Abstract
The present invention relates to a method for optimising the downstream processing of a protein-rich microalgae biomass of the Chlorella genus previously prepared by fermentation in heterotrophic conditions and in the absence of light, comprising: 1) providing biomass comprising more than 50% protein by dry weight of biomass; next, at low temperature, carrying out the following steps: 2) harvesting the biomass at the end of fermentation, 3) washing and concentrating the biomass, 4) optionally, lysing the biomass, next, without low temperature stress, 5) optionally, concentrating the biomass slurry, 6) applying heat treatment, 7) drying the biomass obtained in this way in order to obtain the product, a step of adjusting the pH to 7 being applied before or after the heat treatment step 6).
