In the present work, the compared effect of 1 percent inulin and fat replacers (1 percent Dairy-Lo and 0.1 percent Dariloid) on chemical properties, growth and stability of probiotic bacteria and sensory attributes in Labneh cheese during storage (30 days) at 5 deg C was studied. Three strains of probiotic bacteria were used, Lactobacillus reuteri B-14171, Lactobacillus johnsonii B-2178 and L. salivarius B-1950, with a yoghurt starter cultures. Addition of inulin, Dairy-Lo and Dariloid increased the soluble nitrogen, total volatile fatty acids, acetaldehyde and diacetyl. The effect of added prebiotics on soluble tyrosine and tryptophan was more pronounced. All strains showed good growth and survival in the presence of prebiotics. Initial counts of probiotic bacteria and their subsequent survival were better in the products supplemented with inulin. The most acceptable cheeses were those supplemented with 1 percent inulin
