Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.

spectrometry (spICP- MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the critical factors that determine the measurement of the particle size distribution by TEM. ...

Biological monitoring of exposure to pesticide residues among Belgian florists

during preparing bouquets and handling contaminated flowers. A study was conducted among volunteer Belgian florists in order to assess their total exposure by measuring concentrations of pesticides (parent ...

Impact of DNA extraction on whole genome sequencing analysis for characterization and relatedness of Shiga toxin-producing Escherichia coli isolates

study evaluated eight commercial DNA preparation kits for their potential influence on: (i) DNA quality for Nextera XT library preparation; (ii) MiSeq sequencing (data quality, read mapping against ...

Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case

amplification and sequencing of the 16S-rRNA gene, the potential presence of FE producing bacteria in FE preparations. First, the specificity was verified using all microbial species reported to produce FE. ...

Dietary exposure of the Belgian population to mineral oil

prepared coffee. This study gives an account of the dietary exposure of the Belgian population to mineral oil for the first time and reports the associated uncertainties. Service:  Évaluation des risques et de ...

Analysis of mineral oil in food: An analytical challenge

matrix has also an important impact, not only on data integration and interpretation but also on the sample preparation. Due to the presence of olefins and natural alkanes, some matrices require auxiliary ...

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

samples were prepared for analysis according to a slightly modified version of the method of Jensen et al. [2]. The E174 food additives showed a large silver background concentration combined with ...

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

However, no validations have yet been performed with food additives or real samples containing food additives requiring a sample preparation step prior to analysis. A single-particle inductively coupled ...
