Carrier food matrix had a significant influence on the in vitro gastrointestinal tolerance of all three probiotics when exposed to both highly acidic conditions (pH 2.0) and 0.3% bile. Exposure to conditions of lower pH (pH 2.0) resulted in a significant reduction in probiotic viability during simulated gastric transit tolerance compared to pH levels of 3.0 and 4.0. However, ice cream was generally found to improve the acid and bile tolerance of the probiotics compared to plain and stirred fruit yogurts. In a similar manner, the in vitro adhesion ability of probiotics was found to be influenced by the carrier food matrix, with fruit yogurt providing the most favorable outcomes, although in all cases a substantial number of viable bacteria (10⁵–10⁶ cfu/g) were able to attach to the Caco-2 cells.]]> Sat 24 Mar 2018 07:59:21 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22562 Sat 24 Mar 2018 07:14:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53596 Fri 08 Dec 2023 16:00:13 AEDT ]]>
