doi:10.3969/j.issn.1674-8115.2022.02.014

Abstract

Abstract:

With the improvement of quality of life and changes of dietary habits, people's requirements for food should not only include food and clothing, but also color, aroma, taste, shape and meaning, in which food additives play a very important role. Titanium dioxide (TiO₂) is often widely used as a pigment additive in food and daily necessities, so people will inevitably contact and ingest TiO₂ nanomaterials in daily life. Based on this, the article reviews the effect of TiO₂ nanomaterials on digestive tract tissues and gastrointestinal microbiome, as well as its direct and indirect pro-inflammatory effects in the occurrence and development of gastrointestinal inflammation, further providing reference improving the safety of TiO₂ nanomaterials in the food field.

Key words: nanomaterial, titanium dioxide (TiO₂), digestive tract, gastrointestinal microbiome, inflammatory response
