Corrigendum: Impact of the food additive titanium dioxide (e171) on gut microbiota-host interaction (Front. Nutr., (2019), 6, 10.3389/fnut.2019.00057)

In the original article, there was an error. In the Materials and Methods section, there was an error concerning the supplier of E171. A correction has been made to the Materials and Methods section, subsection E171 Characterization, Size and Morphology: “Food grade TiO₂ was purchased from All Color Supplies PTY. Average hydrodynamic diameter, polydispersity index and zeta potential of the TiO₂ nanoparticles dispersed in drinking water were determined with a Malvern Zetasizer Nano ZS at 25^◦ C. The dispersion was measured 3 times for both size and zeta potential. The size distribution and shape of the TiO₂ nanoparticles dispersed in mice drinking water were determined using a NanoSight NS300 (equipped with a sCMOS camera) at 25^◦ C. The dispersion was measured 5 times (1 min per measurement). The size distribution and shape of the TiO₂ nanoparticles dispersed in drinking water were further investigated using a Zeiss Ultra Plus scanning electron microscope operated at an accelerating voltage of 10 kV. A drop of the nanoparticle dispersion was allowed to dry on a stub, after which ∼20 Å of platinum metal was sputter coated onto the stub under vacuum to prevent charging.” The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
