Abstract The contribution to cheese proteolysis and sensory profile of four potentially probiotic non-starter lactobacilli strains was assessed in two different models: soft and semi-hard cheeses. All the strains were able to grow in both types of cheese, where they maintained high levels during ripening. Overall, adjunct cultures of Lactobacillus rhamnosus showed the strongest influence in peptidolysis, which was verified by changes in peptide profiles and increase of free amino acids concentration. Nevertheless, some cheeses treated with L. rhamnosus also showed post-acidification during ripening and decreased sensory characteristics compared to controls. Cheeses with adjunct cultures of Lactobacillus casei I90 and Lactobacillus plantarum...
