Abstract
The present invention relates to a process for optimizing the storage stability of a freeze dried bacteria-containing product obtained from a bacteria-containing concentrate, wherein the process is carried out at a pressure which will provide a sublimation temperature which is at least 10° C. above the melting point of the frozen bacteria-containing concentrate. Further, the present invention relates to the freeze dried concentrates per se.
