Safety assessment of titanium dioxide (E171) as a food additive.

Panel to be reliable, including data obtained with TiO nanoparticles (NP s) and data from an extended one-generation reproductive toxicity (EOGRT) study. Less than 50% of constituent particles by number in ...

Physicochemical characterization of nanoparticles in food additives in the context of risk identification

Publication Type: Peer reviewed scientific article Authors: Verleysen, Eveline; Waegeneers, Nadia; De Vos, Sandra; Brassinne, Frédéric; Ledecq, Marina; Van Steen, Frederic; Andjelkovic, Mirjana; Janssens, Raphael; Mathioudaki, Stella; Delfosse, Lotte; Mac ...

Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.

is a specific concern for the E174 risk assessment. This study characterised the fraction of silver (nano)particles in 10 commercially available pristine E174 food additives and 10 E174-containing ...

Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery

E174 is a specific concern for the E174 risk assessment. This study characterised the fraction of silver (nano)particles in 10 commercially available pristine E174 food additives and 10 E174-containing ...

Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo

the influence of nanoparticle (NP) agglomeration and aggregation on toxicity is poorly understood although it is strongly believed that smaller the size of the NP s greater the toxicity. ...

Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.

Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory context. ...

A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.

and to compare these with standard approaches, i.e. dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), microscopy (TEM), membrane filtration, centrifugation and dialysis. Seven ...

Short-term biodistribution and clearance of intravenously administered silica nanoparticles

concerns have been raised about potential adverse effects of synthetic amorphous silica, commonly used as food additive (E551), since silica nanoparticles have been detected in food containing E551. We ...
