Publication Type: Peer reviewed scientific article Authors: Marie, Deckers; Kevin, Vanneste; Raf, Winand; Marijke, Hendrickx; Pierre, Becker; C.J., De; Deforce, Dieter; Fraiture, Marie-Alice; H.C., Roosens, Source: Food Control, Volume 117 (2020) Keywords ...
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 ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
synthetic nano- and submicron FeOx with different mineralogy and coating were prepared and two soil solutions were included. The FlFFF was optimized for Fe recovery, yielding 70-90%. The FlFFF determines ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
combines standard operating procedures for specimen preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
bisphenols (BP) (BPA, BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- ...
Syllabus of the workshop physicochemical characterization of nano-sized particles in food
particles in food additives (including E171 and E174) and in food products by TEM Practical experience in sample/ TEM-specimen preparation and application of the ParticleSizer software for the analysis of TEM ...
