Title : Characterization of engineered titanium dioxide nanoparticles (TiO2 -NP) in selected food products
Abstract:
TiO2 an E171 manufacturer-made food additives, is extensively utilized as a colorant in drug and a food products. Some studies showed that most of confectionary and food items contain inexplicable particles. The aim of this article is the determine the size and structure of TiO2 Nanoparticles in different food products. Ten food samples including coffee cream, white chocolate concentrate, frosting, gum, yogurt candy, hard candies and chewy candies were investigated for this purpose. The crystalline structure and particle size of TiO2 were determined by using Powder X-ray Diffraction (PXRD) and Transmission Electron Microscopy (TEM). TEM images elaborated that a few of the extracted nanoparticles had rod-like shape, but most were spherical. Also, the particle sizes of TiO2 have wide size distribution between 12-450nm. Thus, to avoid human health risk crucial factors such as size, and shape should be considered and regulated by food safety authorities.
