Process comprising reducing a fermentation broth comprising 2'-fucosyllactose to produce a treated fermentation broth comprising 2'-fucosyllactose and 2'-fucosyllactitol; isolating a stream comprising 2'-fucosyllactose and 2'-fucosyllactitol from the treated fermentation broth; purifying the isolated stream; concentrating the purified isolated stream; dewatering the concentrated purified isolated stream, thereby forming a prebiotic solids product comprising 2'-fucosyllactose and 0.2 to 6.0 wt.% of 2'-fucosyllactitol based on the total wt.% of the prebiotic solids product, wherein the concentrating step and dewatering step can be performed in any order.
