Bio-Labneh was produced from cow’s milk using Jerusalem artichoke tubers powder (JATP) inoculated by Lactobacillus acidophilus LA-5. The effect of different concentrations (1, 3 and 5%) of JATP on the chemical composition, organoleptic properties and the growth, and activity of Lactobacillus acidophilus LA-5 were investigated. Significant differences were observed in the chemical composition and counts of viable bacteria between treatments either in fresh or stored Labneh. Acidity % in all treatments was significantly increased and pH was decreased with increasing storage period. The viable count of Lactobacillus acidophilus was also increased through the first 7 days then decreased gradually during the storage period. Generally, using JATP in manufacturing bio-Labneh had acceptable with 1% JATP, while 3% JATP received the highest total scores and the growth of Lactobacillus acidophilus LA-5.
