Abstract
This study investigates the influence of tomato and feijoa juices as fermentable carriers of Lactobacillus plantarum (LP DSM20205) on the ability of the bacterium to improve intestinal barrier function using the trans-epithelial electrical resistance (TEER) assay in an apical anaerobic model. The survival of LP DSM20205 in different fruit juices during in vitro digestion, its adhesion capacity, and potential cytotoxic effect on Caco-2 cells were also studied. The results showed that carrier fruit juices have a significant influence on LP DSM20205 growth, survival during in vitro digestion, adhesion capacity, and TEER. All fermented samples were not cytotoxic to Caco-2 cells. The fermented tomato juice showed the largest improvement to intestinal barrier integrity. The digested fermented juices did not increase TEER, although the LP DSM20205 in these samples adhered well. Therefore, LP DSM20205 has the potential to be used as a probiotic in the production of fermented tomato and feijoa juices.
