In this study, the influence of phytase-producing Bifidobacterium strains during the bread-making process (direct or indirect) on final bread Fe dialyzability and ferritin formation in Caco-2 cell as a measure of cell Fe uptake were assessed. The addition of bifidobacteria significantly reduced the InsP6 + InsP5 concentrations comparing to control samples. Fe dialyzable contents for samples with bifidobacteria were increased 2.3-5.6-fold and dialyzability was improved by 2.6-8.6% compared to controls. However, this was not reflected in an increase of Fe uptake by Caco-2 cells as was predicted by the phytate/Fe molar ratios. The results demonstrated the usefulness of phytase-producing bifidobacteria to reduce phytate during bread-making process and to increase Fe accessibility, although, the effects appeared to be still insufficient to improve Fe bioavailability in Caco-2 cells. Further refinement of the use of phytase-producing bifidobacterial strains and/or bread-making technological processes is deserved for improving Fe uptake.
