The present invention relates to a method for fractionating fractions of biomass of protein-rich microalgae of the genus Chlorella, characterized in that the method comprises the steps of: providing microalgal biomass produced by fermentation; either Optionally, the biomass is washed to remove interstitial soluble compounds; the biomass is thermally permeabilized at a temperature from 0°C to 150°C, preferably from 100°C to 150°C, for a period of several seconds to 5 minutes, preferably for 5 minutes seconds to 1 minute; separation of the thus permeabilized biomass from the soluble fraction using centrifugation techniques, especially multistage centrifugation; optionally, recovery and clarification of the soluble fraction thus obtained by microfiltration for removal therefrom Insolubles remained; the aforementioned soluble fraction was separated by precipitation, so as to obtain peptide isolates and peptide concentrates. |
