Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX

products and domestic cooking to enhance the appearance of food. To obtain specific hues, inorganic food additives containing (nano)particles are mixed in varying concentrations, and pearlescent pigments ...

Advances in the physicochemical characterization of nanoparticles in a regulatory context.

specifying, registering and labelling, as well as characterizing particulate (nano)materials for risk assessment, require measurement of the physicochemical properties of their constituent particles. Because of ...

Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products

for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP- MS) is thereby a promising technique as it is capable of sizing and ...

Physicochemical characterisation of several types of the E171 food additive

optimized conditions, representative TEM micrographs could be recorded and the ParticleSizer image analysis software succeeded in applying noise reduction and background subtraction, allowing robust automatic ...

Characterization of the nano-sized fraction of silver particles in food additive E174 by EM and sp-ICP-MS

Publication Type: Scientific poster, presentation or proceeding Authors: Sandra De Vos; Eveline Verleysen; M. Ledecq; Nadia Waegeneers; Jan Mast Source: IMEKOFOODS 4 (2019) Service:  Éléments traces et nanomatériaux Spoorelementen en nanomaterialen Trace ...

Physicochemical Characterisation of the E171 Food Additive

X-ray spectroscopy (EDX), were reliably detected and measured using the ParticleSizer software. In the most dispersed state, the particle size measurements by TEM and sp- ICP- MS agreed well. The ...
