The present invention relates to a method for providing a SCP product from a biomass material wherein said SCP product comprising a reduced amount of nucleic acids relative to the naturally occurring amount of nucleic acids in the biomass material, the method comprising the steps of: (i) providing the biomass material； (ii) subjecting the biomass material to a process of cell disruption, providing a disrupted biomass material； (iii) applying the disrupted biomass material to a first separation process resulting in a first retentate comprising proteins and/or cell debris, and a first permeate comprising nucleic acids； (iv) subjecting the first permeate to a second treatment separating the nucleic acids from vitamins, minerals and/or amino acids； (v) optionally, combining the first retentate obtained in step (iii) with the vitamins, minerals and/or amino acids obtained in step (iv), providing the SCP product comprising a reduced amount of nucleic acids relative to the naturally occurring amount of nucleic acids.
