The present invention relates to a method for preparing a microbial
cell product, said method comprising: providing an
aqueous suspension comprising microbial cells; subjecting said suspension to mechanical
cell disintegration at a temperature in the range of 15-35° C., preferably at a pH value in the range of 9-11, to obtain an
aqueous suspension comprising disintegrated microbial cells; separating the suspension to provide an extract enriched in
small cell fragments, and an extract enriched in
large cell fragments; and combining at least a portion of each extract, to provide said microbial
cell product. The invention further relates to a microbial cell product obtained or obtainable with said method. The invention further relates to the use of said product in foodstuffs, for example as a substitute for egg-white; in animal foodstuffs; and / or in cosmetic formulations.
