摘要/Abstract

摘要：

随着生活质量的提高和饮食习惯的改变，人们对食品的要求除了能够满足温饱外，还兼具色、香、味、形、意等方面，其中食品添加剂扮演了十分重要的角色。由于在食品和日用品中，二氧化钛（titanium dioxide，TiO₂）常被作为色素添加剂而大量使用，使得人们会不可避免地接触和摄入TiO₂纳米材料。基于此，该文就TiO₂纳米材料被机体摄入后对消化道内细胞组织及微生物群的影响及该颗粒在肠道炎症的发生和发展中发挥的直接和间接的促炎作用进行综述，从而为进一步提升TiO₂纳米材料在食品领域中应用的安全性提供参考。

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
