Biotechnology Letters.

After being dried, L. kefir 8321 and L. kefir 8348 had a decrease in viability of 0.29 and 0.70 log cfu/ml respectively, while the addition of different protectants improved the survival of both strains significantly. During storage, bacterial survival was significantly higher under lower conditions of RH (0–11%), and monosodium glutamate and FOS proved to be the best protectants.engLactobacillus kefirSpray dryingProtectantsSurvivaljournal article10.1007/s10529-010-0491-6
