Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX
the properties of the particles consumers are exposed to. Samples were prepared by spraying 5mL in a glass vial and coated on EM-grids using the grid-on-drop method. Scanning transmission electron ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
sample preparation methods allowed to obtain a full characterization to strain level of the spiked strain in the beef sample, carrying another non-pathogenic strain of E.coli. The simplest protocol was ...
Targeted High-Throughput Sequencing Enables the Detection of Single Nucleotide Variations in CRISPR/Cas9 Gene-Edited Organisms
containing different percentages of a GE rice line carrying a single adenosine insertion in OsMADS26 were prepared and analyzed. The SNV of interest in samples containing the GE rice line could successfully be ...
Microbiological safety of aged meat.
preparation. Ageing under defined and controlled conditions can achieve the same or lower loads of microbiological hazards and spoilage bacteria than the variable log increases predicted during standard fresh ...
Development, validation and application of multi-class methods for the analysis of food additives by liquid chromatography coupled to tandem mass spectrometry
extracted with sufficient recoveries. Consequently, an alternative basic methanol sample-preparation methodology was developed. After sample preparation, the obtained extracts were analysed using ...
Guidance in selecting analytical techniques for identification and quantification of non-intentionally added substances (NIAS) in food contact materials (FCMS)
different results and it can be difficult to make meaningful comparisons. The initial approach was to attempt to prepare a prescriptive methodology but as this proved impossible; this paper develops ...
Application of a strain-level shotgun metagenomics approach on food samples: resolution of the source of a Salmonella food-borne outbreak
2 weeks after receipt of the sample, which was freshly prepared tartar sauce in a meal cooked at the school. Our team used this outbreak as a case study to deliver a proof of concept for a short-read ...
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.
sugar-coated confectionery and pristine food-grade titanium dioxide was developed. Special emphasis was placed on the sample preparation procedure, crucial to reproducibly disperse the particles before analysis. ...
Organisation of Multi-Mycotoxin Proficiency Tests: Evaluation of the Performances of the Laboratories Using the Triple A Rating Approach
prepared in house. The homogeneity and the stability of these materials were verified according to the criteria laid down in ISO 13528 using randomly selected samples. Most of the targeted toxins were found ...
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. ...
