Abstract:
The aim of this study was to test the compatibility of two selected Lactobacillus strains with different prebiotic carbohydrates in order to develop a synbiotic cheese. Initially, the growth of the probiotic lactobacilli with the prebiotic formulations was monitored in optimized growth medium and in milk. Afterwards, semi-hard cheeses were manufactured with the selected combination of Lb. paracasei INIA P272 and fructo-oligosaccharides (FOS). Results showed that the addition of FOS did not affect Lb. paracasei viability in the cheese after 28 days of ripening, but a higher viability of this strain was achieved in the presence of FOS when cheese was tested in a colonic model. Thus, the inclusion of FOS in the cheese could have a beneficial effect by increasing the probiotic strain viability in the host.
