Abstract

The invention relates to a method for producing a dehydrated sourdough where a microbiol biomass is homogeneously mixed with a dehydration medium comprised of flour and water in order to produce a wet sourdough, characterised in that the wet sourdough is dehydrated at a temperature lower than 40 DEG C between two successive steps, first at any dehydration speed while the water activity aw is higher than or equal to 0.990 and then, as soon as the water activity aw drops to a value lower than 0.990, the sourdough is dehydrated at a lower hydrous potential gradient corresponding to dehydration rates comprised between -0.5kPa/s and -5.0kPa/s until the water activity aw drops to a value substantially equal to 0.15.
