Pulsed electric field pre-treatment can be used for loading sugars into living cells, which may make cells more robust during subsequent spray drying. In this study we investigated the effect of the (change of) drying medium after PEF pre-treatment with trehalose for its impact on survival during subsequent spray drying for L. plantarum WCFS1. Our results showed that when trehalose was used as drying medium, no difference in survival with and without PEF pre-treatment was observed. However, when reconstituted skim milk and maltodextrin DE19 were used as drying medium an increased survival of the PEF-treated culture was observed compared to the control.
