Streszczenie:

E171 (titanium dioxide) is a food additive that has been authorized for use as a food colorant in the European Union. The application of E171 in food has become an issue of debate, since there are indications that it may alter the intestinal barrier. This work applied standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass spectrometry (spICP-MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the c

Streszczenie:

Titanium dioxide (TiO2) is one of the most extensively utilized food additives (E171) in the food industry. Along with nanotechnology development, the concern about the presence of nanostructured particles in E171 TiO2 and commercial food products is growing. In the present study, the physicochemical properties of commercially available E171 TiO2 particles, including particle size distribution, were investigated, followed by their cytotoxicity and intestinal transport evaluation. The fate determination and quantification of E171 TiO2 in commercial foods were carried out based on the analytical

This study investigated the DNA damage and apoptosis in colon cancer cells HCT-116 and Caco-2 induced by engineered titanium dioxide nanoparticles (TiO2-NPs) (60 nm) and titanium dioxide food additive E171. MTT assays showed that both chemical forms significantly reduced cancer cell viability in a dose-dependent manner. In particular the food additive E171 induced a pronounced inhibitory effect on the growth of HCT-116 and Caco-2 cell lines (E171 IC50: 3.45 mg/L for HTC-116 and 1.88 mg/L Caco-2; TiO2-NPs 60 nm IC50: 41.1 mg/L for HTC-116 and 14.3 mg/L for Caco-2).

Streszczenie:

Titanium dioxide (TiO2) is present in many different food products as the food additive E171, which is currently scrutinized due to its potential adverse effects, including the stimulation of tumor formation in the gastrointestinal tract. We developed a transgenic mouse model to examine the effects of E171 on colorectal cancer (CRC), using the Cre-LoxP system to create an Apc-gene-knockout model which spontaneously develops colorectal tumors. A pilot study showed that E171 exposed mice developed colorectal adenocarcinomas, which were accompanied by enhanced hyperplasia in epithelial cells, lym

Introduction. Titanium dioxide in the Russian Federation is approved for use in the food industry, in the production of medicines and hygiene products. The food additive E171 is a mixture of micro- and nanoparticles of TiO2. In 2010, IARC classified TiO2 in nanoform as a probably carcinogenic to humans (Group 2B). In vitro and in vivo studies of the genotoxicity of titanium dioxide revealed contradictory results, indicating both the presence and absence of TiO2 mutagenicity.  The aim of the work is to evaluate the mutagenicity of the food additive E171 in the Ames test using standard and

Streszczenie:

Measurement of primary particle size distributions is fundamental to determining if a material should be classified as a nanomaterial according to the European Commission recommended definition. This is of particular relevance to alimentary products, where current regulation requires that any additives containing nanoforms be explicitly declared as such in the ingredients’ list. Currently, Electron Microscopy is the only instrumental technique able to reliably classify materials as nanomaterials. To verify the nanostatus of a material using this technique, it is essential to firstly extract th

Le projet de thèse NanoTi-Food vise principalement à améliorer la fiabilité de la caractérisation des nanoparticules de TiO2 (NPs) et à acquérir des connaissances sur l'additif alimentaire E171 y compris la migration de ces NP à partir des emballages alimentaires. Dans la première partie de l'étude (à réaliser à Anses), une nouvelle approche pour la caractérisation des NP de TiO2 sera développée et optimisée en utilisant l'approche « single particle » en combinaison avec la spectrométrie de masse à plasma à couplage inductif triple quadripôle (Sp-ICP- QQQMS).
