Baranowska-Wójcik E, Welc-Stanowska R, Wiącek D, Nawrocka A, Szwajgier D. The interactions of pectin with TiO 2 nanoparticles measured by FT-IR are confirmed in a model of the gastrointestinal tract. Food Res Int 2024; 189:114509.

Abstract
The presence of nanoparticle fractions (<100 nm, NPs) in the food additive TiO2 (E171) rises concerns about its potential harmful impact on human health. The knowledge about the interaction of TiO2 NPs with food components is limited to proteins or polyphenols. The present paper is the first to report on interactions between TiO2 NPs and high molecular pectins that form gels in boluses and are remain nearly intact during digestion until they reach the colon. Direct interactions were studied using Fourier Transform Infrared Spectroscopy while indirect ones were monitored by measuring the "absorption" of TiO2 using a 0.2 microfiltration membrane, during in vitro digestion in a model of the gastro-intestinal tract. The FT-IR spectra registered for pectin-TiO2 NPs solutions confirmed changes in band intensities at 1020, 1100, 1610, and 1740 cm-1, suggesting interactions taking place mainly via the COO- groups. Furthermore, the I(1020)/I(1100) ratio was decreased (C-O stretching vibrations), suggesting partial blocking of the skeletal vibrations caused by interactions between pectin and TiO2. The modelled in vitro digestions confirmed that the "availability" of Ti was reduced when TiO2 NPs were combined with pectin, as compared to TiO2 NPs "digested" alone.

Abstract
The biomedical use of nanoparticles (NPs) has been the focus of intense research for over a decade. As most NPs are explored as carriers to alter the biodistribution, pharmacokinetics and bioavailability of associated drugs, the delivery of these NPs to the tissues of interest remains an important topic. To date, the majority of NP delivery studies have used tumor models as their tool of interest, and the limitations concerning tumor targeting of systemically administered NPs have been well studied. In recent years, the focus has also shifted to other organs, each presenting their own unique delivery challenges to overcome. In this review, we discuss the recent advances in leveraging NPs to overcome four major biological barriers including the lung mucus, the gastrointestinal mucus, the placental barrier, and the blood-brain barrier. We define the specific properties of these biological barriers, discuss the challenges related to NP transport across them, and provide an overview of recent advances in the field. We discuss the strengths and shortcomings of different strategies to facilitate NP transport across the barriers and highlight some key findings that can stimulate further advances in this field.

Dysregulation along the gut microbiota-immune system axis after oral exposure to titanium dioxide nanoparticles: A possible environmental factor promoting obesity-related metabolic disorders. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 330:121795.

Abstract
Food additives are one major hallmark of ultra-processed food in the Western-diet, a food habit often associated with metabolic disorders. Among these additives, the whitener and opacifying agent titanium dioxide (TiO2) raises public health issues due to the ability of TiO2 nanoparticles (NPs) to cross biological barriers and accumulate in different systemic organs like spleen, liver and pancreas. However before their systemic passage, the biocidal properties of TiO2 NPs may alter the composition and activity of the gut microbiota, which play a crucial role for the development and maintenance of immune functions. Once absorbed, TiO2 NPs may further interact with immune intestinal cells involved in gut microbiota regulation. Since obesity-related metabolic diseases such as diabetes are associated with alterations in the microbiota-immune system axis, this raises questions about the possible involvement of long-term exposure to food-grade TiO2 in the development or worsening of these diseases. The current purpose is to review the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 NPs may increase the susceptibility to develop obesity-related metabolic disorders.

Abstract
E171 (TiO2- Ttitanium dioxide), a food colourant containing nano fractions, is one of the additives used e.g. in the food industry, whose consumption may have a negative impact on human health. In order to determine the ability of food products and intestinal lactic acid bacteria to interact with TiO2, we conducted in vitro "digestions" of a food matrix (meat/vegetable puree soup) using an advanced in vitro model of the "gastrointestinal tract". The "bioaccessibility" of TiO2 was simulated using microfiltration (0.2 µm) of the post-digestive fluid. We observed changes in the content of TiO2 in the microfiltrates obtained at various stages of the in vitro digestions, dependent on the stage of the process. This result suggests that TiO2 interacts with food components and bacterial cells. Furthermore, scanning electron microscopy revealed visible morphological changes to bacterial cells in the presence of TiO2.

Abstract
The food colorant E171 (TiO2) containing nano fractions can cause potential health problems. In the presented work, we used a “gastrointestinal tract” model (oral→large intestine) to “digest” a fruit smoothie in the presence of TiO2 nanoparticles and the Lactiplantibacillus plantarum B strain. The TiO2 migration was measured using the microfiltration membrane (0.2 µm; model of “TiO2 bioacessability”). We observed that the addition of the smoothie reduced the Ti content in the microfiltrate (reduced “bioacessability”) at the “mouth”, “stomach” and “large intestine” stages, probably due to the entrapment of Ti by the smoothie components. A significant decrease in Ti “bioaccessibility” at the “gastric” stage may have resulted from the agglomeration of nanoparticles at a low pH. Additionally, the presence of bacterial cells reduced the “bioaccessibility” at the “large intestine” stage. Microscopic imaging (SEM) revealed clear morphological changes to the bacterial cells in the presence of TiO2 (altered topography, shrunk-deformed cells with collapsed walls due to leakage of the content, indentations). Additionally, TiO2 significantly reduced the growth of the tested bacteria. It can be stated that the interactions (most probably entrapment) of TiO2 in the food matrix can occur during the digestion. This can influence the physicochemical properties, bioavailability and in vivo effect of TiO2. Research aimed at understanding the interactions between TiO2 and food components is in progress.

Abstract
During the 21st century, the incidence and prevalence of inflammatory bowel disease (IBD) is rising globally. Despite the pathogenesis of IBD remaining largely unclear, the interactions between environmental exposure, host genetics and immune response contribute to the occurrence and development of this disease. Growing evidence implicates that food additives might be closely related to IBD, but the involved molecular mechanisms are still poorly understood. Food additives may be categorized as distinct types in accordance with their function and property, including artificial sweeteners, preservatives, food colorant, emulsifiers, stabilizers, thickeners and so on. Various kinds of food additives play a role in modifying the interaction between gut microbiota and intestinal inflammation. Therefore, this review comprehensively synthesizes the current evidence on the interplay between different food additives and gut microbiome alterations, and further elucidates the potential mechanisms of food additives–associated microbiota changes involved in IBD.

Abstract
Nanotechnology utilises particles of between 1 and 100 nm in size. In recent years, it has enjoyed widespread application in a variety of areas. However, this has also raised increasing concerns regarding the effects that the use of nanoparticles may have on human health. The nanoparticles of titanium dioxide (TiO2 NPs) are among the most promising nanomaterials and have already found wide use in cosmetics, medicine and, the food industry. A nano-sized (diameter < 100 nm) fraction of TiO2 is present, at a certain percentage, in the E171 ( in the EU) pigment commonly used as an additive in food, whose presence raises particular concerns in terms of its potential negative health impact. The consumption of E171 food additive is increasingly associated with disorders of the intestinal barrier, including intestinal dysbiosis. It may disrupt the normal functions of the gastrointestinal tract (GIT) including: enzymatic digestion of primary nutrients (lipids, proteins, or carbohydrates). The aim of this review is to provide a comprehensive and reliable overview of studies conducted in recent years in terms of the substance's potentially negative impact on human and animal alimentary systems.

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, questions concerning its effect on the gastrointestinal microbiota have been raised. In the present study, we examined interactions between bacteria and TiO2. The study involved six pathogenic/opportunistic bacterial strains and four different-sized TiO2 types: three types of food-grade E171 compounds and TiO2 NPs (21 nm). Each bacterial strain was exposed to four concentrations of TiO2 (60, 150, 300, and 600 mg/L TiO2). The differences in the growth of the analyzed strains, caused by the type and concentration of TiO2, were observed. The growth of a majority of the strains was shown to be inhibited after exposure to 300 and 600 mg/L of the food-grade E171 and TiO2 NPs.

Abstract
AbstractOne of the dangerous pathogens that display high resistance to antibiotics is Salmonella enterica (S. enterica), which infects humans and animals. In this study, a new approach was proposed to fight antibiotic-resistant bacteria by using silver nanoparticles (AgNPs) with adding the phage ZCSE6. The biosynthesized AgNPs were characterized by analysis of spectroscopy profile of the UV–Vis, visualize the morphology, and size with transmission electron microscopy. Both minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were assessed. In addition, the AgNPs were able to control the biofilm formation of S. enterica, also, heavy metals detection by AgNPs and their application in milk. UV–Vis spectra showed a surface resonance peak of 400 and 430 nm corresponding to the formation of AgNPs capping with Ocimum basilicum L. and Hibiscus sabdariffa L., respectively. The MIC and MBC values were 6.25 µg/ml to inhibit the growth of S. enterica and 12.5 µg/ml from killing the bacteria and it was decreased to 1.5 µg/ml when combined with the phage. In the present study, AgNPs were combined with phage ZCSE6 to obtain a synergetic antimicrobial activity. Moreover, it increases the milk’s shelf-life and senses the Cd2+ at a concentration of 1 mM in the water.
