Abstract:
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

Abstract:
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

Abstract:
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).

Abstract:
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

Abstract:
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

Abstract:
Food-grade titanium dioxide (TiO2) containing a nanoparticle fraction (TiO2 NPs -nanoparticles) is widely used as a food additive (E171 in the EU). In recent years, it has increasingly been raising controversies as to the presence or absence of its harmful effects on the gastrointestinal microbiota. The complexity and variability of microbiota species present in the human gastrointestinal tract impede the assessment of the impact of food additives on this ecosystem. As unicellular organisms, bacteria are a very convenient research model for investigation of the toxicity of nanoparticles. We ex

Abstract:
Nanoparticles (NPs) are substances that are used in many fields, especially in antimicrobial and food additives. Consumable nanoparticles, also known as food nanoparticles, are separated into organic and inorganic nanoparticles. Organic NPs can be classified as proteins, carbonates, phospholipids, and lipids, while inorganic NPs can be classified as silica (SiO2, E571), zinc oxide (ZnO), titanium dioxide (TiO2, E171), iron oxide (Fe2O3, E172), copper (Cu), gold (Au, E175) and silver (Ag, E174). Organic nanoparticles are not long lasting in the body. However, is it possible to make the same claim about inorganic nanoparticles? Inorganic nanoparticles are employed as food additives, vitamin supplements, and food packaging in the nutrition of both humans and animals. Food nanoparticles that make products brighter, tastier, more shelf-stable, and more antimicrobially resistant influence the liver, renal, digestive, respiratory, and genital systems once they enter the body. NPs can enter the male genital tract, adversely affect the testicles and sperm, and even affect the hypothalamo-pituitary axis, causing hormonal disorders. The effects of inorganic NPs on testes and spermatozoa vary depending on the diameter and composition of this NPS. Studies with some inorganic NPs show that low doses have positive effects on the antioxidant system and harmful effects occur when their concentrations are increased, while some have toxic effects even at very low concentrations. Given all of this information, might consumable nanoparticles be one of the causes of rising male infertility? The aim of this review is to explain how nanoparticles affect the male genital system and sperm quality and to provide insights into whether they might be one of the factors contributing to male infertility.
