Abstract
The invention relates to a method for preparing a protein isolate of the biomass of microalgae of the genus Chlorella, characterised in that it comprises the following steps: supplying a microalgal biomass produced by fermentation, washing the biomass so as to eliminate the soluble interstitial compounds and concentrating the biomass, mechanically grinding the washed and concentrated biomass in a horizontal ball grinder-type system in order to produce an emulsion, destructuring the emulsion thus produced, triple-phase separation so as to separate the soluble fraction from the fractions containing the lipids and the cell debris, recovery of the soluble fraction thus produced in order to produce the soluble protein isolate, then evaporation, pasteurisation and atomisation of said protein isolate.
