Development of a real-time PCR marker targeting a new unauthorized genetically modified microorganism producing protease identified by DNA walking
DNA walking analysis was performed on a protease product suspected to contain a new unauthorized genetically modified microorganism (GMM). Though the characterization of unnatural associations of ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
the particles’ number concentration and a number of cumulative particle size distribution parameters (D0, D10, D50, D99.5, D99.8 and D100). The evaluated method’s performance characteristics were, the ...

Production of Alternaria Toxins in Yellow Peach (Amygdalus persica) upon Artificial Inoculation with Alternaria alternate
28 °C to simulate the current storage conditions that consumers use, and the Alternaria toxins (AT s) contents from different parts of the fruits were analyzed via ultra-high-performance liquid ...
A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products
study, this approach was performed on a case with a previously isolated and sequenced GMM, an unresolved case for which no isolate was obtained, and a non‐ GMM ‐contaminated sample, all repre- sentative ...
Citrinin Determination in Food and Food Supplements by LC-MS/MS: Development and Use of Reference Materials in an International Collaborative Study
stable in all contaminated materials, with no significant degradation during the timescale of the MVS when storage was performed up to +4 °C. Next, an MVS was organized with eighteen international ...
Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide
2 and 3) performed under different exposure conditions (presence and/or absence of serum). Firstly, we identified the nanodescriptor(s) closely associated to biological endpoints. Secondly, we determined ...
Dietary exposure assessment and risk characterization of citrinin and ochratoxin A in Belgium
in three age categories (3–9, 10–17 and 18–64 years), obtained from a national food consumption survey. Furthermore, a risk characterization was performed for CIT, in which no intake values exceeded ...
Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
B. subtilis RASFF2014.1249 strain and has led to the RASFF2018.2755 and RASFF2019.3216 notifications. Moreover, a retrospective study using the same feed additive vitamin B2 samples was performed ...
