass of microalgae comprising more than 50% lipids per dry weight of biomass; (b) lysing the microalgae; (c) concentrating the microalgae lysate to a solids content of more than 25 wt %, preferably to a solids content of 35 wt % to 50 wt %; (d) applying a thermal treatment to the lysate thus concentrated; (e) homogenising the lysate obtained in step (d) under high pressure, so as to obtain a stable emulsion; and (f) drying said emulsion in order to obtain the microalgae flour.
