| abstract |
The present invention relates to a method for producing a biopolymer, wherein the biopolymer has a defined (average) average molecular weight, the method comprising: Lyophilizing a composition comprising a biopolymer having a native high molecular weight, optionally purifying and / or isolating the biopolymer; Here, the temperature during the sublimation process is selected to promote controlled and defined degradation of the biopolymer. |
