Vitamin deficiency arises when the dietary intake of essential vitamins is too low. Insufficient levels of vitamin weaken the body and induce diseases. Although the dietary intake of essential vitamins has increased through food fortification, there are still major issues of vitamin deficiency. Moreover, consumption of vitamins in classical food supplements presents drawbacks such as poor bioavailability and low stability, notably in the gastrointestinal tract conditions. To overcome such issues, vitamin nanoemulsions have been recently developed. Here, we review the design of vitamin nanoemulsions with various oils to meet specific needs; actual research and markets for vitamin nanoemulsions; and techniques for nanoemulsion characterization. © 2019, Springer Nature Switzerland AG.

Nanotechnology has seen exponential growth in last decade due to its unique physicochemical properties; however, the risk associated with this emerging technology has withdrawn ample attention in the past decade. Nanotoxicity is majorly contributed to the small size and large surface area of nanomaterials, which allow easy dispersion and invasion of anatomical barriers in human body. Unique physio-chemical properties of nanoparticles make the investigation of their toxic consequences intricate and challenging. This makes it important to have an in-depth knowledge of different mechanisms involved in nanomaterials's action and toxicity. Nano-toxicity has various effects on human health and diseases as they can easily enter into the humans via different routes, mainly respiratory, dermal, and gastrointestinal routes. This also limits the use of nanomaterials as therapeutic and diagnostic tools. This review focuses on the nanomaterial-cell interactions leading to toxicological responses. Different mechanisms involved in nanoparticle-mediated toxicity with the main focus on oxidative stress, genotoxic, and carcinogenic potential has also been discussed. Different methods and techniques used for the characterization of nanomaterials in food and other biological matrices have also been discussed in detail. Nano-toxicity on different organs-with the major focus on the cardiac and respiratory system-have been discussed. Conclusively, the risk management of nanotoxicity is also summarized. This review provides a better understanding of the current scenario of the nanotoxicology, disease progression due to nanomaterials, and their use in the food industry and medical therapeutics. Briefly, the required rules, regulations, and the need of policy makers has been discussed critically.

Nanomaterials in food and agriculture: An overview on their safety concerns and regulatory issues

Due to their small size and unique physico-chemical characteristics, nanomaterials have gained importance in the agri-food sector, notably in preservation and packaging. Future applications will focus on shelf life, food quality, safety, fortification and biosensors for contaminated or spoiled food, irrigating water and drinking water. Different types and shapes of nanomaterials are being used depending upon the needs and nature of the work in agriculture and water quality management. Here we review the application of nanotechnology in agriculture. The major points discussed are: (1) Nanomaterials for agriculture and water quality management. (2) Research interests such as nanoscale carriers, fabricated xylem vessels, nanolignocellulosic materials, clay nanotubes, photocatalysis, bioremediation of resistant pesticides, disinfectants, agricultural wastewater treatment, nanobarcode technology, quantum dots for staining bacteria and nanobiosensors. (3) Nanotechnological applications for agriculture, which includes nanolignodynamic metallic particles, photocatalysis, desalination, removal of heavy metals and wireless nanosensors. © 2017, Springer International Publishing AG.

Titanium dioxide nanoparticles are widely used in consumer products, paints and pharmaceutical preparations. They have been shown to induce cytotoxicity, genotoxicity and carcinogenicity—in vitro and in vivo. So far there is lack of standardized protocol for in silico analysis of nano-toxicological evaluations. In the present study, it was attempted to analyze the titanium dioxide nanoparticles-protein interaction through docking using AutoDock 4.0.5 software. Titanium dioxide nanoparticles with particle size of 1.09 nm were docked with different cellular proteins. Binding site area and volume has been determined by using CastP online server and docking has been performed at the active site as a pocket. The docked structures were analyzed for the most efficient binding with amino acids. It is the first study to report the interaction of titanium dioxide nanoparticles without any surface modification with proteins using docking analysis. The negative binding and docking energy inferred that the interaction of titanium dioxide nanoparticles with certain proteins is significant. Titanium dioxide nanoparticle shows significant interaction with intercellular adhesion molecule-1, P38 mitogen-activated protein kinases (P-38), placental growth factor and nuclear factor kappa-light-chain-enhancer of activated B cell proteins. Further, it has been observed that titanium dioxide nanoparticles show frequent interaction with proline, lysine as well as leusine. © 2015, The National Academy of Sciences, India.

A Novel Approach to Evaluate Titanium Dioxide Nanoparticle–Protein Interaction Through Docking: An Insight into Mechanism of Action

The use of nanoparticles in food or pharma requires a molecular-level perceptive of how NPs interact with protein corona once exposed to a physiological environment. In this study, the conformational changes of bovine serum albumin (BSA) were investigated in detail when exposed to different concentration of titanium dioxide nanoparticle by various techniques. To analyze the effects of NPs on proteins, the interaction between bovine serum albumin and titanium dioxide nanoparticles at different concentrations were investigated. The interaction, BSA conformations, kinetics, and adsorption were analyzed by dynamic light scattering, Fourier transform infrared spectroscopy and fluorescence quenching. Dynamic light scattering analysis confirms the interaction with major changes in the size of the protein. Fluorescence quenching analysis confirms the side-on or end-on interaction of 1.1 molecules of serum albumin to titanium dioxide nanoparticles. Further, pseudo-second order kinetics was determined with equilibrium contact time of 20 min. The spectroscopic analysis suggests that there is a conformational change both at secondary and tertiary structure levels. A distortion in both α-helix and β-sheets was observed by Fourier transform infrared (FTIR) spectroscopy. Fluorescence quenching analysis confirms the interaction of a molecule of bovine serum albumin to the single TiO2 nanoparticle. Further, pseudo-second order kinetics was determined with equilibrium contact time of 20 min. The data of the present study determines the detailed evaluation of BSA adsorption on TiO2 nanoparticle along with mechanism and adsorption kinetics. © 2016 Elsevier B.V.

Marigold (Tagets erecta L.), being an ornamental plant, posses medicinal properties like antimicrobial, insecticidal, wound healing and blood coagulation properties. Our recent works mainly focus on blood clotting activity of marigold leaf extracts. Blood clotting activity of leaf extract was examined using prothrombin time (PT) test by Owren method. The optimization of marigold leaf coagulating activity at different concentration of leaf extract and blood was done with Response surface method (RSM). Experiments showed that there was decrease in coagulation time with increase in extract concentration. Marigold leaves extract has shown very good blood coagulation property in lesser quantity i.e., in the range of μl. Also, phenolic compounds (like gallic acid, scopoletin, ferulic acid, quercecetin) were identified and quantified, which shows that because of presence of them, marigold leaf extract shows coagulation property. Antifungal, antibacterial and antioxidant activity are also analyzed. From the above findings, it can be concluded that along with antibacterial, antifungal and antioxidant properties, marigold leave extracts are also having very good coagulation property; so, in further research it can be developed as an antiseptic with coagulation property and can be developed as a potent product in the field of medicine and ointment.

The present study was carried out to fabricate the food grade Vitamin E acetate nanoemulsion using edible mustard oil and to evaluate its improved bioactivities. A food-grade Vitamin E acetate nanoemulsion was fabricated using the edible mustard oil and surfactant Tween-80. Flocculation was not observed for 15 days. The nanoemulsion was characterized for droplet morphology and size distribution using atomic force microscope and zetasizer, respectively. We observe a stable nanoemulsion of spherical morphology and a size distribution of 86.45 ± 3.61 nm. Further, the high-performance liquid chromatography method was used to determine the Vitamin E acetate concentration and encapsulation efficiency for the stable nanoemulsion. These nanoemulsions showed improved bioactivity, antioxidant, and antimicrobial activity and could be potentially used to increase the shelf life of fruit juice.
